To add to my bother this evening my computer called my old cartridge a mismatch. You should have heard the rumpus the printer paper made, trying to get in the computer and out of the computer at both one and the same time. To cut a long story short I had a new manufacturer's cartridge in stock at home. After the old one was out. I put in the new manufacturer's cartridge. The new cartridge is working fine.
Virgin Media is still down.
