"Print calendar to document" in Calendar List style causes double spaces between entries when printed in Notes 8.5.x Standard
You find that entries that are printed in your calendar are double spaced, and this restricts the amount of entries that will be able to print per page. You go to File - Print - Print Calendar to a document - Calendar List - From: Today To: End of the month, and find that the entries are double spaced in both the Print Preview and also when printing.
Resolving the problem
This issue has been reported to Quality Engineering under SPR MPGY89AKBG, and currently, there are no plans to address the issue in the 8.5.x codestream. As a workaround, you can use the option File - Print - Print Calendar - Calendar List - From: today's date To: End of the Month. The format of the entries printed will be a bit different, but not double spaced as before.
