IP Printing to Network Printers
The iSeries has a built-in print driver for direct IP printing to HP PCL/PJL compatible network
printers. Automatic conversion of SNA Character String (SCS) and Advanced Function
Printing (APF) print data into HP Printer Control Language (PCL) is done using the iSeries
Host Print Transforms. In addition to direct support of a variety of network printers from HP,
IBM and other vendors, the PJL support also can monitor status from those printers. Printing
for TCP/IP networks can also be implemented using the Printer Passthru function available in
Client Access. See “Telnet client and server” on page 563 for more details.
Internet Printing Server for iSeries
The Internet Printing Protocol (IPP) defines an industry-standard method of delivering print
jobs using Internet technologies providing for Web-enabled print around the world. The IPP
was developed by the Printer Working Group, a consortium of all major companies involved in
network printing. IPP is fast becoming the single standard interface for printing on the
Internet, with broad vendor implementation and customer acceptance.
The IPP Server for iSeries, included in
OS/400, provides an IPP Version 1.0
compatible print server for the iSeries. The
IPP Server for iSeries allows anyone
working remotely, to submit and manage
print jobs on a distant iSeries. IPP is built
on top of HTTP, which in turn, runs over
TCP/IP. Customers can now use the same
print solution on local area networks,
intranets, and the Internet. The same
process used to send a print document to
the department printer down the hall can
be used to send the document to the
corporate printer across the country.
The IPP Server for iSeries provides security features for user authentication and encryption
of print jobs using Secure Sockets Layer 3 (SSL).
Line Printer Requester (LPR) and Line Printer Daemon (LPD)
Line Printer Requester (LPR) and Line Printer Daemon (LPD) allow users to print a spooled
file from any system in a TCP/IP network. LPR is the sending or client portion of the spooled
file transfer. LPD is the receiving or server portion of the spooled file transfer. On the iSeries,
the Send TCP/IP Spooled File (SNDTCPSPLF) CL command allows you to print a spooled
file on a remote system and specify appropriate printing operations. You can send files to
iSeries servers and non-iSeries systems.
