http://www.crowsons.com/puters -> C500.php
The C500n is a colour laser printer from Lexmark.
Telnet
When configuring the C500 using Telnet you need to use the following user:
sysadm
This user does not have a password.
FTP
When printing to the C500 using FTP you need to use the following user:
port1
This user does not have a password.
Currently I have not managed to get ftp or lpd printing working on the C500n.
