I have a HP DeskJet 5900 connected and installed on my MacBook however I would also like to share that printer with my desktop computer, which is running Windows XP. I should also add that the 3 computers in the house, are all connected via Wireless LinksSys. The MacBook automatically connects to the internet from Linksys so I figure there shouldn't be any problems but I can't get this to work! Is there any way to share my printer with my Windows XP desktop computer, without buying any software/hardware? If so, how?! Last night I searched the internet for instructions but nothing seemed to help. Thank you!
