Hello,
I wanted to print the book and bind it, but the format is a little problematic if I wanted to print it as A5 book. Would it be possible to add a pdf that contains no double pages?
The short answer is: It is possible.
The long answer is: It's not something on the cards at this moment. It'd require Sam to shift from current projects, the major one being getting A Monster's Tail ready for physical print.
We do plan on getting it print friendly now that we have it up on Drivethru as well, to take advantage of their Print on Demand ability. We'll make an announcement when that's coming through the pipe.
