Print area cut

[kayvax]

Hi everyone,
I am using:

• glabels-qt 3.99-master564 (2da9b2d 2021-02-06)
• Toshiba Tec B-EV4D-GS14
• cups 2.4.1
• custom defined media, peel off 32mm by 20mm labels with 2mm gap
  I have been using glabels-3 for a long time with this printer and had no real problems, but lately printing with glabels-3 started to cut print area to 20mm by 20mm. I started looking around and found that glabels-3 is getting obsoleted and glabels-qt is current project to use so I compiled it and for few days it was working without issues - labels printed with whole print area.

But I started having issues again. Print is cut off on both left and right edge, limiting printing area to 20x20 mm rectangle. The only way I found to move around this issue is to add new printer (same settings, same ppd file, just different name in cups)

Does anyone have idea how could I narrow the source of this issue? Adding new printer each time is not really a fix.
