CUPS.org User: mike Investigating, this might be over-optimization of the option storage code. |

Version: 2.1.0

The section on printer instances in the CUPS documentation (section "Creating Saved Options" in [1]) says:
"Instances do not inherit lpoptions from the main queue."
I tried sending a print job to the instance and as far as I can see, the values specified for the main queue are not applied (which is the expected behaviour).
However, the output of
lpoptions -p <printername>/<instancename> -ldoes show values set for the main queue for the instance as well. If I understand the documentation correctly, this is incorrect.Steps to reproduce (I ran them on Debian GNU/Linux):
set up a printer with the attached PPD file, e.g. print to a file (cups-files.conf must contain "FileDevice Yes" in that case).
sudo lpadmin -p testprinter -v file:$HOME/tofile-testprinter -E -P Ricoh-MP_C3503-pxlcolor-Ricoh.ppd
create a printer instance "testprinter/myinstance":
lpoptions -p testprinter/myinstance -o Resolution=1200dpi
check value of PageSize returned from "lpoptions" for the instance:
lpoptions -p testprinter/myinstance -l | grep PageSize
output:
PageSize/PageSize: A3 A4 A5 A6 B4 B5 B6 Legal GovernmentLG EngQuatro *Letter Statement F Folio FanFoldGermanLegal Tabloid 12x18 11x15 10x14 SRA3 SRA4 Executive Env10 EnvMonarch EnvC5 EnvC6 DLEnv 8Kai 16Kai
The PageSize is "Letter" as specified in the PPD file (as expected).
change PageSize for the main queue:
lpoptions -p testprinter -o PageSize=A3
check value of PageSize returned from "lpoptions" for the instance:
lpoptions -p testprinter/myinstance -l | grep PageSize
output:
PageSize/PageSize: *A3 A4 A5 A6 B4 B5 B6 Legal GovernmentLG EngQuatro Letter Statement F Folio FanFoldGermanLegal Tabloid 12x18 11x15 10x14 SRA3 SRA4 Executive Env10 EnvMonarch EnvC5 EnvC6 DLEnv 8Kai 16Kai
The PageSize is "A3" as specified for the main instance "testprinter".
Expected behaviour:
The value for the "PageSize" option for the printer instance "testprinter/myinstance" should not be affected by the main instance "testprinter" and should therefore still be "Letter".
I have tested this on Debian 8 ("jessie") with the preinstalled CUPS version (1.7.5) and on Debian unstable with version 2.1.0.
