## Detailed Description

A Printer object represents a printer.

You only need to deal directly with printers if you use the non-portable PrintUnixDialog API.

A Printer object allows to get status information about the printer, such as its description, its location, the number of queued jobs, etc. Most importantly, a Printer object can be used to create a PrintJob object, which lets you print to the printer.

Since gtkmm 2.10:

## Constructor & Destructor Documentation
