Depending on your browser, there are a couple adjustments that you may need to make.
1. Enable the option to include background images and colors.
2. If the Saturday column of the month view appears too narrow, then adjust the Scale setting to to a smaller percentage such as 70% or 90%. If it appears too wide, then increase the Scale until it is the correct width.
3. Adjust the margins to make the printable area wider.
4. If the calendar isn't displaying correctly further reduce the scale and/or adjust the margins.
Note: Chrome does not support adjusting Scale, so you'll need to use a different browser.
