We are NOT using pmOriginalSize. We are using pmSpecificWidthAndHeight. We call PrintMode after we have set the orientation on the printer, but it seems Printmode is randomly setting the orientation to Portrait or Landscape. We are adding a statement to SetPrintMode that says:

if(PrintMode = pmSpecificWidthAndHeight) AND (UsePrintJob)

so that SetPrintMode will not set the orientation on the printer. We have UsePrintJob set to false. We hope this fixes our current problem.
