After we moved house I had a tussle with the HP printer I`d bought only a few months earlier, partly my fault as I forgot to get the BT engineer to connect it online for me, it ended up being thrown out!!
I bought a cheap Canon printer ( hard wired), prints are fine but copying not so sharp. I`ve just bought a new black cartridge from a company I`ve used before, the one I bought the printer from wanted twice the price !
I`ll see how long this cartridge lasts.
