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

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

using the impact head.

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 print head. 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 TF6 and TM6, 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 EIA-232 24 V power supply. (See “Power requirements” on page

12 for specific power supply specifications.)

The information in the Document Insert Station column of Table5 on page 88

applies only to SureMark Models TI1, TI2, TI3, TI4, TI8, TI9, TG3, TG4, TG8, and

TG9. There is no document insert station on Models TF6 and TM6.
