SUMMARY
Okular overrides the printer's default settings and user preferences from
Windows, and forces the output to become 108 x 297mm in landscape orientation,
on the Zebra GK420t printer.

But our labels are 3x2 inches (76,2 x 50,8mm) in portrait orientation, and this
is what is set both in "Printing Defaults" and "Printing Preferences" on the
printer in Windows.

The result is a blank page.


STEPS TO REPRODUCE
1. Install the driver "ZDesigner GK420t"
2. Connect the printer, Zebra GK420t
3. Load the printer with labels that are 3x2 inch in size
4. Open printer properties -> Advanced -> Printing Defaults
5. Set width to 3 inches
6. Set height to 2 inches
7. Set orientation to Portrait
8. Click OK
9. Go to General -> Preferences
10. Repeat steps 5 to 8
11. Click OK once more
12. Open Demo.pdf
13. Print the document to the Zebra GK420t printer

OBSERVED RESULT
Blank page/label

EXPECTED RESULT
Text printed on page/label

SOFTWARE/OS VERSIONS
Windows 11 - 25H2


ADDITIONAL INFORMATION
1. Works fine with Acrobat Reader
2. Default printer is set to "Microsoft Print to PDF"
3. Have tried to set GK420t as defualt printer, with no luck, but the papersize
in Okular changed to 0.75 x 0.25inch (19,0 x 6,3mm)
