Detailed Description

TheQPrinterInfo class gives access to information about existing printers.

Use the static functions to generate a list ofQPrinterInfo objects. EachQPrinterInfo object in the list represents a single printer and can be queried for name, supported paper sizes, and whether or not it is the default printer.
