I'm trying to get iPrint to work thru our Border proxy. IE and the
iPrint client are set to use the proxy. I can hit the iPrint page and
see all printers, install the client, view job lists, etc. But it will
not print. Just hangs the browser for a few seconds then nothing. No
error at all. If I drop the firewall and remove the proxy setting from
the iPrint client, it works. The proxy on the BM box has ACL's to allow
all port traffic and http traffic.

Any ideas?
iprint client 3.05
