Once you've set the stops, each time you issue a VT command, the printposition will move down to the next stop position.Parameters n1 through nkThese parameters designate the individual stops. In the IBM emulation, you can set up to 64stops (n 1 through n64 ). In the Epson emulation, you can set up to 16 stops. In both emulations,the value of each n can be any whole number from 1 to 255 (0 to 255 for Models ML390T andML391T), designating how many lines to skip down to that tab stop. You must enter the stopsin increasing order (n 1 > n 2 > n 3 , etc.), and end the series with the NUL character.Clear Vertical Tabs Command (IBM/E) ML320 E/I, ML321 E/I ML320 Turbo, ML321 Turbo ML520, ML521 ML590, ML591Function IBM Only IBM & EpsonClear Vertical Tabs ASCII: ESC RDec: 27 82Hex: 1B 52ASCII: ESC B NULDec: 27 66 0Hex: 1B 42 00These commands will delete all vertical tab stops. In the IBM emulation, the ESC R commandwill reset the tabs to the default settings.
