Connaitre les Avantages & Désavantages Pilotes Imprimantes Isolés - Partagées - NonPartagées RRS feed

  • Question

  • Bonjour,

    Je pense avoir compris les différences lorsqu'on souhaites isoler ou non des pilotes d'impression notamment pour des serveurs RDS où  si une impression plante lié à un pilote  isolé cela ne plante pas les autres utilisateurs.

    Mais du coup, je suppose cela apporte un désavantage, non ? cela doit prendre plus de ressource étant donné que cela utilise un autre spool , non ?

  • Cela utilise plus de mémoire en résumé, mais tu va avoir moin de bug avec le spooler si tu a des erreur de driver; voir ce doc en exemple, il l'explique bien ! HP Universal Print Driver and Microsoft Driver Isolation Mode F.A.Q.s

    Le doc est pour HP, mais le principe reste le meme par contre

    What are the driver isolation mode settings for Windows 7 and
    Windows Server 2008 R2?
    • No Isolation—The driver runs in Spoolsv.exe (the same as for Server 2003, Windows Vista,
    Windows XP, and Server 2008 SP2). All drivers set to no isolation share Spoolsv.exe. The failure
    of one driver could cause the failure of the entire print system.
    • Shared—Drivers share the same PrintIsolationHost.exe, separate from Spoolsv.exe, but not
    separate from other drivers within the shared PrintIsolationHost.exe process. The failure of one
    driver could cause the failure of all drivers sharing the isolated process, but would not cause
    failure to Spoolsv.exe.
    • Isolation—Each driver runs in its own PrintIsolationHost.exe process, separate from Spoolsv.exe,
    and separate from other drivers in isolation. Failure of one driver would not impact other drivers.
    Each print queue does not operate in its own instance of the PrintIsolationHost.exe. Instead,
    multiple queues using a single driver utilize the same instance of isolationhost.exe.

    Is HP UPD performance impacted in driver isolation mode?
    Like other drivers on the system, the HP UPD competes for shared resources on the server. System
    resources are required for each driver(s) placed in isolation mode and the Windows system manages
    the resource. For each driver defined to run in full isolation mode, a unique instance of
    PrintIsolationHost.exe must launch, or drivers in shared isolation can share an instance of
    PrintIsolationHost.exe. Trade-offs exist between the stability achieved with driver isolation and
    demands on the print server or client. To optimize performance of the system, the Microsoft operating
    system opens and closes PrintIsolationHost.exe as required during print service operations.
