Chapter 5 Printer Commands
428TC Operator’s Manual - 880041-0141 5-35
begin printing as soon as the image has completed reprocessing plus approximately 10
msecs. If sufficient time is allowed for the reprocessing to complete prior to the next General
Purpose print input, the printer will begin printing almost immediately (~10 msecs).
The time between the completion of printing and when the next label is available to print is a
function of the size of the image being generated. Larger labels will take longer.
The main difference between the two modes is single sync mode prints one label and exits
sync mode. Continuous sync mode allows a user to print as many labels as they want using
the print signal until the abort is received or a paper-out occurs.
^A ^D Command
116 Synchronous Print Mode
0 Exit all sync. modes.
1 Enter single sync. mode.
2 Enter continuous sync. mode.
WARNING! There is NO time-out on this command! Once the printer receives the ^D116
command and is waiting for the PRINT or ABORT pulse, it will wait forever!
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]
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]
