what’s the syntax to represent a printer in fqdn style?

I am trying to send a print command to a printer via telnet.

Normally I would send it to telnet://printer125:9100

but I am not able to access the printer directly. server admin indicated that I need to go though the print server. server1.domain.comprinter125

what is the correct syntax to reach printer printer125 on server1.domain.com

is it something like this?

telnet://server1.domain.com:9100/printer125
