I just found out that Apple has released a Rendezvous Services bundle for Windows. I had a chance to see if I could use it (I do have one Windows XP system here at Thistle Dew Media Unlimited). So I installed it and set it to browse the network: nothing doing. I did a little Google-aided research and found some information on Windows’ expectation for a listener on port 9100, the port used by HP JetDirect print servers. So I added this:
red:pdl
_pdl-datastream._tcp.
/printers/lp
9100
to /etc/rendezvous.conf, bounced the mdns service, and hey presto. It worked.
This is what you would see in Rendezvous Browser, a really useful tool [download]: 
And to my amazement, it worked first time. I printed a page from FireFox in XP and the printer kicked it right out. (I’m still amazed at CUPS on a daily basis: how it makes a cheap non-PostScript printer into one capable of rendering 600×600 dpi output with a minimum of hassle is beyond cool.)
