General Description
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.
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.

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.
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.)
