System-Level Command Functions
Class Series Programmer’s Manual 20
STX I Input Image Data
This command must precede image downloading from a host computer 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 O for more information. To print an
image, see Generating Label Formats.
A-Class (and H–Class models with a large display): 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.
 Note: 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.

Sample: <SOH>D
<STX>IDpTest <CR>
data...data <CR>
The sample instructs the printer to (1) receive an 8-bit PCX image sent by the host in an 8-bit data
format, (2) name the image ‘Test’, and (3) store it in memory module D (with a .dim file extension).
