I installed a Comcast/Arris cable modem yesterday and and using its wireless capability to connect my Macbook Pro to the Internet. When I tried to access my HP printer today using its wifi capability (I had been doing this with no problems for several months prior to yesterday) the doc goes into the printer queue but it never prints. I have uninstalled/reinstalled the printer several times, rebooted the Macbook, restarted the printer, etc. to no avail. Any ideas? Printer is set as the default according to the Macbook but it doesn't seem to make any difference. Do I need to use wifi on the cable modem to also access the printer? HELP!
