Common Unix Printing System)
You may want to go back and configure your CUPS. and let CUPS configure it as a usb device.
delete old printer then add printer and let CUPS find it.
When you do a cold boot you will hear your printer come on line. That means the bios recognize the usb and probed that device. Printers are run at a very low level.
This goes way back to print from BIOS. If CUPS sees it as Parallel then let me know.
