I am running 64 bit Linux Mint 19.1, the Cinnamon desktop 4.0.9, with kernel 4.15.0-45-generic.

Two days ago an update to ghostscript dated 20 FEB 2019 appeared, and was applied to two of my machines (One is an Intel and one is an AMD, but both are kept fully updated) that share a networked HP OfficeJet 6700 Printer.

At some point following the update, I happened to print a document, and ended up with a blue background on every page, even otherwise blank second sides. This occured regardless of a variety of originating applications I used, such as LibreOffice, various text editors, and even the CUPS "print test page" option.

It took me a while to troubleshoot this on that first machine (trying different apps, reinstalling CUPS and so forth) until I realized the new ghostscript update was the issue and that (after trying to print from the second machine) it was affecting both machines.

I should note that, using the "non-CUPS" appearance of the same printer, no blue background is present, but of course this provides no features like ink-level reporting, dual-sided printing, etc.

I "restored" the ghostscript stuff from the last Timeshift backup and that cured the issue but I think this is a serious matter that should be addressed immediately (not the least because it's hard to read black text on a blue background and it wastes a lot of ink).

I first posted this at <https://forums.linuxmint.com/viewtopic.php?f=47&t=288613#p1598888> and then sent an e-mail to <email address hidden> (whose name was on the update information) who advised me to post this bug here.
