The object data is set for each component such as a tray.

2.5 Device Selection Algorithm 2.5.1 Multi-Client / Single Server Referring to the flowchart of FIG. 10, a device selection algorithm in a multi-client / single-server connection mode will be described. That is, in FIG. 10, print processing capability data, that is, capabilities such as “printable size” and “printable resolution” are set in the multifunction peripheral 105, and the feasible value of each capability is declared as an enumerated type. Assuming that the printable size of the multifunction peripheral (MFP) 105 corresponding to the single server is A4, B5, B6, A6, B6, A7 and the printable resolution is 400 dpi, the first client (client 1-PC1) is "I want to print at A4, 600 dpi.", 2nd client (Client 2-P
C2) is "I want to print at A4, 400 dpi.", No. 3
The client (client 3-PC3) is "A3,
I want to print at 400 dpi. Shows the sequence when a request is made.

According to this sequence, the client 1
The (PC1) first requests the server (MFP) for a reply as to whether or not the desired A4 size can be processed (size processing capacity acquisition request) [step 1001], and the server (MFP) side indicates that there is processing capacity. , Client 1 (PC1) that reply is returned and processing capacity is OK
(Processing power = OK reply) [Step 10
02]. Next, the client 1 (PC1) receives 600
An inquiry is made as to whether processing can be performed at a resolution of dpi (request for acquisition of processing ability of resolution) [step 1003]. On the other hand, since the processing capacity of the server is 400 dpi, the server side replies that there is no processing capacity (processing capacity = NG).
(Step 1004). Thereby, the client 1 recognizes that the server cannot respond to the request of the client 1.

Next, the client 2 inquires of the server about the processable size in the same manner as the client 1 [step 1005] and obtains a reply that the process is possible [step 1006]. This time, inquire about the resolution [step 1007]. Server resolution is 400d
Since it is pi, a reply that the request for resolution can be met [step 1008]. Based on this, the client 2 sends a device reservation request to the server [step 1009]. In response to the reservation request, the server replies that the reservation has been accepted (reservation OK) [step 1010]. By making a reservation with the server in this way, it becomes possible to use the service of the server, in other words, the online state.

Since the client 3 wants to print the A3 size, it sends to the server whether or not it has the A3 processing capacity, that is, a processing capacity acquisition request of size = A3 [step 1011]. On the other hand, since the processing capacity size of the server is A4, there is no processing capacity, that is,
Reply that processing capacity = NG [Step 101
2]. As a result, the client 3 recognizes that the server cannot meet the request of the client 3.

2.5.2 Multi-Client / Multi-Server When a plurality of clients and a plurality of servers are connected via a network, for example, the first server (server 1-MFP1) has (a) printable size A4, B
5, A5, B6, A6, B6, A7, printable resolution is 400 dpi, second server (server 2-MFP2)
(B) Printable size is A3, A4, B5, A5
B6, A6, B6, A7, printable resolution is 400d
pi, the third server (server 3-MFP3) is (c)
Printable size is A4, B5, A5, B6, A6, A7
The printable resolution is 600 dpi. On the client side, the first client (client 1) is A4, 400 dpi, the second client (client 2) is A4, 400 dpi, and the third client (client 3). ), When printing at A3 and 400 dpi, respectively, is processed by the procedure shown in the flowchart of FIG.

That is, first, the server 1, the server 2, and the server 3 respectively notify the broker 106 of the above processing capabilities (a) to (c) [steps 1101 and 110].
2, 1103], and the broker 106 stores the processing capacity information notified from the servers 1 to 3. On the other hand, on the client side, the broker 106 sends A4, 400 dpi
Inquires about a server having the above processing capacity (processing capacity acquisition request) [step 1104]. In response to the acquisition request, the broker 106 replies that the servers 1 and 2 can meet the request [step 1105]. In response to this response, the client 1 issues a device reservation request to the server 1 [step 1106], the server 1 responds to the client 1 with permission to use [step 1107], and the client 1 and the server 1 are online. It becomes a state.

2.6 External View Information 2.6.1 External View Information Data Structure In the multifunction peripheral (MFP), the external view information of the device is (1) raster data (2) graphics command (3) logic The device information is stored in some format at the time of initialization, and when the device configuration changes, for example, when the number of paper feed tray stages increases, the external view information is rewritten.

