I installed my 2550 on my new Windows 7 computer, printer works fine so the driver must be OK. Problem is that the support programs on the CD will not run. All of them generate a Java error. I need to run one of the maintenance programs - or I might as well junk the printer! All my system s is on auto update so I really am lost.

Only the Universal Print Drivers (UPD) are supported in Windows 7.

SAME PROBLEM! Wasted an hour talking to someone in India who suggested that I replace all my toner cartridges, and then that I simply upgrade my printer. THERE IS NOTHING WRONG WITH MY PRINTER!! Except that the colors are misaligned, and I can't align them without the bloody TOOLBOX which won't run on my Windows 7 64 bit S.P. 2 operating system. It is RIDICULOUS that HP doesn't have a solution for this. I may never buy their products again.
