What is the Spooler Subsystem App and Is It Safe?:
Almost all system processes, apps, and services on the Windows operating system have their executable (.exe) files. for example, SMSS.exe Powers the Microsoft Management Console, mmc.exe Powers the Microsoft Management Console, and so on.
Generally, Windows requires certain system services to perform the required functions on your PC. Others, Windows can do without. The Spooler Subsystem app is an important system process. In this explainer, we will walk you through the functions of the Spooler Subsystem app. Plus, we’ll show you what to do if the app ever crashes.
What is Spooler Subsystem App?
All Windows-powered computers ship with the Spooler Subsystem app. The program is an important system component responsible for “spooling” printing tasks. The app acts as an intermediary that transmits data from your application (browser, word processor, etc.) to your printer.
When you send multiple print jobs to your printer from the same or different applications, the Spooler Subsystem app stores the print data in a queue in your PC’s memory.
The spooler subsystem then feeds print jobs to your printer one at a time, in the exact order you sent them. That way, you don’t have to wait for your printer to execute a print job before sending another.
Basically, the Spooler Subsystem app facilitates handshaking between your printer and Windows computer.
