How to print from Ubuntu using a Dell Printer...

Hello,

I just found the Ubuntu system and I have a Dell 720 printer, but I
can't seem to get it to work with Ubuntu.  I've tried using the
information I found on line, but I get all of these error messages and I
still can't print.  I tried to print a test page and I received the
following information to use with a bug report...


Page 1 (Choose printer):
{'cups_dest': <cups.Dest object at 0x949dd00>,
 'cups_instance': None,
 'cups_queue': 'Photo_Printer_720',
 'cups_queue_listed': True}
Page 2 (Check printer sanity):
{'cups_device_uri_scheme': u'usb',
 'cups_printer_dict': {'device-uri': u'usb://Dell%20/Photo%20Printer%
20720',
                       'printer-info': u'Dell  Photo Printer 720',
                       'printer-is-shared': True,
                       'printer-location': u'',
                       'printer-make-and-model': u'Generic text-only

                       'printer-state-message': u'',
                       'printer-state-reasons': [u'none'],

Page 3 (Printer state reasons):
