How do I print this document?

I'm normally pretty decent with computers, but I can't figure out how to do this.

Background: I created a Monopoly board using Presentations in my Google Drive (I don't have powerpoint or anything else to use). I can zoom in on the document to make it much bigger than I'll need it printed and it does not blur the image. I've exported it to pdf, jpeg and png.

Problem #1: When I export the picture to a different format, it loses all of it's clarity when I zoom in. I'm not sure how to keep it's original crispness. I think if I can solve this problem, my other problem would be solved, which is...

Problem #2: When I export the document to a printing service, the resolution is obviously to poor to print on a large paper. I'm trying to print on a 18x18 or 24x24 (or a rectangle which I could then trim to the appropriate size.).

Solutions?: Does anyone know how I could keep my original resolution when exporting? Alternatively, does anyone know of a place I could go (preferably a nation-wide store or one in Southeast Michigan) that allows you to print directly from a computer. I'm thinking if I can print directly from Google Drive without saving it, my resolution may be salvaged.

I would just try to redo this on a different computer (one with a photoshop or at least power point), but I worked really hard on this and, quite frankly, it looks pretty good =)
