If you are experiencing printing issues, the first thing to do will be to reboot your computer and turn off, then back on.... of the printer. This should resolve 99% of printing errors when the printer just wants to do nothing.
Also check that the printer has power and is online. Sometimes the cables wiggle themselves loose.
Check you toner and paper levels.... maybe the printer is needing more supplies.
Contact your help desk via a ticket if none of these do the trick.
