  1. Network printing in heterogenous environments Christoph Beyer christoph.beyer@desy.de Deutsches Elektronen Synchrotron IT Notkestr. 85 22607 Hamburg, Germany

  2. Printing @ DESY • ~300 printer and ~400 queues • 2 SUN E250 running SOLARIS 2.7 with 1GB memory each as server • ~250.000 jobs per month • No MAC and Novell support defacto • 2 administrators • LPRng 3.6.26 (slidely patched), IFHP 3.4.4, SAMBA 2.2

  3. Printing architecture @ DESY UNIX clients MICROSOFT clients - SOLARIS - LINUX - HP-UX - AIX - IRIX - NT 4.0 - 2000 - 95 / 98 SMB LPR - SOLARIS 5.7 - LPRng 3.6.26 - IFHP 3.4.4 - SAMBA 2.2 SPOOLA SPOOLB TCP / LPR

  4. The server • Take advantage of the flexibility of UNIX as a backend for queuing jobs and talking to the printer. Use software to present the UNIX queues to the clients using their native protocols • @ DESY: OS: SOLARIS 5.7 Printspooler: LPRng 3.6.26 Filter: IFHP 3.4.4 Tools: SAMBA 2.2 • Identical architecture, every printerqueues is served by either one machine or the other, every printer is known on both machines (failover)

  5. UNIX clients • Running LPRng • Automatic update via cronjob, and client printcap in afs • BSD and SysV binaries on all machines • Nice LPRng features like failover, debugging

  6. WINDOWS clients • Driver installation via the ‘add new printer’ wizzard • Download of printer configuration at printtime from the server via RPC • Internal job query and removal features of WINDOWS work • No need for any installation on the client !

  7. SAMBA 2.2 • First release that supports the native Windows NT printing mechanismus implemented via MS-RPC, previous versions only supported LanMan printing calls • Support for downloading printer driver files to Windows 95/98/NT/200 clients upon demand • Uploading of printer drivers via the Windows NT ‘Add Printer Wizzard’ (APW) or the Imprints toolset • Support for NT Access Control Lists (ACL) on printer objects • Fully equivalent behaviour to a NT printspooler in all points (driver installation, printing procedure, queue query)

  8. Windows printing using SAMBA 2.2 - printer installation via NT ‘add new printer wizzard’ - downloading printer driver file upon demand (at print-time) - printjob transfer via SMB - printer queue lookup with the WINDOWS internal GUIS - uploading of printer drivers via the NT ‘add printer wizzard’ - preconfiguration of printer drivers client admin - NT 4.0 - 2000 - 95 / 98 - NT 4.0 - 2000 - 95 / 98 SMB SMB spoola/b

  10. Summary • SAMBA and LPRng together can fully support both, UNIX and WINDOWS clients using their native protocols to present queues, handle delete requests etc. • The SAMBA installation at DESY is a test environment right now and will go into production within the next few weeks • During the tests we did not see any problems presenting ~400 queues to the WINDOWS clients • Performance is OK • In case of hardware problems a third machine, running SAMBA can join the NT domaine and provide printing service using the netbios name of the broken server
