USB printer does not print or prints garbage ?
There are some USB printers who do not work when the standard communication through the USB is applied. For this exception, rules need to get implemented in the USB backend of CUPS.
If your printer is connected via USB try the following steps to find out whether such exception rules could solve your problem:
Does your printer also allow to be connected via network? Or does your router have a USB port which can be used to make a network printer out of a USB printer? Try out these connection methods. If your printer works with them, continue with the following steps. Continue also with the following steps if you do not have possibilities to use your printer as a network printer. Otherwise, your printer has a problem which does not fall into this class.
Make sure your printer is connected via USB again. Run the following command in a terminal window
$ cancel -a
$ lpadmin -p <queue> -o USB-under-default=true
with <queue> being the print queue name of the printer with problems. Now your computer does purely uni-directional USB communication with your printer. Does printing work correctly now? Run
$ lpadmin -p <queue> -R USB-under-default
to remove this change.
$ cancel -a
$ lpadmin -p <queue> -o usb-no-reattach-default=true
to make the USB backend not re-attach the usblp kernel module after the communication with the printer. Does printing work correctly for you now? Undo this change via
$ lpadmin -p <queue> -R usb-no-reattach-default
