Exception of during print of documents having pages with different orientation

[Вячеслав Павлов]

We need to print documents which have pages with different orientation. But below area of code doesn’t allow to do it:

procedure TPrinterLinux.SetOrientation(Value: TPrinterOrientation);
begin
inherited; ← it invoke CheckPrinting(False) and raise exception RaiseError(SPrinting).
FmuxSetOrientation(Integer(Value));
end;
