i have an older lexmark monochrome laser printer. it was working fine until the most recent win 10 upgrade, now i can no longer install it as the default printer or print to it. I have removed the printer and reinstalled it. I have updated the drivers. I can see the printer in the devices list. I cannot set it as default printer. The manufacturer say it is compatible with win 10 but I cannot print to it. I would like to be able to use it as my default printer and only go to my injet when I need color copies.
