Printscan server

Version 2

This repository contains files used to set up our printscan server on a freshly installed Armbian. Confirmed to work with Buster.

Introduction

(see wiki for need and concept explanation)

Version 2 implementation works roughly as follows:

  • the Armbian-based device is connected to local network, and an all-in-one printer is connected to it via USB;
  • SANE and CUPS services are installed and running on the device;
  • CUPS is configured to provide a remote printer to network;
  • SANE is configured for local use only (default behaviour);
  • An headless X server is activable via noVNC;
  • This X session presents Simple Scan tool, allowing users to perform scans;
  • The resulted document is automatically uploaded to Kloud, in a temporary directory;
  • Every night, the directory from previous day is removed from Kloud.

Files

Installation

  • setup.sh is a script automating the installation and configuration of required software

Run

  • novnc.service, vnc.socket and vnc@.service manage the headless X session
  • scan.mount configures a tmpfs at boot where to store scanned documents before they're sent to Kloud
  • scan-to-cloud.{sh,service,path} trigger and manage the upload to Kloud
  • clean-cloud.{sh,service,timer} trigger and manage the removal of previous directory from Kloud
