Finding Installed Printers with the Script Task

APPLIES TO: yesSQL Server, including on Linux yesAzure SQL Database yesAzure SQL Data Warehouse noParallel Data Warehouse

The data that is transformed by Integration Services packages often has a printed report as its final destination. The System.Drawing.Printing namespace in the Microsoft .NET Framework provides classes for working with printers.


If you want to create a task that you can more easily reuse across multiple packages, consider using the code in this Script task sample as the starting point for a custom task. For more information, see Developing a Custom Task.


The following example locates printers installed on the server that support legal size paper (as used in the United States). The code to check supported paper sizes is encapsulated in a private function. To enable you to track the progress of the script as it checks the settings for each printer, the script uses the Log method to raise an informational message for printers with legal size paper, and to raise a warning for printers without legal size paper. These messages appear in the Output window of the Microsoft Visual Studio Tools for Applications (VSTA) IDE when you run the package in the designer.

To configure this Script Task example

  1. Create the variable named PrinterList with type Object.

  2. On the Script page of the Script Task Editor, add this variable to the ReadWriteVariables property.

  3. In the script project, add a reference to the System.Drawing namespace.

  4. In your code, use Imports statements to import the System.Collections and the System.Drawing.Printing namespaces.
