how can i get my HP2550 to print under the new os
i have an HP 2550 laser jet printer and now running the new os i just installed..i can print a print job ,then i try to print another and it will not print. it said "waiting for printer to become available"and then i have to unplug the usb in the back or turn off the printer and back on again to get it to print..The hp 3.0 update has this printer as being supported and it shows up on the add printer as a correct printer with the right ram .ect.....