Of these, the raster data has a data structure as shown in FIG. 12, and it is possible to have data of the upper surface, the right side surface, the left side surface, etc. in addition to the front side and the rear side as the viewpoint parameters. The graphics command is shown in Figure 13.
The data structure is as shown in (1), and in the case of a two-dimensional command system, it has data such as front, back, and top. Further, in the case of logical device information, it has a data structure as shown in FIG. In these figures, “ID” is a device ID, and indicates a print engine, a front cover, a paper feed tray, a paper discharge tray, an ADF, and the like. Further, “TYPE” indicates the type of each device. For example, in the case of a paper feed tray, a 500-sheet tray, 25
It means a 0-sheet tray, a reverse tray, and the like. "POSIT
"ION" indicates the positions of the first and second stages. And
It holds the external view data of the device in the form of raster data or graphics command for each device ID and TYPE.

2.6.2 Appearance Drawing Information Transfer Algorithm The above-mentioned appearance drawing information is rewritten by the processing procedure shown in the flowchart of FIG. That is, in this algorithm, first, the next attachable logical device list is acquired [step 1501]. Next, it is checked whether the ID which is the attachable logical device list data is 0 [step 1502]. Here, the mountable logical device list data is data in which ID1 is defined in the print engine and ID2 is defined in the paper feed tray and the like, as shown in FIG. 15B. Therefore, if the ID is not 0, it is confirmed whether the external view data structure matches the logical device information format [step 1503], and if they match, the above-mentioned TYPE [step 1504] and P.
OSITION [step 1505] is acquired, logical device information data is created [step 1506], and step 150 is executed to acquire the next attachable logical device list.
Return to 1.

If it is determined in step 1503 that the external view data structure does not match the logical device information format, it is checked whether the external view data structure is a graphic command [step 1507]. Add structure to graphic command [Step 1508] Step 150
Return to 1. On the other hand, if it is determined in step 1507 that the external view data structure is not a graphic command,
The raster data of the device is written in the external view information, and [step 1509] and the procedure returns to step 1501. When these processes are repeated and the ID is determined to be 0 in step 1502, this process ends [step 1510].

2.6.3 Display of external view and response when instructed by pointing device 2.6.3.1 For raster data FIG. 16 shows the external view executed between the client and the server. It is a flowchart which shows the flow of the process by the raster data regarding a display.

When the external view of the server to be used is displayed on the display device on the client side, since the display screen on the client side is 400 dots vertically and 600 dots horizontally, first of all,
An external view information request is sent from the client side to the server side [step 1601]. In this case, the command CMD =
01 and dot information (X = 600, Y = 400) are transmitted. In response to this, the server side acquires the external view raster data [step 1602] and enlarges or reduces the X / Y size according to the display size on the client side [step 1603]. Then, the data is returned to the client as external view data [step 1604]. On the client side, display on the display screen based on the received external view data (or write to the display memory)
[Step 1605]. The user or operator
Looking at the display on the PC, the desired paper size is, for example, 2
When the location of the tray on the tier is designated by a pointing device (not shown) [step 1606], the pointed coordinate (x, y) pointed to is acquired on the PC side [step 1607] and the acquired coordinate is notified to the server side [ Step 1608].

On the server side, the received coordinate position is calculated, which region the position corresponds to is determined, and the device ID, TYPE, and POSITION described above are acquired [step 1609]. Then, the information of the device is acquired [step 1610], and a character string expressing the state or ability of the device is created [step 1611]. The character string is, for example, "second paper feed tray \ n A4 size,
"500 sheets \ n READY \ n". In addition, here, \ n represents a line feed. The character string thus created is transmitted from the server side to the client side [step 1612], and the client side displays the transmitted character string on the display screen in addition to the external view [step 1613].

2.6.3.2 In case of graphics command FIG. 17 is a flow chart showing the flow of processing by the graphics command relating to the display of the external view executed between the client and the server.

