represents the desired printed pattern. All
the bits of received characters are printed on
the same line.
Text and Data mode enrichment (ESC '{' n) and vertical lengthening mode
(ESC 'w' n) only have an effect in graphic mode. In Text mode, the line is
printed from left to right with the higher weight’s bits to the far left. In Data
mode, the line is printed from right to left with the higher weight’s bits to the
far right. Characters and graphics cannot be printed on the same line.
The graphic data transmission can be transmitted non-compressed or using
tiff4 pack-bits compression mode (see ESC 'm' command).
