paper path. The entire route that forms travel while they are being processed. The paper path usually begins where
the forms are loaded and ends at the stacker.
parallel port. An access point through which a computer transmits or receives data that consists of several bits sent
simultaneously on separate wires.
PCL5e. Hewlett-Packard's Printer Command Language, a data stream used for printing.
pel (picture element). (1) An element of a raster pattern; a point where a toned area on the photoconductor may
appear. (2) On an all-points-addressable output medium, each pel is an addressable unit. On a row-column
addressable output medium, the only pel addressable is the beginning of a character cell.
physical page. The form on which the printer is printing, such as an 8-1/2 x 11-inch sheet of paper. See also page.
Contrast with logical page.
pitch. A unit of measurement for the width of a printed character. It identifies the number of graphic characters per
inch; for example, 10-pitch has ten graphic characters per inch. Uniformly spaced fonts are measured in pitches.
Contrast with point.
point. A unit of measurement for describing type sizes. There are 12 points to a pica, about 72 points to an inch.
point of origin. The location of the first print position on a logical page. The point of origin is usually stated in terms
of X and Y coordinates. The point of origin used by a printer can be affected by factors such as printable area and
forms orientation.
portrait orientation. Pertaining to a display or hard copy with greater height than width. Contrast with landscape
orientation.
PostScript. (1) A page description language with interactive graphics capabilities that was developed by Adobe
Systems, Inc. (2) An interpretive programming language that describes the appearance of text, graphical shapes, and
sampled images on a printed page by defining a print file format that is the interface between document composition
applications and raster printing devices.
preprinted form. A sheet of forms containing a preprinted design of constant data with which variable data can be
combined. See also forms.
Print-Error Marker (PEM). Small, black, rectangular marks that indicate incorrectly placed data in the valid printable
area.
print position. The physical positions of the characters constituting a print line relative to the form.
print quality. The quality of printed output relative to existing standards and in comparison with jobs printed earlier.
print surface. The side of a form that receives the printed image.
raster. (1) In computer graphics, a predetermined pattern of lines that provides uniform coverage of a display space.
(2) The coordinate grid that divides the display area of a display device. (3) In the InfoPrint 20, an on/off pattern of
electrostatic images produced by the laser print head under control of the character generator.
raster font. A font in which each character is defined by a raster bitmap.
raster pattern. A series of picture elements (pels) arranged in scan lines to form an image.
raster scan. A technique of generating or recording the elements of an image by a line-by-line sweep across the
entire output medium.
resident font. Those font data sets that are resident within the printer. They usually reside on the printer disk media
(diskette or hard disk). These font sets are usually commonly used fonts. Having them resident reduces font load time.
These fonts may also be used during offline testing of the printer.
scalable font. A font whose graphic characters are represented by mathematical equations and can be sized to
different heights.
SCS. See SNA character string.