When the external view of the server to be used is displayed on the display device on the client side, since the display screen on the client side is 400 dots vertically and 600 dots horizontally as described above, first, the appearance from the client side to the server side is shown. A diagram information request is transmitted [step 1701]. In this case, the command CMD = 02 and dot information (X = 600, Y = 40
0) and are transmitted. In response to this, the server side acquires the appearance drawing graphics data [step 170
2], sending the external view graphics data to the client side in response to the client's request [Step 170
3]. At the same time, the server interprets the graphics command and develops it into raster data [step 170].
4]. The client side similarly interprets the graphics command and develops it into raster data [step 170
5]. The external view information expanded into raster data is displayed on the display screen of the client (or written in the display memory) [step 1706]. The user or the operator, looking at the display on the PC, specifies the desired paper size, for example, the location of the second tray with a pointing device (not shown) [step 1707],
The PC side acquires the pointed designated coordinates (x, y) [step 1708] and notifies the server side of the acquired coordinates [step 1709].

The server side calculates the received coordinate position, judges which region the position corresponds to, and acquires the above-mentioned ID, TYPE, and POSITION [step 1710]. Then, the information of the device is acquired [step 1711], and a character string expressing the state or ability of the device is created [step 1712]. The character string is, for example, "second paper feed tray \ n A4 as described above.
The size is 500 sheets \ n READY \ n ". The character string thus created is transmitted from the server side to the client side [step 1713], and the client side displays the transmitted character string on the display screen in addition to the external view [step 1714]. 2.6.3.3 In the case of logical device information FIG. 18 is a flowchart showing the flow of processing by a graphics command relating to the display of an external view executed between the client and the server.

When an external view of the server to be used is displayed on the display device on the client side, the display screen on the client side is 400 dots vertically and 600 dots horizontally as described above. A diagram information request is transmitted [step 1801]. In this case, the command CMD = 03 and dot information (X = 600, Y = 40
0) and are transmitted. In response to this, the server acquires the external view logical device information [step 1802], and adds ID, TYPE, and POSITION to the external view logical device information.
If there is [Step 1803], the client side I
D, TYPE, and POSITION are transmitted [step 1804]. Also, the display data is extracted and transmitted [step 1805]. On the client side, ID, T
Store YPE and POSITION [Step 180
6], the external view data transmitted from the server side is displayed on the display screen of the client (or written in the display memory) [step 1807]. When the user or operator looks at the display on the PC and designates the desired paper size, for example, the location of the second tray with a pointing device (not shown) [step 1808], the pointing coordinate (x, y) is acquired [step 1809] and the server side is notified of the ID, TYPE, and POSITION corresponding to the acquired coordinates [step 1810].

On the server side, the received ID, TYPE,
The information of the corresponding device is acquired from POSITION [step 1811], and a character string expressing the state or capability of the device is created [step 1812]. The character string is, for example, "second paper feed tray \ n A4 size, 500 sheets \ n READY \ n" as described above. The character string thus created is returned from the server side to the client side [step 1813], and the client side displays the transmitted character string on the display screen in addition to the external view [step 1814].

In each of these three patterns, the client side only has to follow the communication protocol and does not need to have any unique information on the server (MFP) side.

2.7 Setting of Operation Mode from Remote Client 2.7.1 Case of Raster Data and Graphics Data FIG. 19 is a flowchart showing the flow of processing when setting the operation mode from the remote client.

When displaying the external view of the server to be used on the display device on the client side, since the display screen on the client side is 400 dots vertically and 600 dots horizontally, first of all,
A screen information request is transmitted from the client side to the server side [step 1901]. In this case, the command CMD = 0
3 and dot information (X = 600, Y = 400) are transmitted. In response to this, the server side acquires screen data [step 1902] and enlarges or reduces the X / Y size according to the display size on the client side [step 1903]. Then, it is returned to the client side as screen data [step 1904]. On the client side, it is displayed on the display screen (or written in the display memory) based on the received screen data [Step 190
5]. Note that the display screen on the server side is as shown by reference numeral 1900, and in addition to the display screen of 400 dots in the vertical direction and 600 dots in the horizontal direction, the setting screens such as “printing direction”, “vertical” and “horizontal” are set. This screen is a condition setting screen for a printer or the like, and the setting value on the server side can be changed by clicking the pointing device on the remote side, in other words, the client side. Then, the user or the operator looks at the display of the PC and, for example, designates the portion in the print direction “horizontal” with the pointing device [step 1906], and the PC acquires the pointed designated coordinate (x, y). [Step 190
7], notify the server of the acquired coordinates [Step 1
908]. The server side calculates the notified coordinate position, determines which area the position corresponds to, and gives the instruction part corresponding to that area, that is, the operation instruction corresponding to the display part clicked on the client side. Will be executed. For example, the server can be started by clicking the start key portion from the client side on the display screen on the server side. Step 1909
When it is determined which area is the area instructed on the server side by, the set value, in this case, "horizontal" is stored [step 1910], and the server side acquires the next screen data and [step 1911] and replies to the client that the set values have been saved [step 1912].

