General description
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.)
Specifications
The information in the Document Insert Station column of Table 5 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.
