this is a video showing you how to printer share between windows 7 and windows XP.
please note that in the video a said that there are no other videos on this but since filming this video I think one has popped up, but I dont think it shows how to printer share with 7 and XP, just 7.
Also note that this also applies to windows vista as well its the same as XP so just follow the XP guide for people running vista, I would have shown you how to do it in vista but I dont have vista installed on any machine in my house any more.
Also the error message you get in windows XP, the one I said was really common, only happens on some computer. It really depends on your hardware and network set up ex. (also the . That I put after computer name doesnt make a difference I tried without and still got the same error), its far easier just to browse for it.
Just in case youre interested, saves leaving a comment Ill tell you now, the version of XP Im using is XP 64 bit edition, and the version of windows 7 Im using is windows 7 ultimate, (yeah I know ££££ but its good, and touch wood iv had no problems yet, unlike vista after only 4 hours I was sick of seeing blue).
