I've just had to do the same thing at home - I found the same webpage you did, followed it, and found the classes bit it was completely unnecessary.

Basically, W2K and above support IPP, as does CUPS. The tricky bit is knowing the URL to use for the printer. The answer? In my case:

http://<hostname>:631/printers/<printername>

Note that ipp://... doesn't work.

The bit that held me up for an hour was I'd subconciously added an extra "/" at the end of the URL. Windows just kept choking on this. I realised my mistake when I was browsing the CUPS web interface, and noticed that the printer status page for my printer was

http://<hostname>:631/printers/<printername>/

Given that this clearly resulted in a webpage being returned, it couldn't possibly be a termination point for IPP, right? Checking the CUPS IPP documentation showed they didn't use a trailing "/", so I tried it without, and it worked.

However, I did have to manually edit the CUPS config to allow other hosts on my subnet to access CUPS, and I have to largely agree with ESRs comments on a general level. I use Linux almost exclusively at home, but wouldn't dream of getting my extended family to change - I spend enough time sorting out their Windows problems. Until I can take them through all the configuration issues they have over a phone (and that means using a GUI, not an editor) Linux ain't gonna happen with them.