2.7.2 When Transmitting / Receiving by Button Information FIG. 20 is a flow chart showing the flow of processing when the operation mode is set by the button information from the remote client. Note that the button information is shown in FIGS.
It is possible to display a button for instructing server operation on the display screen, send the function and position of the button to the client side, and click the position of the button on the client side to operate it. It is information that can be provided.

When the external view of the server to be used is displayed on the display device on the client side, the display screen on the client side is 400 dots vertically and 600 dots horizontally as described above. Is transmitted [step 2001]. In this case, command C
MD = 03 and dot information (X = 600, Y = 400) are transmitted. In response, on the server side,
Obtain the button information indicated by w_ptr [Step 2
002], if there is such button information [Step 200
3], button information is sent to the client side. The button information in this case includes ID information, X, Y coordinates, width, height,
TYPE and the like [step 2004]. Furthermore, T
The button raster data indicated by YPE is acquired and transmitted [step 2005]. On the client side, the transmitted ID, TYPE, and POSITION are stored [step 2006], and the data transmitted from the server side is displayed on the display screen of the client (or written in the display memory) [step 2007]. When the user or operator looks at the display on the PC and specifies the desired button position with a pointing device (not shown) [step 2008], the PC side acquires the pointed designated coordinates (x, y) [step 2009]. , Calculate the corresponding button ID from the acquired coordinates [Step 20
10], button ID corresponding to the coordinates acquired on the server side
Is notified [step 2011].

On the server side, the value set from the received button ID, in this case "horizontal", is saved [Step 20
12], the next screen data is acquired [Step 201.
3] together with notification that the set value is saved on the client side [step 2014]. Note that step 20
After step 13, the process returns to step 2001 and the second and subsequent processes are repeated. At that time, the data indicated by the window_ptr in step 2002 is
The button information is represented by t_ptr.

The data structure of the button information is as shown in FIG. 21, and the button data has a list structure from the window pointer. Here, “ID” is an identifier attached to each button, “TYPE” is the button shape, “X coordinate” is the X-axis direction coordinate from the upper left origin, and “Y”
"Coordinates" are Y-direction coordinates from the upper left origin, "width" is the width of the button, "height" is the height of the button, and "next_p tr " is a pointer to the next button (0 is a termination).

FIG. 22 is a specific example of the button information displayed on the display screen. Ten keys, a start key, etc. are assigned corresponding to the X coordinate and the Y coordinate. FIG. 23 is a diagram showing the raster data structure of a button.

2.8 Operation Instruction from Remote Client FIG. 24 is a flowchart showing the flow of processing when an operation instruction is given from the remote client to the server.

When the operation is instructed, since the contents displayed on the display screen are referred to and executed, first, the client side requests the screen information from the server side. In this case, since the display screen on the client side is 400 dots in the vertical direction and 600 dots in the horizontal direction, the command code and the display size, that is, the command CMD = 03 and the dot information (X = 600, Y = 4).
00) and [step 2401]. In response to this, the server side acquires the screen data [Step 240
2], the X / Y size is enlarged or reduced according to the display size on the client side [step 2403]. Then, it is returned to the client side as screen data [step 2404]. The client side displays (or writes in the display memory) on the display screen based on the received screen data [step 2405]. When the user or the operator looks at the display on the PC and specifies the “start” button portion 2400 with the pointing device [step 2406], the PC side acquires the pointed designated coordinates (x, y) [step 2407],
Notify the server of the acquired coordinates [Step 240
8]. On the server side, the notified coordinate position is calculated, and it is determined which area the position corresponds to [step 2409], and the designated portion corresponding to the area, that is,
It is determined that the position is the start button clicked on the client side, and the copy job is started [Step 241.
0]. Then, it responds to the client side that it has acknowledged the operation instruction [step 2411].

Since the processing procedure when the operation instruction is executed by the button information is the same as the processing procedure in which the operation mode shown in FIG. 20 is replaced with the operation instruction, the description thereof is omitted here.
