HP LaserJet keeps on printing garbage characters
ANSWER : Solved. The same problem started with my HP LaserJet 4000 a few days ago. I tried unplugging, changing the print driver, re-installing the print driver, checking if print jobs were stuck and it was clear. Finally, I decided to go into the printer’s settings and reset the printer back to factory settings. It worked! That reset cleared out whatever the problem was and now it’s working perfectly. Wish I had thought of that sooner.
