TCP/Socket network printers are not connected to a single computer but to Internet outlet. They use TCP protocol to transfer PostScript command. So, they are working on industrial standards and do not require you to have special OS. Gnome desktop on Linux provides an easy way to connect them.
Click "System" -> "Administrator" -> "Printing".
Double click "New Printer".
Then select "Network Printer", "TCP/Socket" and enter the domain name or IP address of the printer. The default port is 9100.
On the next page, select proper manufacture, model and driver. You are recommended to use Postscript.
Then, follow instructions to finish.
