Map Page Segment structured field (MPS). The Map
Page Segment structured field identifies the page
segments to be loaded into the printer and to remain in
the printer while the entire print file is printed.
marking. Amethod that refers to the updating of
certain structured fields that identifies a resource for use
by Remote PrintManager or as being printer resident.
maximum speed. The highest speed of which the
printer is capable in characters per second (cps), lines
per minute (lpm), or impressions per minute (ipm), for a
given size sheet.
media destination. The destination to which sheets
are sent as the last step in the print process. Some
printers support several media destinations to allow
options such as print job distribution to one or more
specific destinations, collated copies without having to
send the document to the printer multiple times, and
routing output to a specific destination for security
reasons. Contrast with media source.
media destination by copy. Theability to select the
destination for an individual copy of a sheet. This
function is not supported by PSF.
media origin. The first hardware addressable point on
the physical medium. The point from which the logical
page origin is positioned by the medium map. This point
is represented by Xm=0, Ym=0 in the Xm, Ym coordinate
system. The media origin is defined relative to the top
edge of the medium. Synonymous with medium origin.
media source. The source from which sheets are
obtained for printing. Some printers support several
media sources, so that media with different
characteristics (such as size, color,and type) can be
selected. Contrast with media destination.
media source by copy. Theability to select the
source of the media for each copy of a sheet, when
making multiple copies of a sheet.
medium. The physical material (for example, paper)
on which data is printed. See also form.
medium map. An internal object in a form definition
that controls the modifications to a form, page
placement, and overlays. Synonymous with copy group.
medium origin. Synonym for media origin.
medium overlay. Anelectronic overlay that is invoked
by the medium map of a form definition for printing at a
fixed position on the form. See page overlay.
MICR. See magnetic ink character recognition.
MICR printing. The ability of a printer to either print
with magnetic toner or to allow MICR printing through a
postprocessing device.
microfilm device. An output device that presents a
hardcopy on microfilm.
Mixed Object Document Content Architecture. An
architected, device-independent data stream for
interchanging documents.
mixed-pitch font. Afont that simulates a typographic
font. The characters are in a limited set of pitches; for
example, 10 pitch, 12 pitch, and 15 pitch.
MO:DCA. See Mixed Object Document Content
Architecture.
MO:DCA-P. Printdata that has been composed into
pages. Textformatting programs such as DCF can
produce composed text data consisting entirely of
structured fields.
MOF. Metric-onlyfont.
monospaced font. Afont in which the graphics
characters have a uniform character increment.
Synonymous with uniformly spaced font. Contrast with
proportionally spaced font.
MPS. See Map Page Segment structured field.
Multiple Virtual Storage (MVS). An IBM operating
system running on a S/370 or S/390 processor.
multiple-up. The printing of more than one page of
application data on a single surface of a sheet of paper.
MVS. See Multiple Virtual Storage.
N
N_UP printing. In basic N_UP printing, the dividing of
a side of a sheet into a fixed number of equal-size
partitions. For example, N_UP 4 divides each side of
the sheet into four equal partitions. In enhanced N_UP
printing, the sheet can be divided into 8 partitions,
anywhere on the sheet.
NACK. See negative acknowledgment reply.
narrow forms. Forms that have their longer edges at
the sides and their shorter edges at the top and bottom.
negative acknowledge reply (NACK). Areply from a
printer to a host indicating that an exception has
occurred.
nonimpact printer. Aprinter in which printing is not
the result of mechanical impacts; for example, thermal
printers, electrostatic printers, and photographic printers.
(I) (A) Contrast with impact printer.
normal duplex printing. Printing on both sides of the
paper so that the sheets can be bound on the long
edge of the paper.Contrast with simplex printing. See
also tumble duplex printing.
