the printer is in constant use
the pattern should be produced from the computer software
the Windows version is XP
A negligible amount of ink has appeared when I tried to copy a page. This is what happened before I cleaned the print heads. Shall I just get a new printer? Incidently, it's connected by wi-fi.
I'm afraid this routine has had no effect whatsoever so it looks like a new printer is called for. Are you allowed to recommend a reliable one - we don't ask much of it (if it used the same ink cartridges it would be helpful!).
I'm sorry to go down as one of your unsuccessful jobs but thank you very much for your advice.
