[Gambas-user] Ask About POS Programming using Gambas

[jose julio vidal]

Hi!

my code:
  
  ....
  DIM hFile AS File
  DIM txt AS String
  txt=Chr$(&H1B) & "m" & Chr$(49) & Chr$(0) 'corte papel parcial
  TRY hFile = OPEN "/dev/lp0" FOR WRITE
  WRITE #hfile, txt 
  IF ERROR THEN 
    message.Error("No se puede acceder a la Impresora")
  ELSE 
  END IF
  ....

regards
