I have a Deskjet 3550 which I use rarely as I don't print often. Lately
the need came up and it wouldn't print. Windows or Linux, the same thing
happens, when I turn it on the LED on the button blinks and the printer
never prints, the documents are queued but no printing.

I tried reinstalling the printer but I've lost my HP CD and the downloaded
drivers from hp.com don't want to install.

Any help? Should I do a hard reset? How is it done?
