TCP/IP Print Enabler (TPE)

Product Overview

TCP/IP Print Enabler (TPE) enables an enterprise server to share printers in a TCP/IP network, thus helping you to reduce costs and improve productivity.

TPE supports inbound and outbound printing from an enterprise server. Outbound printing enables enterprise server print requests to print on printers directly connected to a TCP/IP network or on printers connected to print servers that use either the Berkeley Systems Development (BSD) lpr/lpd (line printer/line printer daemon) protocol or the rsh (remote shell) protocol.

The inbound printing capability enables printer files generated on systems that support the lpr/lpd protocol, such as PCs and UNIX systems, to be printed on printers attached to enterprise server systems.

The following figure shows an example of a TCP/IP Print Enabler configuration.

General Features

TPE enables you to print from an enterprise server on a variety of printers connected directly or indirectly across a TCP/IP network.

Printers Connected Directly to TCP/IP Networks

When you choose this method, you do not need to purchase and administer a print server. Thus, you experience a reduction in cost and an increase in productivity. Additionally, you can attach multiple printers directly to a TCP/IP network by purchasing an external network interface adapter.

The TPE can direct print requests from the Print System to printers with network interface cards (NICs) that support the following protocols:

  • BSD lpr/lpd protocol

  • TCP/IP protocol

The TPE can also direct print requests from the Remote Print System and Transaction Server direct-window programs to printers with NICs that support the TCP/IP protocol.

TCP/IP Print Servers

The TPE can direct print requests from the Print System to TCP/IP print servers that support the following protocols:

  • BSD lpr/lpd protocol

  • rsh protocol

You can also route print requests from a UNIX system or a PC to a ClearPath printer. The enterprise server TCP/IP Print Server supports print requests to enterprise server printers from remote clients by using the lpr/lpd protocol.
