First, hello and welcome to the forum!
Second, you NEED to start from the beginning w/ a LOT more information.
CUPS is a printing technology (quote first sentence from link) - SO, please provide more incite for us to even give an opinion: 1) What are you trying to print, e.g. a file; 2) Where is this 'print job' located, e.g. on a storage device, hard drive, or other; 3) What computer system and OS are you using; 4) What app/program are you trying to print from; 5) Where are you trying to print to, e.g. a cabled or wireless printer; and 6) What printer are you using or are there multiple choices? Still have a few more questions but as is obvious, you need to educate us if you want an informed response. Dave
