I have a Photosmart C4780 all in one printer, and I can't get it to print anything. When I send anything to the printer it acts like it's going to print (makes noise, takes up paper) then it just stops. The screen says "printing" but no matter how long I wait it never does. Last night I was able to get it to print an alignment page, but I was apparently out of black ink, so today I replaced the black cartridge and now it won't even print the alignment page.
Even though the problem is obviously with the printer, I have uninstalled (with scrubbing) and reinstalled the software, and I have also upgraded the firmware and reset the thing about 50 times.

Ok so miraculously my problem is resolved. I started going through all of the options in the hp utility app and after running the paper feed cleaning, it started working again.
