This test checks availability of the monochrome printing

on color printers.

To be able to run this test it is required to have a color

printer configured in your user environment.

Test's steps:
|
|
- Choose a printer.
|
|
- Press 'Print' button.
|
|
Visual inspection of the printed pages is needed.

A passing test will print two pages with

color and grayscale appearances
