OK - that seemed to work. I've checked via properties on the PC to which the printer concerned is hardwired that all was well and then fired up the netbook now safely home from a hard day's studies. It had me fooled at first because when I asked it to browse for the printer, it came up with the name of the PC which I eventually realised you have to click on to get the printer itself.
So let's hope that 2xlaptops, 2xi-touches, a remote PC and a router don't blow the main PC's mind!
Thanks MJ
