snippetd

Snippetd is a micro-service that takes POST requests and schedules them to be printed on an ESC/POS-compatible ("receipt") thermal printer.

Current version: 0.9.0

WARNING

Version 0.9.0 has templates for 34 char printing, that is the "high dot density" that can be enabled on some (better?) printers. It also adds support for and uses the cutter. If your printer is 32 chars only better use the previous version (0.8.0).

Main things it does:

• Wraps each snippet in a nice header and footer (can be turned off per req.)
• Does basic length sanity checks, and has text and image modes
• Queues messages for printing, in case you really want to kill your printer
• Can also archive snippets with requests metadata
• And with archive now can also reprint (by checksum)
• Has expvared basic statistics
• In general tries to do the least and be reliable

What it doesn't do:

• Cares about security in any manner; Feel free to add a key/TLS/etc.
• It's not and will never be an "enterprise solution"

Showcase

None for now, given nobody will use this anyway :P

But this is a part of a larger project, with the second element being the soup2escpos. Been using this tandem for less than a month but so far I'm getting what I wanted, duh.
