I just got done sending the test info to the printer to run a color test and was able to print out the test page just fine; which tells me that the Mac was able to communicate with the printer for the test. But then when I go to print a page, I get that error message above. What the frik?
I had selected the wrong printer from the printer list. I have two HP 812C's and I thought that since I already had the first one on the list, that I was set; not the case apparently. The Mac puts both printers on the list as separate printers even though they are identical.
