my Mac all the sudden is not recognizing my printer. (however I am still able to print from my phone?). I already deleted the printer, reset the printer settings on the Mac, restarted my computer. When I go to add the printer (it's an hp 9150), I keep getting "client-error-request-value-too-long" message. I've downloaded the hp app on the computer as well, but that didn't do anything. I restarted the printer, but I don't think it's a printer issue b/c I can print from my phone. do I need to just take my Mac in? what is the issue?
