Hi,

I need to obtain the detailed information about a printer:

DriverName
PortName
DeviceName

These things don't seem to be available in the TPrinter object.

Thank you!

to get the printers names do this:

Create a new proyect
add a listbox
add a button
on the click event of the button write
   Listbox1.items.addstrings(printer.printers);
Run it!

Hi mikepj,

these

DriverName
PortName
DeviceName

can be found by printers.GetPrinter() !

Or you can use the GetPrinter() windows API. ALthough the Printers function getprinter is just an encapsulation of this windows api function...

example :

var
Device : array[0..255] of char;
Driver : array[0..255] of char;
Port   : array[0..255] of char;
hDMode : THandle;
PDMode : PDEVMODE;
begin
  Printer.PrinterIndex := Printer.PrinterIndex;
  Printer.GetPrinter(Device, Driver, Port, hDMode);

---> you got the info you needed : Device, Driver, Port
 
end;

Regards, Zif.

and windows api example :

different levels of info (see api help!)

printers.getprinter uses a different level if on win NT (level 4)or Win95/98 (level 5)

Var
   pInfo: PPrinterInfo2;
   bytesNeeded: DWORD;
   hPrinter: THandle;
           
Begin
  GetPrinter( hPrinter, 2, Nil, 0, @bytesNeeded );
  pInfo := AllocMem( bytesNeeded );
  try
   GetPrinter( hPrinter, 2, pInfo, bytesNeeded, @bytesNeeded );
   With pInfo^ Do Begin

   End;
  finally
   FreeMem( pInfo );
  end;
end;

Dear ZifNab,

Thank you for your answer; it works!  I had looked a lot at GetPrinter but decided that it didn't have what I needed after I saw that the first three parameters didn't have "var" before them.  Because they're PChar types they don't need to have "var" in front?

Thank you for your help!
