2. Click View Devices & Printers.

3. Locate your printer in the list of printers.

4. Right click your printer and click Printing Preferences.

5. Change the Darkness setting to a number between 1 and 10. The lower the darkness number the darker the print.

6. Click Apply and then OK.

7. Print a tag and confirm that the print is darker now.
