Answer 1

procedure SetPaperHeight(Value:integer); //设置纸张高度-单位：mmvar Device : array[0..255] of char; Driver : array[0..255] of char; Port : array[0..255] of char; hDMode : THandle; PDMode : PDEVMODE;begin if Value < 90 then Value := 90; //自定义纸张最小高度127mm if Value > 432 then Value := 432; //自定义纸张最大高度432mm Printer.PrinterIndex := Printer.PrinterIndex; Printer.GetPrinter(Device, Driver, Port, hDMode); if hDMode <> 0 then begin pDMode := GlobalLock(hDMode); if pDMode <> nil then begin pDMode^.dmFields := pDMode^.dmFields or DM_PAPERSIZE or DM_PAPERLENGTH; pDMode^.dmPaperSize := DMPAPER_USER; pDMode^.dmPaperLength := Value * 10; pDMode^.dmFields := pDMode^.dmFields or DMBIN_MANUAL; pDMode^.dmDefaultSource := DMBIN_MANUAL; GlobalUnlock(hDMode); end; end; Printer.PrinterIndex := Printer.PrinterIndex;end;
