//The way openstep handled NSPrinter was odd, it had a concept of "real"
//printers and
//not real printers. Printers that were not real were simply parsed PPDs,
//whether the printer was actually available or not was irrevelatn. This is
//is where the all the -types and +types methods come from. Apple's
//adoption of CUPS forced them to change this behavior, now, their types
//methods only search for the types of printers that are actually avaiable,
//it has nothing to do with the PPDs that happen to be avaiable on the file
//system. I think this is also the behavior we should adopt. Not simply
//because it is what Apple does but because it facilitates a generic printing
//backend system, especially one that will likely be using CUPS itself.
//This is why the following ivar is removed and the behavior of this class
//and the GSLPR Bundle has been changed. Doing this has also allowed me
//to put a lot of generic code in ths class that would have otherwise had
//to have been handles by each bundle. See +printerWithType: in NSPrinter.m
