The command above is used to control character height, width and line spacing, where cno> and cnl> (low byte first) ate used to supply the number of subsequent data bytes (1 or 2). The effect of the two data bytes (ur2> and <n3>) is determined as follows:

Any superscript/subscript or condensed mode print settings previously selected will be cancelled. but if double-height printing is cancelled, the printer will return to superscript/subscript or condensed mode printing, if these were selected previously. Any previous commands for vertical character enlargement are cancelled by this command. If double-height and normal-sized characters are printed in the same line, then the printing will be aligned along the bottom of the normal-sized characters.
