Printing colour problem

[Wheelbrace]

I have just installed a new colour cartridge in my HP Deskjet which I connect to TWO laptops .
When printing from my main laptop the blue colours range from pink to magenta yet from my second laptop the blue is perfect.

Anyone any ideas? Thanks

Delete the printer driver from the laptop that isn't working, download it from HP's website and install it again.

Thank you ChuckFickens. Can you explain to a novice how to delete the driver. The rest I think I can cope with
Thanks again

Click start, control panel, printers and faxes, right click on the icon for the printer and select delete.

Thanks again - sure I can do that!
