I have an hp7550. It has worked fine for over a year. Now I cannot get it to print when I send something to print nothing happens I chcck printer status and it says the print job is in Q but needs user intervention and printer must work offline. I have windows ME. I have tried all of Dells self help solutions, I have tried to reload printer software. hp 7550 is default printer. Printer works fine from self diagnostics and test print from its own control panel. I just don't seem to have communications between computer and printer.
