Our company recently upgraded from Outlook 2010 to Outlook 2013.  As a result, I now have an issue with printing my calendar.  When I select print preview for the calendar, the 30 minute minutes/appointments appear as 60 minutes.  However it is color highlighted on the left for the 30 minute period.  The same issue exists when the calendar is printed.  The calendar is displayed correctly except for print preview or printing.

I recommend that you post this in the Outlook Forum:  http://social.technet.microsoft.com/Forums/en-US/outlook/threads

Hi,

Please change the Print From and Print To settings in Outlook to have a try. In my testing, I set the timeframe to shorter than 11h, the issue resolved.

Based on my test, if the time duration is too long, the Time Scale would change to 60 minutes so the 30 minutes calendar items would be displayed imprecisely. Please try the following settings:
1. Go to File - Print - Print Options.
2. Click Daily Style in Print Style then click Page Setup.
4. On the Format tab, change the Print from and Print to time so it is shorter than 11 hours.
5. On the Paper tab, change the Orientation to Landscape.
6. Click Print Preview.

Regards,
