Can you now power-cycle the printer and do print jobs. After each print job run the two commands
lsusb sudo time /usr/lib/cups/backend/usb
Can you keep printing without power-cycling the printer now?
Attach error_log if it does not work. Compress your error_log only if it is not accepted uncompressed.
