Miscellaneous printing options.

Pascal
property PrintOptions: byte;
C++
__property byte PrintOptions;
Remarks

A lot of simple printing options are defined inside this property as bits inside the number. You can use the following constants or'ed together to set the options:: 

 

  fpo_LeftToRight = $01; //Print over, then down
  fpo_Orientation = $02; //0= landscape, 1=portrait
  fpo_NoPls = $04; //if 1, then PaperSize, Scale, Res, VRes, Copies, and Landscape data have not been obtained from the printer, so they are not valid.
  fpo_NoColor = $08; //1= Black and white
  fpo_Draft = $10; //1= Draft quality
  fpo_Notes = $20; //1= Print Notes
  fpo_NoOrient = $40; //1=orientation not set
  fpo_UsePage = $80; //1=use custom starting page number.
Example

To set the printing orientation to landscape or portrait, you can use the following code: 

if Landscape then
begin
   Xls.PrintOptions := TPrintOptions(integer(Xls.PrintOptions) and (not (integer(TPrintOptions.Orientation) or integer(TPrintOptions.NoPls)));
end
else
begin
   //ALWAYS SET NOPLS TO 0 BEFORE CHANGING THE OTHER OPTIONS.
   Xls.PrintOptions := TPrintOptions(integer(Xls.PrintOptions) and (not integer(TPrintOptions.NoPls)));
   Xls.PrintOptions := TPrintOptions(integer(Xls.PrintOptions) or integer(TPrintOptions.Orientation));
 end;
