If the grid lines do not show up when you print the calendar you may want to check the print settings for your browser.

Often the browser will be set up to not print the background color or images because they impair readability when converted to black and white or consume large amounts of toner or ink. In order to see the grid lines follow the instructions below to enable the printing of background colors and images.

In Microsoft Internet Explorer:
1. Select Tools and then Internet Options.
2. Click the Advanced tab.
3. Scroll down to the section labeled Printing and check the box labeled Print background colors and images.
