Some people get uneven extrusions with paper spools, since they can have higher friction against the spool holder compared to plastic spools. Usually only an issue with weak ungeared extruders, i.e. where the hobbed gear is attached directly to the motor's shaft. But if you get this problem then you can try wrapping the spool holder with teflon tape, or printing a mod that puts a ball bearing in the spool holder.
You can update your roller with a spinning one to fix any issue.
Yep, and that was like... the second thing I did for my printer. Since then I've gone to printing out of a warming box, but I still use the roller occasionally and I'm still glad I did it, it solved problems.
