Existing equipment
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

Existing printing solution
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
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
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
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
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
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
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
