Note that behind a USB->Parallel adapter your computer sees your printer as a USB printer. So checking parallel port support on your computer is not required.
Can you follow all the instructions in the section "USB printer" on https://wiki.ubuntu.com/DebuggingPrintingProblems with the printer connected and turned on? Post the output here. Thanks.
After having done so run the following commands, also with the printer connected and turned on:
sudo modprobe usblp sudo usb_printerid /dev/usb/lp0 sudo usb_printerid /dev/usb/lp1 sudo rmmod usblp
and post the output here.
