STX G Print Last Label Format
This command prints a previously formatted label and restarts a canceled batch job
following the last processed label. This is used when there is a label format in the buffer.
The
<STX>E
command is used to enter the quantity. (Without the
<STX>E
command, one
label will print.)
Syntax:
<STX>G
STX I Input Image Data
This command must precede image downloading from the host to the printer. The data
that immediately follows the command string will be image data. If any of the 8-bit
input formats are to be used, it is necessary to disable the Immediate Command
interpreter by executing an
<SOH>D
command before issuing the
<STX>I
command. See
Appendix N for more information. To print an image, refer to Generating Label Formats.
A-Class (and large display H–Class models): A “ready mode” logo image can be
input using this command. The image must be stored on a Flash module. The image
name must be “
logolab
” (lowercase only) in the following DPL command. Also, printer
power must be cycled for the new image to appear. The available display area is 312
pixels wide by 94 pixels high. Images larger than this specified width or height will be
clipped along the right and/or bottom edges.

The native format for storing downloaded PCX and BMP images is RLE-2, which results
in a better compression ratio for less module space usage when downloading gray-scale
images and images with large black or white areas.
