Data Access and Custom Reports

The default PaperCut MF installation stores data in an internal database. For the interested person, the database is Apache Derby - an open source database written by IBM and based on their DB2 Cloudscape Database. The internal database is optimized for embedded use, is very robust, ACID compliant and scales well. The internal database however is not designed for multi-application access. To access the data from an exteral source such as a reporting program, you'll need to consider running PaperCut MF on an external database (RDMS) designed for multi-user and multi-applicaiton user access. Common database solutions include Microsoft SQL Server, Oracle, and Postgresql. For more information see Chapter 20, Deployment on an External Database (RDBMS).

The PaperCut MF data structure is relatively simple and people with Crystal Report or SQL experience should have no problems extracting data or written custom reports. Report developers should keep in mind:

A database schema diagram can be found in the PaperCut MF knowledge base located at Database Schema Diagrams.

Plain Text Print Log

In addition to storing print log information in the database, a real-time, plain text log is also written into the directory:

            [app-path]/server/logs/print-logs
            

The log file is in a tab delimited format and a new log is created for each day. Files are named with the format printlog_yyyy_mm_dd.log and files are archived for 30-days. The tab delimited file can easily be imported into programs such as Microsoft Excel, Microsoft Access or other database.
