printer's memory in which data is stored, control codes or download char-
acters are to be printed. RAM is cleared when the printer is turned off.
ROM:
ROM is an acronym for "Read Only Memory". It is the part of the printer's
memory in which predefined characters and operating information for the
printer are stored. ROM is not cleared when the printer is turned off.
Self test:
Self test is a method for testing the operation of the printer. (1& P.27)
Shielded Cable:
Shielded cable is a cable wrapped with a special metal around its wires.
This guards against radio interference.
String concatenation:
This is the joining of two or more bytes of data into a single command.
Super Quiet mode:
Super Quiet mode is a helpful feature which reduces printing noise.
Unidirectional printing:
The printer prints left-to-right only. Printing speed is slow compared with
bidirectional printing. This print method permits better vertical alignment.
