history

Project history and usage

qprint is John Walker’s public-domain command-line encoder and decoder for MIME Quoted-Printable data. It is designed as a serial file filter and is commonly suited to automated mail-processing pipelines.

Project history

John Walker published qprint through Fourmilab as a public-domain command-line utility. The official page documents version 1.1, revised on 17 December 2014, and distributes source plus Unix build instructions and a Windows executable.

Adoption history

qprint is packaged across Homebrew, Debian, Ubuntu, Arch, Nix, MacPorts, and openSUSE according to source_facts.package-manager, giving the small standalone utility unusually broad Unix-like package-manager coverage.

How it is used

Run qprint in encode or decode mode with optional input and output files; a missing filename or “-” selects standard input or output, making the program pipeline-friendly.

The binary option preserves exact byte sequences, while the manual recommends Base64 instead when mostly binary input would make Quoted-Printable excessively large.

Why package nerds care

qprint represents the classic Unix-filter approach to an Internet mail encoding: a small public-domain executable, usable in pipelines, with no service, account, or dependency-heavy runtime. Its cross-distribution availability makes it useful when scripts need a named quoted-printable filter rather than a language-specific library.

Timeline

2014-12-17: qprint 1.1 documentation was revised and published by Fourmilab.

Related projects

The official manual points to base64 as the more economical MIME encoding for largely binary data.
Quoted-Printable is defined by the MIME standards; the qprint manual references RFC 1521 and its successors.
