Overview

This example shows a quick way to provide the user a list of print available and set a default one.


Description
Printing a document from LabVIEW doesn't particularly offer many options, and it's notably hard to select one printer, or to even have a listing of the available printers. Some functions in windows provide a such listing, and enable a user to select a default printer.

The attached VI searches for all the available printers, and outputs a listing of those letters. The index command allows the user to select which printer has to be the default one (index =0 => default printer = first one to be listed).


Requirements

  • LabVIEW 2012 (or compatible)


Steps to Implement or Execute Code

  • Select the printer number as the default one.
  • Run the program

Hey Eric,

Thaks for digging through the classes to return the info.  Great for someone to use in their own code.  One piece of feedback that most code will include is to keep the current settings (ie read back the current printer and set that as the default printer again or some variation there in).  Currently, the only way to not change your current settings would be to pass an index outside of the range of printer indicies.  Just some food for thought.

I agree with Barney, I set the index default to -1 and got rid of the annoying out of range dialog

The In Range & Coerce needs to include the upper limit else you can't set to the last printer.
