Printer Commands Chapter 5

^A ^D Command
X 145 List Commands:
This command is used to generate a list of commands containing a brief
description of the LDSI code base that the printer uses. Issuing a ^D145 or
^A0^D145 causes the printer to generate a list of commands supported by the
LDSI code base to communications port.
0 List LDS Commands
1 List current settings
2 List Soft-switch descriptions
X 146 Pre Stock-Out Distance:
This command sets the distance in dots that the PSO option uses to feed the
media when the >INPUT 1< sensor detects an out of media condition. If the
length of the label happens to be larger than the distance from the pre stock
out sensor to the dot row (^D146 command) the printer will not be able to
completely finish printing the last label. Other than this, the operation of the
printer will be the same as above. The printer’s default distance is set to 1800
and issuing a “0” (^A0^D146) will cause the printer to reset to this value. The
maximum setting is 7200 and values above this setting will be ignored.
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]
This format only needs to be sent one time after the unit has powered
on. The >RESTARTED< status message could be used to indicate
when this needs to be sent or simply send it each time a print is
desired.
2. The Host then sends the printer the ^D149 command followed by the
raw image size that has been converted by the bmp2mic rev 1.02 or
later. Please note that the size is only terminated with a [CR] and the
[LF] is not included.
Example: ^D149[CR][LF]size[CR]
