PrintAudit

PrintAudit is a modern Python rewrite of the historical PrintAnalyzer Perl utility. It ingests CUPS page_log files, produces comprehensive usage, cost, and behavior reports, and supports modular outputs (CLI, CSV, HTML, email).

Features

• Comprehensive Analysis: Queue usage, user activity, temporal patterns, cost allocation, and more
• Cost Tracking: Currency-agnostic cost calculation with configurable rates per printer, department, or label
• Flexible Outputs: Multiple output formats (CLI, CSV, HTML, email) with plugin architecture
• Date Filtering: Analyze specific time ranges with --start-date and --end-date
• Work Hours Detection: Identify printing activity within configured business hours
• Modular Design: Easy to extend with custom output modules

Installation

From PyPI

pip install printaudit

From Source

git clone https://github.com/vhsantos/PrintAudit.git
cd printaudit
python3 -m venv .venv
source .venv/bin/activate
pip install -e .

Quick Test

PYTHONPATH=src python3 -m printaudit --config printaudit.conf.sample --dry-run

Configuration

Configuration File Search Order

PrintAudit searches for configuration files in this order:

1. --config /path/to/printaudit.conf (command-line override)
2. $PRINTAUDIT_CONFIG (environment variable)
3. /etc/printaudit/printaudit.conf
4. /etc/printaudit.conf
5. ./printaudit.conf (current directory)

Basic Setup

1. Copy the sample configuration:

   sudo cp printaudit.conf.sample /etc/printaudit.conf
   

2. Edit /etc/printaudit.conf and adjust:

   • page_log_path: Path to your CUPS page_log file
   • work_start / work_end: Business hours (7-22 = 7 AM to 10 PM)
   • outputs: Comma-separated list of output modules
   • enabled_sections: Which analysis sections to include

See Creating Output Modules for extending with custom formats.

Analysis Modules

PrintAudit provides comprehensive analysis across multiple dimensions:

• Queue Analysis: Usage by printer/queue with percentages
• User Analysis: Per-user statistics with pages per request
• Temporal Analysis: Hourly and daily usage patterns
• Job Analysis: Distribution of job sizes and copy counts
• Cost Analysis: Department/label-based cost allocation
• Media Analysis: Paper/media type usage
• Client Analysis: Source hostname tracking
• Document Types: File extension analysis
• Duplex Analysis: Two-sided vs. one-sided printing

See Analysis Modules Documentation for detailed explanations and expected outputs.
