The printer does not print, blink the pilot lamp instead. I have delete the function on Windows, disconect the USB Cable, and reinstall all over again, refilled the ink. And still blinking...

If there is something wrong with the printer, you should get a error message describing the error.

Does the printer have a blinking orange light after you give the print command? Then there is an error in the printer. If you have documents in the print queue, delete them. Remove the printer cable. Shut the printer down, shut the computer down. Reconnect the cable and turn everything on again.
If there is still a problem there might be something wrong with your printer.

If you don't have a blinking light after the print command on the printer, then try changing the printer cable. If not working, try another USB port. If still not working, reinstall the printer.

Remove the printer from your PC, delete the printer, restart the machine. Attach the printer, preferably with a USB cable and not the parallel cable. If you already had it using USB, attach it to a different USB port. Reinstall using the Windows driver instead of the driver that came with the printer. Your printer should work after that.

Try to reinstall the driver or change the USB cable.In worst case there is a problem in logic board assembly in your printer

When you reinstalled it did you unplug it from the computer. Often links to printers are lost, it's a Windows thing, frequently people reinstall in desperation, forgetting to uninstall the original and disconnect the printer USB. So, unplug the printer USB from the computer, go to control panel,and printers and delete the printers that you are going to reinstall which you see there. Then go to add and remove programs and remove all software.
If there are print jobs pending you may not be able to uninstall or delete, so click the printer and delete all jobs pending, then try the uninstall again.
When all is uninstalled, restart the system and reinstall, plugging in the printer only when the software asks for it.
It being an HP the uninstall option may well be on the installation disc so you can use that if you wish.

If you haven't tried it yet, delete the printer from the 'Printers and Faxes' folder in the Control Panel, make sure the printer is connected and turned on, then reboot the computer.

This will force Windows to reinstall drivers for it and should return functions.

Check that is defined as default printer in 'installed printer' in Windows, and that you are not sending documents in printout to another non connected printer present in Windows under 'installed printers'.

Unplug completely computer from power socket and from USB for 10 minutes, to get rid of electrostatic problems on USB. Plug everything back and restart.

Check the USB cable, replace USB cable with a different one to check if it was the cable.

Uninstall printer from 'installed printers' in Windows (delete). Disconnect printer from USB, reinstall printer from printer software CD or downloaded driver. Connect printer to usb only after installing, or when explicitly required by software, this is important

Here is link to driver download, put your windows version in select OS box.

Hello, You may check to insure the USB cable at the printer or at the computer is connected properly and didn't come loose by chance. Try disconnecting the USB cable from the computer, wait ten seconds then reconnect. This will let Windows "find" the printer again. Worse case scenario, you could delete the printer through device manager, reboot you computer and Windows will "find" the printer and reinstall the driver automatically on restart. Also check that the ink cartridge(s) is seated properly.

We know it isn't the printer or the USB cable. We know it isn't the software. You are running Windows XP on both the desktop and laptop, correct? On your desktop, you go to 'Start''Settings''Printers' and is the printer there ?? Try this; go to 'Start' 'Settings''Control Panel'. Double click the 'System' icon. Click on tab 'Hardware', click on 'Device Manager'. Do you see a yellow (!) on any Universal Serial Bus Controller. If not, were good. Check all USB ports with a USB mouse or device to make sure they're active.
