Print dialog

[Sewi]

Our printing dialog is just a system-dialog for printer selection.

Some people use printed source very often, some meetings are better with printed source than with PCs and sometimes even "downloads" require a print function (​http://www.pgpi.org/pgpi/project/scanning/)

Here are some ideas, mostly from other IDEs/editors:

• Print file|selection|current sub|page a to b
• Print source|pod|both
• wrap at right page-border (I often print source landscape, don't think of 80 columns, A4 or letter, my father used to use A3 format)
• select print font and size and show how many pages would be printed
• auto-change font-size to fit the current number of pages (-1 if less than 25% of the last page are used), advoid a last-page-with-only three lines
• maybe get syntax coloring printed
• enable/disable line numbers
• put a light gray background behind each second line

Please close this ticket as soon as we have a new printing dialog and open a new one for all items which are not included in the first dialog version (or one ticket per open item).

It would also be nice to optionally support folding also for the printing functionality.
