Printek Emulation
The graphic data is sent using Graphic commands as described on page 16. The image may consist of up to
2,436 graphic lines. The loading process will terminate when 2,436 lines have been received, or upon receipt
of the Store Graphic Image command.
Example: This escape sequence specifies that the following graphic command(s) will define graphic image
“A”.
Escape Sequence: ESC L G A Graphics Data
Hexadecimal: 1B 4C 47 41 Graphic commands as described on page 16.
Note: This command may be used to store graphic images that can later be recalled and printed using O’Neil
Emulation Easy Print commands. The name used in the Easy Print command would be “LOGOn”, or
“LOGOA” for the above example.
Store Graphic Image ESC L G DEL
This command terminates the Load Graphic Image mode and causes the graphic image to be stored in the
printer’s Flash memory.
After this command is received, the printer will transmit a “D” (Hexadecimal 44) and begin saving the image.
Once the image is stored, the printer will transmit a an Exclamation Point (“!”, Hexadecimal 21). The image
may now be printed using the Print Graphic Image command.
Caution: The printer power must remain on throughout this entire process.
Escape Sequence: ESC L G DEL
Hexadecimal: 1B 4C 47 FF
Print Graphic Image ESC L g n
This command will print a graphic image that was previously stored using the Load Graphic Image command.
Example: The following escape sequence will print the graphic logo stored in location zero.
Escape Sequence: ESC L g A
Hexadecimal: 1B 4C 67 41
Black Mark Sensing
The MtP400 printers can print on preprinted forms on roll media by using a “black mark” to sense the
beginning of each form. The black mark is located on the form in a position where the printer’s paper out
sensor can be used to detect its presence. Additionally, the MtP400 LP model is capable of sensing a black
mark on the back side of the form and for sensing the gap between labels. The recommended position for the
black mark is described below.
Black Mark Requirements
The position described below is designed to be used when seeking a Black Mark at the beginning of a print job.
This position and will require little or no reverse paper motion resulting in the fastest throughput and best
printing alignment, and reduces the potential for paper jams. However, the vertical position of the Black Mark
is entirely dependant on the application program that is controlling the printer.
