ASN (Archive Serial Number) Cover Page Remover

The purpose of this script is to remove pages from a PDF document that contain QR Codes with data in the format of ASNXXXXXXX.

This script is meant to be used as a pre-consuption script for paperless-ngx

Why

There are some documents that I did not want to add a sticker to, but still keep physical copies. In order to automatically assign an ASN in paperless, I create ASN cover pages using asn-pdf-generator. However, I did not want this cover page to be a part of the digital document in paperless-ngx.

Setup

Run the following commands on the machine (virtual or otherwise) that is hosting paperless-ngx

1. Create a folder to save the scripts and virtual environment mkdir scripts
2. cd into scripts directory cd scripts
3. Create a virtual environment python -m venv venv
4. Activate the virtual environment using one of the commands below

source venv/bin/activate
. venv/bin/activate` #remember the dot!

5. Install the dependencies pip install PyPDF2 pyzbar Pillow
6. Copy remove-asn-cover-page.sh and remove-asn-cover-page.py to the scripts directory

Paperless Configuration

1. Set the PAPERLESS_PRE_CONSUME_SCRIPT to the full path of the bash script. This must be the full path including the script name. Example: /mnt/scripts/remove-asn-cover-page.sh
2. Set PAPERLESS_CONSUMER_ENABLE_BARCODES to true
3. Set PAPERLESS_CONSUMER_ENABLE_ASN_BARCODE to true
