I keep a couple of practical reference files in my dotfiles repo: shortcuts.md with keybindings I use most, and flows.md with step-by-step workflows. I wanted to print them so I could have them on paper while building muscle memory.
Turns out, printing Markdown cleanly is harder than it should be. Everything I tried either broke the formatting or required some clunky third-party service. So I built Markdown to Paper. It's a browser-first tool that lets you paste your Markdown, preview it, and cleanly print it out (or save as PDF) using your browser's native print dialog. No servers, no uploads, just clean printed Markdown.
