3010cn on Win10/64 driver issue

I can print a windows test page on my network 3010cn printer. But no application, be it Libre Office Writer or Windows Notepad (or a simple print from any browser) can print.
When I look at a print preview in Libre Office Writer, the paper size is set to 0 (zero height and width), allthough its set to A4 in the printer settings. This seems to be the issue: Notepad simply crashes when asked to print, and other applictions just won't print. It seems that the applications do not receive the paper setting from the printer.
I've completely removed printer and drivers and reinstalled everything, using both the old driver from 2006 and the newer Vin7/64 from 2011. The issue remains. Any help appreciated.
