4075 Previously the code had a memory allocation problem because it always
4076 used the TALLOC_CTX from the Printer_entry*. This context lasts
4077 as a long as the original handle is open. So if the client made a lot
4078 of getprinter[data]() calls, the memory usage would climb. Now we use
4079 a short lived TALLOC_CTX for printer_info_2 objects returned. We
4080 still use the Printer_entry->ctx for maintaining the cache copy though
4081 since that object must live as long as the handle by definition.

5047 A printer and a printer driver are 2 different things.
5048 NT manages them separatelly, Samba does the same.
5049 Why ? Simply because it's easier and it makes sense !
5051 Now explanation: You have 3 printers behind your samba server,
5052 2 of them are the same make and model (laser A and B). But laser B
5053 has an 3000 sheet feeder and laser A doesn't such an option.
5054 Your third printer is an old dot-matrix model for the accounting :-).
5056 If the /usr/local/samba/lib directory (default dir), you will have
5057 5 files to describe all of this.
5059 3 files for the printers (1 by printer):
5060 NTprinter_laser A
5061 NTprinter_laser B
5062 NTprinter_accounting
5063 2 files for the drivers (1 for the laser and 1 for the dot matrix)
5064 NTdriver_printer model X
5065 NTdriver_printer model Y
5067 jfm: I should use this comment for the text file to explain
5068 same thing for the forms BTW.
