All SureMark printers print the customer receipt using the thermal printhead. For

SureMark printers that include a document insert station, documents are printed

using the impact head. No SureMark printer contains a journal print station.

Thermal printing occurs by placing a heating element against a thermally sensitive

paper. By energizing the elements, dots are formed. Thermal printers print dot rows

horizontally across the page –576 dots make up a single dot row across the paper.

Printing continues row by row until the entire character is formed.

Impact printing utilizes a standard ballistic printhead. Each wire is fired against an

inked ribbon which places a dot on the paper.

SureMark printers contain all the circuitry, processing hardware, and software for

operating a thermal and, except for models TF7 and TM7, an impact printer

mechanism. SureMark printers do not contain a power supply. However,they do

contain voltage conversion circuitry to allow connection to a standard IBM system

interface or to an RS-232 24-volt power supply. (See “Power Requirements”on

page 8 for specific power supply specifications.)

The information in the Document Insert Station column of Table8 on page 78

applies only to SureMark Models TI5 and TG5. There is no document insert station

on models TF7 and TM7.
