Memory units (models TN x )
Random access memory (RAM) is used for storing the image data for the thermal
printhead and program code. It is also used for storing incoming data from the
communication port.
For TN x model printers, flash memory is used for many purposes, including:
v Character set storage (80 KB)
v
Personalized message storage (8 KB)
v Logo or APA message storage (64 KB)
v
Program code and resident character sets (256 KB)
Personalized messages are those messages that are printed on each receipt in a
POS environment. Storing these messages in the flash memory greatly reduces the
data transmission time to the printer and the processing time of that data by the
microprocessor. This is also true of graphics or APA messages, which require a
significant amount of transmission and processing time.
Immediate commands
The SureMark printer has 16 KB of memory on Models TN x to store incoming
commands and data.
Most commands will be received and then executed sequentially. However, several
commands execute immediately upon receipt. These commands are:
v Download Graphics
v Predefine Messages
v Download User-Defined Characters
v Extended Address Command-Request Printer ID
v Real-Time Requests
