SOFTWARE COMPONENTS
Resident languages
There are three languages resident on the LPS: Forms Description
Language (FDL), Interpress, and Print Description Language
(PDL).
FDL
FDL is an LPS resident language you use to design electronic
forms. You can include logos, signature fonts, and shading in
the forms you create. Source and object form libraries are stored
on the system disks.
Reference
Refer to the Xerox Laser Printing System Forms Creation Guide
for more information.
Interpress
Interpress is a PDL capable of describing any two-dimensional
image intended for a raster device such as an LPS. This language
describes the data you create on the page; it is not a page
composition language.
You can use Interpress to describe vector graphics (sometimes
referred to as line art), contour fonts, and pixel arrays. Interpress
also includes job management features such as paper tray
selection, output offsetting, stock selection, copy count, and
page selection. You can create an Interpress master at the host
computer system or at a workstation and transfer it to the LPS.
PDL
PDL is a resident language that you use to describe the input,
logical processing, and output requirements of your print job.

Language (PDL) Reference for more information.
Host software
There are several software packages which are resident on the
host computer system. These software packages enhance the
functionality of the LPS.
Electronic Printing Image
EPIC is a host-resident software package available on IBM MVS or
Construction (EPIC)
VM/CMS, which translates computer-generated text and graphics
into high-quality images you can print on an LPS.
A version of EPIC which is independent of the host computer
system is also available for non-IBM users. Refer to EPIC
documentation for more information. The GHO option is
required on the 4050/4450 LPS. The GVG option is required on
the 4090/4650 LPS.
