Bugs Killed

Windows

Sharp BP-70C31 printer stopped printing

Printing to the Sharp BP-70C31 stopped after it had worked earlier in the day. The existing printer instance was removed, the device was rediscovered and reinstalled with Add Device, a test page printed successfully, and the printer was set as default.
