P-Series Printer Emulation: This code system was developed especially for line
matrix printers. As line matrix printers became more sophisticated, this code
system kept pace by adding codes that fully utilized line matrix printer
capabilities.
IMPORTANT: This emulation appears as “P-Series” on the operator panel.
P-Series XQ Variant Printer Emulation
This code system was devised for a series of printers manufactured between 1974
and 1991, that are no longer available.
IMPORTANT: This emulation appears as “P-Series XQ” on the operator panel.
Serial Matrix Printer Emulation
This printer emulation is very similar to the code systems used by an IBM
Graphics Printer, but incorporates several systems into one emulation. This
emulation enables a line matrix printer to print files coded for a serial matrix
printer, and is sometimes referred to as the Serial Matrix collection.
IMPORTANT: This emulation appears as “Serial Matrix” on the operator panel.
Note:
Serial matrix refers to the way printer characters are formed. A moving
printhead uses pins to form whole characters one at a time and one after the
other. The pins print dots according to programmed matrix patterns. Data is
sent to the printer through either a serial or parallel interface, but the
printhead must receive the data serially to form each character.
An IBM line matrix printer also forms characters with dots in matrix
patterns, but it feeds print data in parallel to many hammers mounted on a
rapidly oscillating shuttle. The hammers fire simultaneously to print entire
lines at a time.
