Virtual Paperless-ngx printer on Raspberry Pi

What is this?

These are instructions to create a virtual "printer" for Paperless-ngx that runs on Raspberry Pi (I use Raspberry Pi Zero W). This way, you can "print" documents from your computer or phone, and they'll be submitted to your Paperless-ngx instance.

Instructions

Create a dedicated user in your Paperless-ngx instance on the Users & Groups page. It doesn't need too many permissions. image

Just stop using anonymous classes already
require 'benchmark/ips'
class A; end
foo = Class.new
Benchmark.ips do |t|
t.report("normal") { A.name }
t.report("anonymous") { foo.name }
