Steps to reproduce:

Went to calendar and highlighted event for printing and then went to print. On print screen I checked the event desired to print, as usual.

Actual results:

The items to print on the print screen are not there.....The screen is blank..

Expected results:

The event should have shown on the screen to be printed.

Printing is broken since Daily 75.0a1 and still broken in 75.0b2.

It is fixed in 75.0b3 which could be released in a couple days.

This is another issue. The actual printing works, but it is just (like the preview) blank.

Sorry, I did not understand that "print screen" meant print preview dialog and should have tested this before marking it as a duplicate.

So the steps to reproduce would be something like the following.

Select/highlight one or more event or task in the Calendar tab.
Select File > Print from the Menu bar, Print from the Menu button, or use the Ctrl+P key combination.
When the Print preview dialog opens select "Selected events/tasks".

In the error console I see this:

Can't print if there's no template to print from. I think we broke this when shifting around the calendar theme files. I've moved the templates out of skin and in to content as that's more appropriate anyway.
