Remote print problem -- LPD, IPP and other standard printer ports

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



I have most ports closed on my router except the obvious (POP, SMTP, 
FTP, Interbase, SQL Server, MySQL and VNC).  Could I have a port closed 
that CUPS needs?  I have identical problems with Linux (RHE) and Mac Tiger.
