I had this issue arise and all the posts i could find say to change my default printer. It isn't the default printer in my case. I'm not sure about your situation, but when I'm trying to print after I log in and access a program through the web from my home computer and I'm trying to highlight and print via "print selected text " on that program that I need to print, and if I try to print from it then I'll get this .XPS default prompt even though my printer is set to my current printer and not the default xps window writer whatever. This has to be because somehow the system I'm logged onto isn't configured for printing and is being recognized with its default printer, the .xps thing, instead of my home default printer when I select and highlight the text I want and try to print the selection. The only way to fix it is to logout completely from the program and log back in and it then recognizes my computer printer and isn't the online's system window's default. I can't prove it but at least it's a documented instance of not just the default printer causing the problem. Good luck!
