description
Creates an internal memory buffer to store portrait text and barcodes. The size of the buffer is determined by n, the number of characters per line. The n parameter is converted internally to millimeters so new line lengths can be automatically calculated in the event a font change takes place. The conversion to millimeters is done by multiplying the value of n by the width of whatever font is currently set when the GS u command is sent.
This command may be used in conjunction with the GS T command to determine where, if at all, text wraps to the next line.
This command is similar to the GS t command.
