Commented: Google Calendar
The Google Calendar app is convenient. You can log into the Google Calendar web through your internet-enabled printer's touch screen, at which point you can print day, week and month views of your Google calendar. I would like to see the ability to print the agendas of friends calendars, since these are typically significant (for example, my son's soccer schedule is viewable from my PC browser interface, but because it is an "other" calendar it does not appear in the agenda of the HP App Studio application). I expect a similar view/experience as what I have from my PC, so this was a limitation that should be fixed. Also, the < and > options to navigate are context sensitive, depending on whether you choose the day, week, or month form. You can navigate several months from today's date after selecting the month form, then navigate by day to a desired date in a future month more quickly. A "today" option should be added so that the calendar can revert back to the current date after navigating away by a significant number of days.
