I was able for some time to print from Lion using a 10.6 driver. Recently I got a 5 yellow light blink error sign which is the sign for a print head problem.
- I installed a new print head without result (same error message).
- I opened a brand new Canon iP3000 printer. It printed one copy and then it had the same error message (it now will not print on any printer).
- My son brought over a working used iP3000. It printed one copy and it now has the same error message and will no longer work at all.
