HP 959C printer not printing blue colour?

  compumac 10:29 30 Sep 2009

My HP 959C is now nine years old. It has been a good workhorse but I found this morning that it will not now print in blue. I have three spare colour cartridges and changing the cartridge has had no effect. I have cleaned the contacts and also tried to print from another PC with the same result.
Two questions
1) Any thoughts on corrective action?
2) What recommendations are there for a replacement printer? I have also a dedicated photo printer and a separate Canon scanner. I am not averse to a combined scanner/printer unit.

Any other recommendations for new multifunction unit?
