... and it just ain't working! I have an XP laptop with Service Pack 3, an Imac running 10.5.4, and a Canon MP510. The Mac and the printer are wired together, and they love each other. Both the Mac and laptop share a wireless net connection to my home router/modem. I've spent hours trying to get this laptop to print to that printer. Sharing is enabled, although in the Mac Sharing menu, there is no sign of "Windows Sharing". I've tried installing Bonjour on my laptop, and apparently the laptop can "see" the printer on the network, but can't print to it. I've seen many posts where the MAC has trouble printing to an XP wired printer. Here's the opposite. Should I get out the hammer, or is there some hope here?
