The printing logic now uses the editing code. Thus layout and drawing are all the same logic, whether to the screen or to the printer. This will hopefully address a number of complaints about how shoddy the printouts have been.

New features include:
- Choice between printing out the vernacular or the back translation
- Progress indicator, including graying out underlying window
- Ability to explicitly edit the watermark

A few odds and ends remain, waiting on the styles rewrite; the main one being that currently the fonts are zoomed to the user's zoom setting, which should be a screen phenomena, not printer.
