How do I print a weekly calendar with larger times and dates, as one can with the event type sizes ?

When printing a weekly calendar one can select a larger font for the Events in a calendar, but the dates and times still print in a wee, barely legible font. The horizontal and vertical lines on the weekly calendar are also very faint for us older viewers. Settings, Accessibility options do not address printing issues.

Can the printing font sizes be increased by the user, or is this something only a application development improvement can solve ?
