How to start a process with a printto verb AND printer name

[Shan McArthur]

Hello,

I am trying to start a process with the shell and invoke the "printto" verb
but am having difficulties providing the printer destination. I am trying
to print a file to a specific printer from within a .NET application.

I am using System.Diagnostics.Process and have set the
StartInfo.Verb="printto". I have tried unsuccessfully to set the printer
destination in the parameters, and adding it to the verb just throws an
exception. None of the .NET documentation deals with how to do this, and
even the legacy documentation provides no working examples.

The only approach I can think of is to read the registry for the
configuration information for the file's extension, then locate the printto
verb, parse out the command, and launch the process directly. This is
extremely ugly and does not deal with DDE or any other supported shell
extension.

Does anyone have any idea how to invoke the printto verb AND provide a
printer destination?

Thanks,
Shan McArthur

Hi,

You can specify the printer name in the ProcessStartInfo.Arguments. I
tested on my side and it works properly:

ProcessStartInfo psi = new ProcessStartInfo();
psi.FileName = "C:\\CLDMA.LOG";
psi.Verb = "printto";
psi.Arguments="\\\\ComputerName\\PrinterName";
psi.UseShellExecute = true;

Please refer to the following KB article for more information on print
switches:

//Note: Param2 will be stuffed into the %2 placeholder in the arguments
string, etc.
psi.Arguments = "Param2 Param3 Param4";

Hope this helps.
