    additional <syn>, <etb>, or <esc> characters will be treated as print line data, representing pixels to print, until the required number of bytes for the print line are received. The character received by the printer after the last data character should be an <esc> character, denoting a command sequence, or a <syn>...

    Printer Commands All LabelWriter 400 series printers implement the same basic commands. The LabelWriter Twin Turbo printer implements one additional command, the Roll Selection command, and the LabelWriter Duo printer implements an additional, but similar, set of commands that are specific to printing on continuous-length tapes (see Appendix B).
