USB Printer Controller Utility not working
I've been using succesfully for a while the USB Printer Controller Utility with a Samsung ML-1520 printer.
Suddenly, the print function stopped working and the Auto-Connect Printer List window did not show my printer any longer - worse, it began beeping a sound periodically, perhaps trying to fetch it around. PC is Windows 10. Thank you for any hint. Stopping the printer server on the router side makes the sound stop altogether
Wireless router is an Archer D7 with firmware 0.9.1 1.1 v002d.0 Build 150824 Rel.40904n - Please note the select drop down lis did not allow me to select "D7" as a model but at most "C7".
USB printer controller utility software version is 1.12.0927
Driver version is 1.75.0
