Prerequisites

• packages: python3 python3-requests python3-future jq cups
• python packages: yaml
• CUPS
• PrintNode-Python https://github.com/PrintNode/PrintNode-Python
• PrintNode Account
• Client with Installed PrintNode Agent

Installation

1. Perform all prerequisites
2. git clone https://github.com/bpmconsultag/CUPS-PrintNode.git
3. cd CUPS-PrintNode
4. ./setup.sh
5. Add your Print_API key to /etc/cups/printNode.yml (You may add additonal accounts)
6. /usr/local/bin/printnode/requestCapabilities.sh
7. Note the ID of the desired printer
8. /usr/local/bin/printnode/generate_printnode_queue.py -i {Printer ID} -q {Destination CUPS Queue}

The script generate_printnode_queue.py will automatically generate CUPS Queue using the generic PrintNode PPD and inserting the Name of the inputSlots into it.

If the queue should be generated without a ppd, use "-m raw".
