Problem
You want to get information about print queues for printers on the current system.
Solution
To retrieve information about printers attached to the system, use the Win32_ PerfFormattedData_Spooler_PrintQueue WMI class:
PS >GetWmiObject Win32_PerfFormattedData_Spooler_PrintQueue | >> Select Name,TotalJobsPrinted >>
Name TotalJobsPrinted

To retrieve information about a specific printer, apply a filter based on its name, as shown in Example 244.

Discussion
The Win32_PerfFormattedData_Spooler_PrintQueue WMI class provides access to the various Windows performance counters associated with print queues. Because of this, you can also access them through the .NET Framework.
$printer = "Brother DCP1000" $pc = NewObject Diagnostics.PerformanceCounter "Print Queue","Jobs",$printer $pc.NextValue()
