winprint

A crate for printing to a Windows printer device using Windows API.

About Safety

This crate interfaces with several Windows API functions, necessitating the use of unsafe code blocks. Nevertheless, this crate is designed to be safe and sound to use. If you find any case that will break safety or soundness, please report it as a bug.

Development

Testing on Windows

Virtual devices are automatically created and used for testing, so simple cargo test will be okey.

For efficiency, cargo hack and cargo nextest may be used. The recommended command is:

cargo hack nextest run --all-targets --each-feature --skip default,test-utils --no-fail-fast

Some fixtures are required for tests, and they are shipped in the repo. If you want to learn how they are generated, see utils/gen-visual-regression-data/ and utils/gen-color-management-data/.

Testing on Linux Host

Since this crate is designed for Windows, it cannot be directly tested on a Linux host. However, a script is provided to run the test suite inside a Windows 11 VM on a Linux host.

See utils/test-in-windows-vm/README.md for details.
