  1. CERN Print Manager Michel Jouvin LAL / IN2P3 jouvin@lal.in2p3.fr

  2. Printing Client Problem • Automatic client configuration • No privilege should be needed • Update capabilities • Roaming : Access to local printers for visitors • Should not require desktop configuration change (ex: domain membership) • Ex : LAL people at CERN CERN Print Manager - HEPix - Vancouver 2003

  3. SMB Printing • Windows native protocol for network printing • + : network served printers available to all users without client configuration • - : must be member of the same domain as the server • - : printer server must be Windows • SMB/LPR gateway (samba) : yet another layer to manage/troubleshoot CERN Print Manager - HEPix - Vancouver 2003

  4. Windows LPR Printing • + : LPD is the access protocol of printing services at LAL • No gateway involved • - : no central configuration possible • Configuration is more than a file (drivers…) • Mainly manual configuration • - : require administrator privileges to add a printer CERN Print Manager - HEPix - Vancouver 2003

  5. CERN Print Manager Approach • 1 central database describing all printers • Printer server (in a dedicated DNS zone) • Driver to be used for each printer • Per OS version (currently W95, WNT, W2K) • Printer default settings • 1 client with 3 main components • PrntTray : Printing Control Center (main application) • LPRServ : LPR client (ability to show LPR transactions) • PrinterWizard : add/remove printers, change defaults CERN Print Manager - HEPix - Vancouver 2003

  6. Printer Database Management • Reference database is an MS Access db • Text file database used by client (no MS Access required on client) • Database management tool : PrintMgr (GUI) • Add drivers to database • Driver versioning support • Add/remove printers • Generate text file database CERN Print Manager - HEPix - Vancouver 2003

  7. Client : General Characteristics • No privileges required • Impersonation to a dedicated privileged account when needed • Automatic update capabilities for binaries, configuration files and printer/driver configuration • Handled by PrntTray et PrinterWizzard • Through direct access (domain membership) or FTP • One control center to start all other stools • PrntTray • Deployment through MSI CERN Print Manager - HEPix - Vancouver 2003

  8. Client : PrntTray • Main task • Available as an icon in icon tray of main menu bar • Update binaries and configuration on startup • Can be disabled • Control LPR client (LPRSERV) • Launch PrinterWizzard and other tools CERN Print Manager - HEPix - Vancouver 2003

  9. Client : PrntTray GUI CERN Print Manager - HEPix - Vancouver 2003

  10. Client : LPRSERV • Use C:\LPRSERV as the spool directory • Show LPR Client from PrntTray allow to show LPR Client transactions • Can be configured for different types of LPD server • Lines present in control file CERN Print Manager - HEPix - Vancouver 2003

  11. Client : Printer Wizard • GUI to add/remove printer to local computer • Maintains and updates a local copy of the central database • Modify printer defaults settings • Test printers CERN Print Manager - HEPix - Vancouver 2003

  12. Client : Printer Wizard CERN Print Manager - HEPix - Vancouver 2003

  13. Multi-sites Configuration • Allow to switch between different sets of parameters • Central database locations, LPR parameters, … • No conflict between sites • Differents directories for data files • Differents registry paths • Site definition in an INI file • Client can be distributed with several sites preconfigured • Easy addition of a new site CERN Print Manager - HEPix - Vancouver 2003
