Thermal Printer as D&D / TTRPG Utility

Documentation

Turn every thermal printer
into a TTRPG companion machine!

With Sales & Dungeons you can create highly customizable handouts, quick reference and much more for your Dungeons and Dragons (or other PnP) Sessions. Most Thermal Printer are small in
size and can be taken with you and kept right at the gaming table. Use-cases range from printing out magic items, spells or a letter that the group found to little character sheets of your
players to use as DM note. The possibilities are nearly endless!

Random Generator

More than just static data! You can also create random generators. You can generate random names, items, monsters or even full dungeons and encounters. Only your imagination is the
limit.

Session Grid

Organize your sessions with the session grid. You can create buttons to trigger random generators or quickly access templates. You can even share the grid via a link in the same
network, enabling your players to trigger prints themselves or use a different device like a mobile phone.

LLM Support

Use the power of LLMs to generate content. You can let the AI generate new entries for your Template or translate them into a different language. You can also run LLM prompts inside
of generators to get more organic results.

You can use
OpenAI,
OpenRouter
and even
local models giving you the flexibility to use the service and model you prefer.

Coming Soon:
Generate the whole template design (HTML, Nunjucks, etc.) based on prompts, so that even without any advanced HTML knowledge you can create your own templates.

Sales & Dungeons functions as a utility designed to transform thermal printers into companions for Tabletop Role-Playing Games, specifically Dungeons and Dragons or other Pathfinder systems. The core functionality revolves around creating highly customizable materials such as handouts, quick references, character sheets for players, and detailed notes for Dungeon Masters, allowing users to print essential game content directly at the table. This utility leverages the small size of thermal printers, making the content easily portable.

Technically, the software demonstrates broad compatibility, operating across major operating systems including Windows, OSX M1, OSX Intel, and various Linux architectures such as AMD64 and ARM, facilitating cross-platform use. Advanced features extend beyond simple printing to include sophisticated random generation capabilities. Users can create random generators for names, items, monsters, or entire dungeons and encounters, allowing for limitless creative scope. Session organization is managed through a session grid, which allows for the creation of buttons to trigger these random generators or access templates, with the added flexibility of sharing the grid via a network link so players can trigger prints from different devices.

The platform incorporates advanced artificial intelligence capabilities through support for Large Language Models (LLMs). LLMs can be employed to generate new content for templates, perform translations, or refine results generated by the random generators, offering organic and flexible content creation. This LLM integration supports the use of services like OpenAI, OpenRouter, and local models, providing users with flexibility in selecting their preferred service or model. Future plans include generating the entire template design based on prompts to lower the barrier to entry for creating custom templates.

Template creation is facilitated using HTML, which allows for complex styling with CSS. Data insertion into these templates can be handled using the Nunjucks templating engine or JavaScript. Data importation is highly flexible, enabling the system to ingest information from various sources including CSV, FoundryVTT Modules, Fight Club 5e XML Format, 5eTools Format, and JSON, ensuring compatibility with existing game data structures. Furthermore, the application features a workshop component where users can share their custom Templates, Generators, and Data Sources with the community.

Connectivity to thermal printers is supported through various methods, including Windows Direct Printing, Raw USB Printing, CUPS for Linux and Mac, and Serial communication protocols. The project is free and open source, licensed under the MIT License, with the source code available on GitHub. Privacy is prioritized, as the system does not collect personal information; data collection is limited to anonymous usage statistics gathered via Umami Analytics, which tracks page visits, visit duration, and device information without tracking individual users. The development of this application was initiated approximately five years prior to the current documentation.
