Does anyone know of any free printable bassoon fingering charts that are easy to read and for a beginner like me?

You can find tons of them online. Just google bassoon fingering chart and you can take your pick of several different kinds.

I have tried that, but being a beginner and all, I don't know which ones are good or reliable. (Although I CAN tell you good trombone, euphonium, baritone, tuba, etc ones...). Most of the ones I found were hard to read

I don't like to post websites here, but most charts will give you all you need to know for the first year or so of your bassoon playing experience. You just need to get one that is printable rather than asking you to press a key for the note before you get the fingering. There are no charts that I know of that will give you wrong fingerings; the basic fingerings will all be very similar. By the time you start to worry about alternate fingerings you will be so far along in your studies that you will know which chart you want or your teacher will have provided one.
