Hi Akamol,
You have 2 points of problem. The first is firewalling. As you see in the error message, the requested port is 515, which is under 1024, which is priviledged. The standard RHL is comming with a firewall configured. Into a local network you could live well without it. Disable the firewall of your client and try the command again.
If it doesn't work yet, you have to see the lpd configuration of your client, which is working as a print server to see how enable remote printing. If you need some more help, please post the version of your distribution and what printing subsystem you are using. The most common are lprng and cups.
Have a nice week end!

Akamol,

Two more possible issues:

1. To be able to use a lp queue remotely, you must create a file /etc/hosts.lpd on your box connected to the printer. This file must contain a line for each remote host which submits jobs to this box, like:
+remotehost.mydomain.com

(Perhaps you need to restart the printer on your remote box. I am not sure how to do that, I use CUPS and access the printer thru the web interface, eg. http:/localhost:631)

2. This is a tricky one, and occurs in Debian, not sure about RH. In Debian, the lpd deamon on the printer box is started with the "-s" option. This is checked with the "ps ax | grep lp" command. If "-s" option is active, lpd will NEVER accept any remote jobs! In order to remove this, you should either edit the /etc/init.d/lpd script, or the /etc/default/lpd file (in Debian) and remove the "-s" option.

Good luck
