You might try reinstaling the hardware. Remove the program from add remove programs first.
Windows XP, Printer Hp photosmart 7550
Several days ago, when starting computer, I had the following message on the screen:
Unable to load driver for HPHipm11.exe (HPHipm11.exe)
Was unable to print anything. I went through the troubleshooter wizzard and everything was fine, was told to restart the computer. I did, and the items in the to be printed list, printed out fine. This happens everytime I try to print anything, I select print, nothing, shut down and restart computer and the printer works.
Any help will be appreciated.
