^A ^D Command
X 116 Synchronous Print Mode
0 Exit all sync modes
1 Enter single sync Mode
While in this mode, the printer will render the format and wait for the print
pulse. When the print pulse is detected, the printer will print immediately and
then exit the sync mode. The printer will respond to normal communication
while in this mode.
2 Enter continuous sync mode
While in this modem, the printer will render the format and wait for the print
pulse. When the print pulse is detected, the printer will print. If the pulse is
detected a second time, the printer will re-render the image and print again.
The Test Pattern and Reset signals do not function while in this mode. The
exit this mode, select the Abort signal and then the Reset signal will function.
While in this mode, the printer will not respond to normal communication.
3 Enter Rapid fire continuous sync mode
While in this modem, the printer will render the format and wait for the print
pulse. When the print pulse is detected, the printer will print but it will not clear
the print buffer so will print again as soon as the print signal is detected. The
Test Pattern and Reset signals do not function while in this mode. The exit
this mode, select the Abort signal and then the Reset signal will function.

succession and then stop. To exit this mode, the Restart signal should be
used as the Abort signal is ignored.
5.4.2 USB Image Print Mode
149 USB Image Print Mode:
This command controls an image print mode protocol that is used with the
USB port to shift images to the printhead at fast baud rates. This mode
requires that the bmp2mic rev 1.02 or later be used to convert the 1 bit
monochrome bitmap image to be printed. This mode basically shifts data
directly to the printhead and does not use the normal LDS command protocol.
This mode also uses additional baud rates for higher speed image printing.
Protocol:
1. The HOST sends a format to the printer that identifies the media
being used:
Example: ^D57[CR][LF]
1,1280,940,,,3,0,1[CR][LF]
^D56[CR][LF]
