xvii About this manual
Terminology
Specific terms are explained as they are introduced. However, the following general
terms are used throughout:
•
PostScript (PS)
— A computer language designed as a page description language.
The EX7750 uses this language to image the page and communicate with
applications and the printer.
The term “PostScript” can also be used to refer to PDF data jobs. PDF is a
structured form of PostScript that provides the ability to preview, scale, and reorder
pages. Where applicable, the term “PDF” is specifically used to refer to PDF data
or jobs.
•
Printer Control Language (PCL)
—A computer language designed as a page
description language. The EX7750 uses this language to image the page, and
communicate with applications and the printer.
•
Job
— A file consisting of PostScript or PCL commands and comments that describe
the graphics, sampled images, and text that should appear on each page of a
document, and the printer options that should be used in printing, such as media or
finishing options.
•
Spool
—Write to a disk. Used in this manual to refer to a PostScript or PCL print job
saved to the EX7750 hard disk drive in preparation for processing and printing.
•
RIP
—Acronym for raster image processing, which changes PostScript or PCL
commands into descriptions of each mark on a page. In common use as a noun, a
“raster image processor” (RIP) is the computer processor that performs this function.
The EX7750 RIP changes text and graphics commands in PostScript or PCL into
specifications for each dot of toner deposited on a page by the printer.
•
Process
—The term “process” is used interchangeably with the term “RIP” in this
manual to refer to raster image processing.
•
Print
—The task of rendering, or imaging, a page or job on a print device.
These concepts explain how the EX7750 and the printer work together as a powerful
printing system.
