SOFTWARE COMPONENTS
Host Forms Description Language HFDL is a host-resident forms design software package available
(HFDL) on IBM MVS or VM, which allows you to create, change, and
merge forms with data at the host computer system for printing.
Reference Refer to the Xerox Laser Printing System Forms Creation Guide
for more information.
Xerox Printer Access Facility (XPAF) XPAF enhances the capabilities and use of your LPS in an IBM
MVS/XA environment. For example, it allows you to change
printer destinations without restructuring the datastream. XPAF
accepts numerous types of datastreams, transforms and
conditions them, and then sends them to the printer you select.
To users of IBM Advanced Function Printing (AFP), XPAF appears
to be an extension of the IBM product.
Operating system
The LPS Operating System Software (OSS) is a set of programs
which allow the printing system to manage its own resources.
Xerox distributes new versions of the OSS on magnetic tapes or
floppy disks. These release media contain the following
programs:
•
New system files
•
System generation processor program you use to load and
configure new system files onto system disks
•
Concatenated version of the system files and system
generation processor you use to perform an online system
generation for your tape system
•
Patch files you use to modify the new system files for optimal
performance.
System generation
System generation, or sysgen, is the process you use to install,
upgrade or modify the OSS. There are three types of sysgens
that you can perform: mini, update, or full. Table 3-2 provides an
overview of sysgen types.
Reference Refer to the Xerox 4050/4090/4450/4650 LPS System
Administration Guide for complete instructions for each of these
sysgens.
