Hi,
Free (send me the postage if you can) a HP LasetJet 03A cartridge. Fits 5p, 5Mp, 6P and 6MP. I got rid of the printer as it would not work with my newer MacPro sometime ago. Found the unopened box today behind some paper stacks. If you can use it, it is yours. I am in Canada, Ontario, about 80 km's east of Toronto.
