>Decimal 27 112 m t1 t2

If m is out of range, this command is canceled and the following data is processed as normal data.

If t2 < t1, the OFF time is equal to the ON time.

For starters, try

SET PRINTER TO LPT1:
SET PRINTER ON
??? CHR(27)+"p"             && Esc p
....
SET PRINTER OFF
SET PRINTER TO
