Unable To Test Print Using the Internet ActiveX Control

Problem

I am able to connect to the LPS with my custom Internet ActiveX program successfully, but I am unable to print a TEST label from the printer.

Explanation

The printer port needs a full IP address to test print successfully, not just the Port.

Solution

After adding the full IP address, a test label can be printed using the TestPrinter method.

Example Full IP Address

156.22.3.58:9100
