Just finished sharing my HP 5850 printer on my home network in Windows 7 with my Windows XP machine. Sounds easy yes?. Well it took me a while to do this, here is what I went through.
USB connection to the 5850 from Windows 7 machine, whoops, no real driver for this so you need the 5600 Series (HPA) driver for it to function. Ok now sharing it out, well you have to enable sharing for people who do not have an account on that machine; (hey, this is a home network) another step. now to add additional drivers (like, for XP but nope, can't do that cause it asks for .inf file and I can't find it 0k didn't really investigate if it was there, but i am fairly sure the lay-person won't find it)
Now, going to the XP machine I point to the windows 7 machine and low and behold it says "driver is not installed on that machine, so browse to it on your own machine", but then it is nowhere to be found on the machine (or I couldn't find the driver as I checked every $win inf$ file there was)...and also guess what, you won't find that HPA driver anywhere at HP.com either.
So... I installed a 5800 series printer on my xp machine, pointed it to the local port and said just install the driver even though the it cannot find the printer. Then I went to the newly created printer and changed the port; created new port and called it \\(windows7machine)\(sharedprintername)
Now I can print to the shared printer on the Windows 7 machine.
Anybody got a better way?
