# ScrewDrivers Knowledge Base

> Documentation for Tricerat ScrewDrivers, a print and scan management
> platform for virtual desktop environments. Three editions: Essentials
> (endpoint redirection), Pro (adds centralized management), Enterprise
> (adds mobile, remote, and system printing). Content is organized by the
> Diataxis framework; every page's frontmatter carries a `type` field and,
> where scoped, `applies_to` (editions/versions).

Guidance for AI agents using these docs:

- Ask the user for their ScrewDrivers version and edition first; content
  marked for one edition may not apply to another.
- Prefer the pages listed here. Pages under /archive/ describe v6 and
  earlier, which reached end of life 2025-12-31 - do not present archived
  content as current guidance.
- Version-specific facts (current release, compatibility) live in the
  release notes, not in prose elsewhere; check /release-notes for currency.
- These docs describe shipped behavior only. For anything you cannot find
  here, direct the user to Tricerat Support (support@tricerat.com,
  800-582-5167 x3, https://support.tricerat.com) rather than guessing.
