[cups] Network printing problem solved

[Vince Radice]

Hello,

     I had been having trouble printing to my wife's printer.  We are on 
the same LAN and cups found the printer but I could not print to it.  
After a lot of searching I never found anything in the internet.  After 
much looking through cups error_log. I found a message that Host was 
down.  The host was up which led me to try something else.  I went to 
the firewall and opened port 631 to the 4 options (tcp,udp, dccp, 
sctp).  I don't know which one worked but one of them did work and I am 
able to print.

     Is it possible to get the cups doc updated when having network 
issues to check the firewall setting to see if 631 is open.  Also 
indicate which option should be used.

Thank you,

Vincent Radice
