How do I print Kotlin code with syntax highlighting?

Paste your Kotlin code into Codeprint and select Kotlin as the language. Keywords, types, and string templates are highlighted. Export via Print or PDF.

Does it support Kotlin coroutines?

Yes. Coroutine keywords including suspend, launch, async, withContext, and Flow are highlighted correctly.

Can I print Jetpack Compose code?

Yes. Compose annotations (@Composable), modifier chains, and state management code are all highlighted as standard Kotlin.

Does it highlight Kotlin DSL code?

Yes. Kotlin DSL patterns including type-safe builders, extension functions, and lambda receivers are all highlighted.

Turn Kotlin code into a PDF worth printing.

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

Kotlin Syntax Highlighting

Full support for Kotlin data classes, sealed classes, coroutines, extension functions, and scope functions.

PDF Export

Export Kotlin files as PDF for Android project documentation and code reviews.

Customizable Layout

Kotlin's concise syntax works well in multi-column layout. Adjust font for readability.

Line Numbers

Line numbers for referencing specific Kotlin functions and class members during reviews.

When you’d print Kotlin

Android Code Reviews

Print Kotlin Android code for offline reviews. Review ViewModels and repositories on paper.

Compose UI Reviews

Print Jetpack Compose code to review composable functions and state management patterns.

Teaching Kotlin

Create handouts for Kotlin courses. Kotlin's expressive yet concise syntax is ideal for print.

Backend Development

Print Ktor or Spring Boot Kotlin code for server-side architecture reviews.

How it works

Step 1

Paste Your Code

Paste your Kotlin 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 Kotlin?

Kotlin source is easier to review when its structure survives the move from editor to page. Full support for Kotlin data classes, sealed classes, coroutines, extension functions, and scope functions. 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. Line numbers for referencing specific Kotlin functions and class members during reviews.

Export Kotlin files as PDF for Android project documentation and code reviews. 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 android code reviews, compose ui reviews, and technical documentation. Your source stays in your browser throughout the process.
