I have just purchase a new HP computer with Windows 7 Premium operating system. I have an old HP 2550 Laserjet Colour Printers where I used this without problem on my old Windows XP computer.
In XP I was able to use the HP Toolbox Utility that told the user the amout of toner left in pages printable also the imaging drum.
On the New computer with Windows 7, I can't get the Toolbox Utility to work. Note that everything is HP here.
Any ideas or possible software down load links to HP would be appreciated.
