Hey all, film_fantic here, having a few problems with two of my printers. First the HP Deskjet 840C. I recently ran out of ink and, following the chart on the HP website, bought two brand new cartriges, one colour and one black. Ever since I've installed them into the printer, it hasn't been working all too well. Firstly it takes ages to start printing and sometimes doesn't even start to print. Also, when it does print, it sometimes prints a whole load of numbers and stange letters, and other times it prints the document in a totally different colour to what it should be. Its also become unusually slow in printing out a page. I've tried re-installing the drivers, using another printer lead and trying the printer on a different computer but the same happens each time. The same problems are occuring on my Lexmark Z11 printer as well.
Any help would be much appreciated,
Thankyou very much,
