Psf/400 - New With V5R1 - IBM i series Handbook

every step of the way. When an OS/400 writer is started to an IPDS printer, PSF/400 provides
these services:
• Establish communication and query printer capabilities and status
• Manage overlay, image, and font resources required in the printer
• Transform the iSeries spooled file (from AFP, IPDS, or SCS) into a printer-specific
IPDS data stream
• Manage the print process, including handling error conditions and managing error
recovery down to the page level
The net effect of this level of print management is to ensure each page of each spooled file is
printed completely and accurately. PSF/400 enables all parameters of the printer file and all
DDS print keywords (subject to printer limitations). IPDS printing takes on added significance
across the network. TCP/IP print support is more limited than traditional iSeries print
management. SNDNETSPLF (LPR in TCP/IP terminology) simply sends a spooled file with
limited instructions and no feed-back as to whether it was received and printed correctly.
Applying IPDS to a TCP/IP network restores the same level of print support (as described
above) as twinax-connected printers. This includes sending standard SCS spooled files
across the network.
To create an Intelligent Printer Data Stream (IPDS) printer on the system, you must (after
specifying the device type as IPDS) specify AFP(*YES) in the printer device description. Any
printer defined as Type(*IPDS) and AFP(*YES) needs the Print Services Facility (PSF) of
OS/400. Twinaxial connected IPDS printers can be defined as AFP(*NO) and, therefore, do
not require PSF. Regardless of connection type, AFP (*NO) means that there will be no AFP
resource management for fonts, images, or overlays. All IP-connected IPDS printers must be
configured with AFP(*YES) and therefore require PSF/400.
The PSF feature of OS/400 required is based on the speed of the fastest printer measured in
Impressions per minute (IPM), not by your CPU size. The number of printers does not matter.
The speed of the fastest printer does.

• Automatic e-mail of output (PDF) function
Infoprint Server provides the PDF server functions and handles the transformation of
iSeries output to PDF format. The start page group and end page group keywords in DDS
(OS/400) provide the triggers for PDF segmentation (multiple PDF files from one input
print file). The multiple PDF files can be e-mailed to different IDs. User exits provide for
customization and address book lookup.
• Expanded page definitions for output formatting
