Thank you! Any paper/pen combination you would recommend?I might revise the project sometime later.

@@arkadiy4430 You can buy japanese bleed proof paper, you could get a nicer ballpoint pen that won't bleed with slow writing, something with a finer tip will have less ink surface area to bleed. There are a couple ways to do it. As long as the printer can press down enough to use a ballpoint pen I think it should be better. There are also ballpoint gel pens that might work better for this application as well.

I just avoided using them, the whole drivetrain for x any y axis are these chained worm gears and a fixed gear on the carriage. As you may know, the worm gears are slightly shorter than 2 studs, but after chaining them together I had an extra 1/2 stud space which I fit tightly with a half bush. As for the pen holder I had to use a gear chain so backlash was unavoidable. That is one of the reasons the pen bleeds into the paper as much as it does.

I had them, but I got stuck with how to make it go in directions that are very close to right angles. The motor that has to do the short move would just stall if it had to move very slowly. Maybe in the future I'll rebuild it but with a rotating base, this way it would be able to go in any angle.
