  • Page 38 BD2-1220/1221 User’s Manual APPENDIX 1. DESCRIPTION OF PAGE MODE The control board has two print modes: STANDARD and PAGE. In STANDARD MODE, the control board prints or feeds paper each time it receives a print or paper feed command. In PAGE MODE, when the control board receives print commands and/or form feed commands, it simply forwards them to the specified print area of memory.
  • Page 39 BD2-1220/1221 User’s Manual Print data is mapped in the print area as follows: (1) The print area is set by ESC+W. When the control board has finished all of the print and paper feed actions specified before receiving an ESC+W, the ESC+W sets the left end (As viewed facing the control board) as the start point (x0, y0) of the print area.
