[cups.general] Printing from remote clients

[Sam Leathers]

I haven't been able to test from a linux machine because there is a live 
cups server running on this machine on port 631, and I haven't figure 
out how to tell client.conf to use a nonstandard port when connecting, 
but anyways, that isn't the immediate problem.

I get the errors  below in my error_log when I try to print from a 
remote machine using lpr (machine happens to be mac os x). I'm assuming 
by the nature of the errors I have something wrong in cupsd.conf.

Thankyou,

Sam
