Remarks

Some properties of the PrintQueue object represent characteristics of the print queue utility that runs on the computer, but others represent features or states of the printer itself. For example, NumberOfJobs is a characteristic of the print queue, but Location is a property of the printer. Many of the properties of the printer, such as whether it needs user attention, need to be passed, by means of the Refresh method, from the printer itself to the PrintQueue object. This should be done before the corresponding property (NeedUserIntervention) is read by your program. Similarly, when your program changes the values of one or more properties of a PrintQueue object, the change must be written to the actual print queue utility on the computer. Do this with the Commit method.

Caution

Classes within the System.Printing namespace are not supported for use within a Windows service or ASP.NET application or service. Attempting to use these classes from within one of these application types may produce unexpected problems, such as diminished service performance and run-time exceptions.

If you want to print from a Windows Forms application, see the System.Drawing.Printing namespace.
