Problem with printing at reduced scale, did not notice it before a few days ago so could have been after a recent update. Am now using Firefox 90.0 for Linux Mint 19.3. Printing to US Letter size (which had been broken with "na_letter" being stuffed in to the config at one point, but I switched it back to "US Letter" and then it started working again a few months ago - Thank you). I see some similar questions listed, so this may be simply adding information to something known: Printing with "Fit to page fit" works fine, with correct preview. Print with scale set to 100% works fine, with correct preview. Printing with scale set to less than 100% (say 70% or 80%) showed in the preview the page rescaled as expected. The actual printed output is also rescaled as expected, but the page size gets cropped at the right and bottom by what appears to be the same percentage, ending up with lost content. The bit that does print seems to match what is shown in the print preview perfectly, suggesting it would have been totally perfect if the print area had not been cropped along with reducing the text and image sizes. I tried the "Print using the system dialogue" option, and the printed result had the same pathology. Same problem also happens when I print to PDF. For this I tried doing the same thing twice, both scaled at 70%, and on comparing found that the preview in firefox had also become cropped a bit but not to the same extent. I did not notice any cropping for the first print to PDF, but now seem unable to get back to what I saw originally in the preview, with correct resizing and no cropping. Playing around some more with printing at 100% vs 70% vs 80% to "fit to page width", I seem to be getting changing crops happening each time in the preview for the reduced sizes. But the preview and print are both still correct for 100% scaling and for "fit to page width". Sample web page I used here was https://getpocket.com/explore/item/a-shoulder-workout-for-better-posture?utm_source=pocket-newtab The screen shot shows the preview after the first reduced print to PDF, with no settings changed. The little bit of side cropping seen in the preview did not happen when I did the first print to PDF.
