Type of Print Driver: PCL or Postscript

After a print driver is installed on Windows XP/2000, is there a way to determine what type of driver it is – without sending data to the printer? We have many printers which can use either PCL or Postscript. Print queues have been set for each printer/driver type.

I’m trying to write VB code which will choose the correct print queue based on user selections. I need to know which driver type to set driver options for the output.

Is there a Registry Key, driver filename or something else which has this info? I tried looking at the DevMode structure but there’s no documentation for this.

We now have various HP, Xerox and Canon models.

Thanks for any help you can provide.
