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 InfoPrint 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.
