Dot matrix printers eh? You leave them standing for a year and then when you go to use them again they don’t work.
In retrospect this was a bit silly. And my joy in finding that I could get complete set of inkjet cartridges for a fiver may have been misplaced as they might have gummed everything up. I’ve narrowed the fault down to the print head or something else. A replacement print head (which may or may not fix the problem) can be obtained for around twenty five quid. So the question is: do I spend the money on a new print head or do I throw the printer away?
