Construction of an improvedPrinting System Diploma Thesis Ing. Martin Vogler
Existing Equipment • 35 PC-Rooms with printing facilities • 60000 users in current system • Each printing facility consists of: • Terminal model Digital VT420 • Printer model HP LaserJet 4xxx N • Terminalserverbox model Lantronix ETS4P • Cardreader device model TST CopyBox Diploma Thesis Ing. Martin Vogler
Existing Printing Solution • Limitations of the existing solution: • Very strict user and operating system environment • Very strict hardware pool • Modification of the standard hardware necessary • Expansive and inefficient maintenance Diploma Thesis Ing. Martin Vogler
Guideline for New Equipment • Using of existing network and user administration infrastructure • Using of existing hardware is preferable • Standalone PC should serve as the new printing interface Diploma Thesis Ing. Martin Vogler
New Printing Solution • Based on software • No modification of the printer model necessary • Current operating system: Windows XP • Migration to other operating systems easily possible • Program development with C# Diploma Thesis Ing. Martin Vogler
Programflow 1 • Start of printing • Click on desktop icon • Read needed parameters from INI - file • Build connection „printserver to printclient“ • Query all user files in spool directory • Printing a form on the desktop Diploma Thesis Ing. Martin Vogler
Programflow 2 • Selection of printfile by user • Read printfile and calculate number of pages in file • Build connection „printclientPC to printer“ • Get number of total printed pages from printer • Send printfilestream to printer • Get number of printed pages • Generate signal for CopyBox • At the end of printing close all connections Diploma Thesis Ing. Martin Vogler
Programflow 3 • Error management • Error recovery sequence closes all connection • Close program in a defined procedure • Error message on desktop Diploma Thesis Ing. Martin Vogler
Improvements of the new solution • Wide pool of printers • Reduces significantly the costs for a new printing facility • Reduces significantly the overall effort for maintenance • No a priori preferences for a specific printer model Diploma Thesis Ing. Martin Vogler
Acknowledgements • To the Staff of the FH for teaching • To my colleagues at work for ideas • For your attention Diploma Thesis Ing. Martin Vogler
