Firefox Update broke my company's printing config
since the latest update I experience problems with printing. In my store we print hundreds of little slips every day, they are the size of 1/3 of A4 format.
The webapp which prints them generates an A4 PDF, where only the top 1/3rd of the page is actually filled with information. Usually we print this via systems dialog, we have it set to print on Letter DL format, change the orientation 90 degrees and zoom to 270%, which gives us a perfect result.
As of yesterdays update, Firefox somehow changed the alignment rules, and the zoomed-in page now gets centred instead of aligned left, which completely breaks our process.
Is there any way to force left alignment? This is affecting two different machines exactly on the day of the update rollout. Changelog only says the print margins have been changed but I believe also the alignment has been affected by that.
