Start by disconnecting the computer and doing a simple diagnostic print as
shown at:

If this prints a simple nozzle pattern of black, cyan, magenta and yellow then
the problem may lie with your driver.

I don't know much about this particular HP printer but the newer ones
come with new heads on the cartridges themselves. However, you did
say that it is an old printer so are the heads on the printer itself
(likely) or on the cartridge? I had an Epson printer at one time
which did exactly the same thing and it turned out that the printing
head for black was plugged up. That's the nice thing about the new HP
printers (mine anyway), you throw the head away with the cartridge and
install a new one every time so chances of them plugging up are slim.

Stupid question time- did you pull off the tape covering the print nozzles?

Did you try the self test as suggested by Bob?

Never mind. I bought a new printer yesterday. Just can't do without
a printer for too long.

By the way I did do the print test and no black appeared. Mostly like
it was a clogged print head, although I did try cleaning it. Anyway
printers are pretty cheap so what the heck............
