[cups.bugs] cupsGetOption("device-uri", dest->num_options, dest->options) returns null

[Michael Sweet]

CUPS 1.1.x did not expose the device-uri attribute in the options array.  You need to use  the IPP APIs to send a CUPS_GET_PRINTERS request and then parse the response (see the source for the "lpstat" command for inspiration)
