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.
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.)
Specifications
The information in the Document Insert Station column of Table 8 on page 78
applies only to SureMark Models TI5 and TG5. There is no document insert station
on models TF7 and TM7.
