System-Level Commands

STX I Image Downloading

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 M for more information. To print an image, see Generating Label Formats.

Note: The native format for storing downloaded PCX and BMP images is RLE-2. This results in a better compression ratio for gray-scale images and for images with very large areas with either black or white, effectively resulting in more module space for downloaded images.

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 A.
