Printronix ThermaLine Series - Manual (Page 126)

Commands 4–82
Comments The size and number of raster image logos are bounded by printer memory.
The logo call command in the Create Form mode brings the predefined
logo into a form. The starting row and column parameters refer to the upper
left corner of the logo grid. Once created, the logo is ready to be used in
any form and will print at the size shown.
Raster images may contain data that is interpreted by your host as control
codes. This may affect the way the host sends data to the printer. Consult
your host’s Setup Guide for sending binary data.
Be careful when editing PCX output files because most TEXT editors insert
carriage returns and line feeds. If a PCX file must be edited, use a binary or
hex editor.
