Title: Obtaining list of paper names and paper sizes.
Question: How to obtain a list of paper names and sizes for current printer?
Answer:
In order to obtain list of paper names and sizes for curent printer you should to call DeviceCapabilities routine. This is an example of listing paper name strings in PaperNames array, paper sizes in PaperSizes array and corresponding paper identifiers in Papers array:
type
TPointArray = array[0..8191] of TPoint;
PPointArray = ^TPointArray;
...
procedure ListPapers;
var
i: integer;
Buffer: array[0..65535] of byte;
PrinterName: PChar;
PaperCount: integer;
PaperSizeArray: PPointArray;
PaperNames: array of string;
PaperSizes: array of TPoint;
Papers: array of SHORT;
begin
with Printer do
begin
PrinterName := PChar(Printers[PrinterIndex]);
PaperCount := DeviceCapabilities(PrinterName, '',
DC_PAPERNAMES, @Buffer, nil);
SetLength(PaperNames, PaperCount);
SetLength(PaperSizes, PaperCount);
SetLength(Papers, PaperCount);
for i := 0 to PaperCount - 1 do
PaperNames[I] := PChar(@Buffer[I * 64]);
DeviceCapabilities(PrinterName, '',
DC_PAPERSIZE, @Buffer, nil);
PaperSizeArray := @Buffer;
for i := 0 to PaperCount - 1 do
PaperSizes[I] := PaperSizeArray^[I];
DeviceCapabilities(PrinterName, '', DC_PAPERS, @Buffer, nil);
for i := 0 to PaperCount - 1 do
Papers[I] := PWordArray(@Buffer)^[I];
end;
end;
