How do I print JavaScript code with colors?

Paste your JavaScript code into Codeprint and syntax highlighting is applied automatically. Keywords, strings, numbers, and comments are colorized. Click Print or PDF to export the formatted output.

Does it support JSX and React code?

Yes. Codeprint highlights JSX syntax within JavaScript files. For TypeScript React files (.tsx), select TypeScript as the language for the best highlighting.

Can I print Node.js server code?

Absolutely. Browser-side JavaScript, Node.js, Deno, and Bun code is highlighted correctly. CommonJS require() and ES module import syntax are both supported.

How do I handle long lines in JavaScript?

Long lines wrap automatically in the preview. You can also switch to landscape orientation or reduce the font size in settings for code with long lines like JSX templates.

Is my JavaScript code sent to a server?

No. All processing happens in your browser. Your code never leaves your device. Codeprint works entirely client-side with no server uploads.

Turn JavaScript code into a PDF worth printing.

Keep JavaScript syntax colors, line numbers, and the layout you choose. Preview every page and export the PDF without uploading your code.

JavaScript Syntax Highlighting

Full support for ES6+ features including arrow functions, template literals, destructuring, async/await, and optional chaining.

PDF Export

Download JavaScript files as professionally formatted PDF documents with syntax colors, line numbers, and clean typography.

Customizable Layout

Adjust font size, page orientation, and columns. Use landscape mode for long lines common in React JSX code.

Line Numbers

Toggle line numbers for easy reference during code reviews and debugging sessions.

When you’d print JavaScript

Code Reviews

Print JavaScript modules for offline review. Annotate printed code with comments about architecture, naming, and potential bugs.

Teaching & Tutorials

Create handouts for JavaScript bootcamps and workshops. Printed code with line numbers helps students follow along during live coding sessions.

Documentation

Include formatted JavaScript examples in API documentation, style guides, or technical specifications.

Debugging

Print complex JavaScript logic for whiteboard debugging. Trace execution flow on paper to find issues that are hard to spot on screen.

How it works

Step 1

Paste Your Code

Paste your JavaScript code into the editor or type directly. The language is auto-detected from the file extension.

Step 2

Customize Settings

Adjust font size, line numbers, columns, page orientation, and page size to match your needs.

Step 3

Print or Export PDF

Click Print to send to your printer, or PDF to download a formatted document with syntax highlighting preserved.

Why print JavaScript?

JavaScript source is easier to review when its structure survives the move from editor to page. Full support for ES6+ features including arrow functions, template literals, destructuring, async/await, and optional chaining. Codeprint keeps indentation and line breaks intact, then applies a restrained syntax palette so keywords, strings, comments, and identifiers remain distinguishable in print.

A paper review creates a different reading rhythm from an IDE. You can see more of the file at once, mark a questionable branch, compare related expressions, and refer back to a precise line without opening the same toolchain. Toggle line numbers for easy reference during code reviews and debugging sessions.

Download JavaScript files as professionally formatted PDF documents with syntax colors, line numbers, and clean typography. Page size, orientation, columns, and type size remain under your control, which matters when the source contains long expressions or dense blocks. It is a practical fit for code reviews, teaching & tutorials, and technical documentation. Your source stays in your browser throughout the process.
