What are the parameters for "printto" using shellexecute?

Question

I'm using Delphi's winapi ShellExecute to try to print to a user selected printer and not the default printer. I'm trying to figure out the syntax for a command using the printto verb.

What would an example shell execute statement look like if I wanted to print manual.pdf to a HP Laser Jet 4 with IP address 192.168.1.49?

(this is just an example, but if you can help me out, I can take it from there)

Answer 1

You need to pass the network network address of the printer in the arguments parameter.

ShellExecute(
  WindowHandle,
  'printto',
  PChar(DocumentName),
  PChar(PrinterNetworkAddress),
  nil,
  SW_HIDE
);
