Hi Michael,

This is exactly the sort of thing I was looking for.  Thanks!

I tried it now with the mentioned printer but it returned "socket"
regardless.  Ok, then I went to another machine (that had like 14
printers configured via IPP).  I just did "grep ipp
/etc/cups/printers.conf" and scanned all of those.  To my surprise they
all returned "socket://" as well (no mention of IPP).   Have you seen
this kind of beavior before?  I guess I must fire up snmpwalk :)

I'm glad to know that there's some standardization in that part.

Thanks!
