Exercises G26

Description:

The Document Printing Application is facing issue where it defaults to the "Laser Printer" option in the dropdown menu,
even when the laser printer is not available.
When the application cannot find the laser printer,
it attempts to switch to the "Dot Matrix Printer" (DMP) but repeatedly generates an error message during the printing process.

Steps:

1. Launch the Document printing application.
2. Navigate to "Print".
3. Observe the default selection in the "Printer" dropdown menu.
4. Click on "Print" button
5. When the laser printer is unavailable, the application should attempt to switch to the DMP.
6. Observe the error message generated during the printing process.

Expected Results:

-The application should select the appropriate printer (either Laser Printer or Dot Matrix Printer) based on availability and user selection.
-If the laser printer is unavailable, the application should automatically switch to the DMP without generating errors during printing.

Actual Results:

-The application consistently defaults to the Laser Printer option, even when the laser printer is not available.
-When attempting to use the DMP, the application generates an error message, preventing successful document printing.
