Operating System/400 (5722-SS1)
Network Printing Support
Distributed print support provides a connection to LAN-attached ASCII printers and support
for Advanced Function printers. It also facilitates the distribution of printed output throughout
iSeries networks. The iSeries server provides a seamless path for customers to direct printed
output through an iSeries network and to other print servers. SNA or TCP/IP protocols
(LPR/LPD) can be used to transport the spool file and its attributes to the remote system.
This integrated operating system function supports printing of text, images, graphics,
barcodes, electronic forms, multiple fonts, logos, signatures, and more. As a result, it
provides the basis for business solutions like business reports, preprinted forms, customer
statements and invoices, and letters. Double Byte Character Set (DBCS) documents that
enable printing of Chinese, Korean, Japanese, or Thai characters are also supported.
OS/400 supports IBM and non-IBM printers, which vary in price, function, speed, and use.
Host Print Transform
Most printers are designed to work with a specific data stream, so OS/400 includes a function
to automatically transform the program-generated data stream to that required by the printer
to which it is sent. It is not necessary for the application to generate the correct data stream;
the system will automatically transform it as necessary at print time. Customization objects
are provided for over 125 popular IBM and non-IBM ASCII printers, such as Hewlett Packard
PCL, Lexmark PPDS, and HP LaserJet TIFF Packbit. An API brings the capabilities of Host
Print Transform to the iSeries application developer.
Printer Load Balancing
Local and remote output queues permit more than one active writer, allowing spooled output
on one output queue to be printed on multiple printers. In addition, a limit can be placed on
the size of spooled files printed during a specified time period. With these features, large print
jobs can be deferred to print during non-peak hours.

Communication and Networking

Connectivity to Remote Devices, Systems and Networks
OS/400 offers many integrated capabilities and functions that enable communications with a
variety of IBM and non-IBM systems, either in batch or interactive modes. This integrated
connectivity function provides customer solutions by enhancing the integration of business
systems. Worldwide standard TCP/IP or the traditional SNA hierarchy, as well as SNA peer
networks and SAA standards, are supported and offer the user the greatest flexibility possible
in network design now and in the future.
