Yes it's doable and yes it works (with one rather large qualifier.......)

With v1.3 or v1.4 onwards (I'm not sure which supports raw IP, but I'm sure Paul
Anderson will be able to state that without a problem) you can initialize the
queue on "IP_RawTCP/www.xxx.yyy.zzz:9100" for a JetDirect card and it's quite
happy to print.

The only thing I know of to watch _very_ carefully is the version of the IP
stack you use.  UCX v4.2 Eco 1 and onwards should be OK but v4.1 didn't seem to
get on with DCPS v1.4 very well and resulted in quite a few crashes and hangs of
the node that handled our printer queues.  I also spoke to someone at Eureka98
in Paris and they'd had similar problems with Multinet IIRC (it certainly wasn't
UCX anyway so you can't say "well that's UCX for you - go and buy Multinet" :-P
)

For PrintServer 17s you need to use "IP_CPAP/www.xxx.yyy.zzz", although you
probably aren't interested in that.  There's no port specification required.
