I noted recently that a Win10 box that I have, stopped printing text background color in virtual PDF printer. At first I charged it on the virtual PDF printer used (Bullzip), but that same printer works flawlessly on my Win10 laptop. Looking at the "print preview", colors are solid; printing they disappear and turn to the white/transparent background.
First note: it's not related to a single application, I tried a couple of them (Libreoffice Calc, yED Graph Editor) on both computers, and the behavior is the same, laptop works, desktop doesn't.
I tried a few virtual PDF printers: Bullzip/bioPDF, CutePDF, PDF24, Microsoft PDF, Adobe PDF, all with the same behaviour. If I print the same page with a totally different format virtual printer, "Microsoft XPS document writer", the colors are rendered properly.
I'm suspecting it's something in this system's settings, but I don't remember to have changed anything like that before... Any advice?
[Update] As I commented, the problem stays in which color I choose as a background. Let's say I use LibreOffice Calc, and put in some background formatting in spreadsheet. When I select print preview everything is fine, but when I print it with Bullzip PDF some colors are missing. The behaviour is the same with other applications, I used the spreadsheet just to ease to test.
