Printing

Tachufind breaks some standard rules, the reason for breaking them is to sacrifice formality for speed, flexibility, and clarity. That means that it ignores margins that you would normally see in formalized word-editing programs. It also means, that if you want to print, you have two choices, open these rich text formatted files you have created in an editor and verify that you have enforced margin rules in it, and then print it out, or, take a screen shot from Tachufind and print it out that way.
Ignoring margins allows a lot of flexibility with regard to creating arrangements of data you would not be able to create in standardized, formalized applications. You can, as a result, create interlinears that stretch the width of your computer screen, import images that exceed what normal margins would have issues with, and this freedom is integral and intentionally introduced.
If you are dead-set on creating a document that will print in a standard editor, your best bet is to avoid using the enter key in Tachufind when the sentence gets close to the far right side and let it wrap around each time, that way your editor that you print in will set the margins on its own. Alternatively, if you only have a small amount of data, you could create your colored content in Tachufind and then copy it in to the program you plan on printing it out from.
