gtkunixprint Functions — the built-in functions of the gtkunixprint module
    def gtkunixprint.enumerate_printers(func, data=None, wait=True)| 
 | a function to call for each printer | 
| 
 | user data to pass to func | 
| 
 | if True, wait in a recursive
          mainloop until all printers are enumerated; otherwise return
          early | 
This function is available in PyGTK 2.10 and above.
Calls the function specified by func for
      all gtkunixprint.Printers.
      If func returns True, the
      enumeration is stopped.
The signature of func is:
  def func(printer, user_data):
      where printer is a gtkunixprint.Printer
      object and user_data is
      data. Note if data is
      not specified user_data will not be passed to
      func.
