Bookifier

An easy way to print bind-ready booklets, in order to make (actually assemble) books right in your desktop.

The main goal is to be able to print books in a flexible and easy way. Currently, it supports:

Creating a ready-to-print pdf with as many sheets per booklet as you want.
Autofill with blank pages in order to use any number of pages as input.
Does not require a duplex printer at all (and lets you print with a non borderless printer too, such as some Canon models as mine)

bookifier --outfile output.pdf --infile input.pdf --start first_page --stop last_page --size sheets_per_booklet [--help]

To make this works, do this:

Fold all sheets by half (I highly recommend to use A4, since once folded it is A5)
Put the sheets one by one in the printer tray (you can put them all at the same time, just not one inside the other)
The explanation in case you didn't get it, goes now: Imagine you fold a single A4 sheet. You would get 4 printable pages, A-B on one side, C-D on the other. Now, the thing is this app will print A, then B, then C and D. So what you need to do is to print all A sides, then all B sides. After that fold inside out each sheet and print all C sides, and then all D sides. Remember to choose A5 as page size, and to scale properly, if necessary.

Some things that I would like to implement soon are:
