HP deskjet 5550 printer not printing.

First step is to see will if it print a test page.
Go to Start, settings, printers. Right click on the printer, properties, print test page.If that doesn't work there should be a head cleaning option in properties that will make it clean the print heads.
Try the self-test? I'm not sure on the 5550 printer, but do this:With the printer ON,
1. Press and hold the power button
2. While holding the power button, press the resume button 4 times
3. Release the power button

To get the page count on a Deskjet 5550:

- Hold down the Power button.
- Press the Resume button 4 times (without letting go of Power).
- Let go of the Power button.

A self test page will print out containing the page count.

For page count or configuration page instructions for other printers, copiers, and fax machines, check out How to Print Configuration Pages.

Go to the control panel, go to printers and faxes, click or righ click on your printer, choose printer preferences and look for the basicsr section.
On the "Page order" frame choose "Back to front" and then click Apply.

That is strange
Try changing the default to a different printer (Microsoft XPS Document Writer) see if it prints to it...

Then (If that works) try switching the 5550 back to default.

If that don't do it, uninstall thee printer, reboot and reinstall the printer.

IN THE PRINTER SETTINGS YOU MAY HAVE THE "PRINT TEST PAGE" SELECTED
