cproudlock 389e620261 Initial commit: SNMP scanner and Zabbix template generator 
Tools for printer discovery and monitoring:
- snmp_scanner.py: SNMP-based printer discovery
- generate_printer_templates.py: Generate Zabbix templates
- analyze_supplies.py: Analyze printer supply levels
- extract_summary.py: Extract printer data summaries

Includes Zabbix templates for:
- HP Color/Mono printers
- HP DesignJet T1700
- Xerox Color/Mono/Enterprise printers
