The genuine printisolationhost.exe file is a software component of Microsoft Windows Operating System by Microsoft Corporation. "PrintIsolationHost.exe" should reside in "C:\Windows\System32." Multiple instances may run at the same time depending on how many printer drivers are being used. It is a DCOM Server type of process, which has to be started by "DCOMLAUNCH", the DCOM Server Process Launcher. It allows Windows to implement "shared" or "isolated" mode Print Driver Isolation (PDI) for individual printer drivers that are PDI-compatible - some are not. PDI prevents an unhandled printer driver exception from also crashing the print spooler by loading some of the print driver's DLL's into PrintIsolationHost.exe's address space, creating a "sandbox". In "isolation" mode, one "PrintIsolationHost.exe" instance loads one driver, maximizing crash protection. In "shared" mode, an instance hosts multiple drivers; one driver's failure can only bring down the other drivers which that instance has loaded. While the "DCOMLAUNCH" service is always running in the background, this process only runs when required.
PrintIsolationHost stands for Printer Driver IsolationHost

Part of MS Windows operating systems. Runs after initial boot to isolate print drivers in case of crashes. You will see one copy of PrintIsolationHost.exe for each print driver you have in memory. The process(es) should terminate after they run. BB (further information)
On my Win7, the file is 18,944 bytes. Is it a problem? Kumara
Whenever it appears in my Task Manager, my printer won't work; it gives an error message. L. Hodges
Überflüssig wie ein Kropf! Schon der Name besagt doch, daß dieses Programm den Datenstrom vom Drucker isoliert, so daß zum Druck bestimmte Dateien für unbestimmte Zeit in die Druckwarteschlange geschoben und nie ausgeführt werden. Im Task Manager kann ich es nicht mehr loswerden, und mit jedem Windows-Neustart vermehrt es sich um ein Exemplar. Überaus lästig! a.e.corvis
Mit dem AnvirTaskmanager kann man dieses lästige Proggie von MS, das wieder mal etwas verschlimmbessert statt zu optimieren, ganz einfach blocken, man muß es nicht ertragen bloß weil der umstrittene Bill Gates es so will. Chris Montez
