Hello Ijez,
I see no one has responded to this post yet. So, at this point I would recommend contacting your local Xerox Support Department to speak with a Product Specialist for more assistance.
Please call 1-800-821-2797 or 1-800-835-6100.
I managed to set up the Xerox B210 to work with Linux (Lubuntu 20.04 LTS more specifically), both through USB and through WiFi. However, I do not see any way to set the print quality or resolution, and on printouts these appear lower than possible (I am guessing they are 600x600 DPI). In particular, the print quality of the page printed when the printer is turned on is visibly better than anything I can print. Is there a way to fix this?
