[catch22]

I have an HP deskjet920C which has been a GREAT printer for me!!

NOW...just within the last 2 days it will not print in BLUE. (I am guessing about the color exactly - but from the weird colors it makes things...I am guessing it is BLUE that is not printing).

I aligned the print heads first - as I thought the lines on the FLIP's I printed looked weird and not straight. Then I went to Services under Printers and cleaned the ink cartridges - then went to Primed and did this all a few different times and changed the color cartridge THREE TIMES...thinking it was just bad ink cartridges! What am I missing...or is this how PROBLEMS begin and it is on its last legs??? Please someone...ANYONE...help me!!!
