Operating System: Arch Linux KDE Plasma Version: 5.26.2 KDE Frameworks Version: 5.99.0 Qt Version: 5.15.7 Kernel Version: 6.0.6-arch1-1 (64-bit) Graphics Platform: X11 Processors: 24 × AMD Ryzen 9 5900X 12-Core Processor Memory: 31.3 GiB of RAM Graphics Processor: NVIDIA GeForce RTX 2080 SUPER/PCIe/SSE2 SUMMARY I am in the US and mainly (read: pretty much always) print US Letter when I need to print something. I recently had to print an A4 PDF, so I ordered some A4 paper and gave it a go. I tried just about everything in the printer dialog in okular but could not get any combination of options to work and actually print the thing full size and not strangely scaled (smaller than US Letter, also). I then tried just opening the PDF and Firefox and printing from there: I set the paper to A4, hit print, and it worked perfectly. Issues I had: Changing the paper size under the printer "Properties" seems rather broken. When I go from Letter to A4, non of the margins update, and they also stay in inches vs mm/cm. Even manually adjusting the margins to be the "proper" size that I found for A4 did not result in the page being printed full size. Under the general printer dialog, I tried 'Fit to printable area' as scaling, along with none (print original size), and fit to the full page. None of these options worked to make the PDF print properly to the full A4 page size instead of being shrunken in the middle with huge top/bottom margins and sides. I would expect that the 'none' option should work since the document needed no scaling and was natively A4. I also played with the 'Force rasterization' option to little effect. Another tangential issue I had was attempting to scale and print the A4 document to US Letter - which also didn't work and was either way too small or just cut off. I guess there is something not quite right in both dialogs and how scaling is done and generally setting the paper size. And to note it doesn't seem to be just my cups setup, as Firefox printed it perfectly using its dialog and paper settings first go. OBSERVED RESULT A4 document wouldn't print properly on A4 paper (and wouldn't also scale on Letter paper) EXPECTED RESULT The A4 document when A4 paper is chosen would print on A4 paper. Or, if Letter is select and Letter paper is used, then using the scaling options to print to page would scale the A4 document and print it correctly.
