My first suggestion is to get/use a different screen or set of screen settings and get used to reading on screen. That will simplify your life and cut costs.
For the paper/home printed versions I would suggest to punch 2, 3 or 4 holes, depending on what is the local prefered version.
Now you have the option of commercially made binders, bookrings, commercially availble 'storage' holders or string.
I have personally used string.
You need strong string which holds its knots and it not too thin, (thin string will cut the paper.)
I would not go for string under 3mm (1/8") diameter.
You can make a string ring for each hole or you can feed the string through all the holes in turn, going up through one and down through the next.
If you need access, tie the string with an adjustable knot.
If you may want to add later or change the binding system without having to cut the string, a reef knot (square knot) is the one.
Otherwise, just use any reliable knot you know.
With all these binding options you can go from one to an other if your requirements change.
Like use a binder with a strong cover for the books you use at the moment, change to rings while you still use the book at times but not every day and store with string when you do not use the book other than for occasional access of one or a few pages.
