Drivers for Microsoft systems contain multiple files. Often, multiple drivers

share one or more files. During the MS installation process files are checked

to insure that only a newer version of a shared file is installed over an

older version. There are several possibilities for this comparison. If there
|

is no previous version, the new one is newer (obviously). If either file is

missing the version info structure, compare the creation date (on Unix use

the modification date). Otherwise chose the numerically larger version number.

a. Call DrvPrintEvent with PRINTER_EVENT_INITIALIZE

b. Call DrvConvertDevMode with CDM_DRIVER_DEFAULT to get default DEVMODE

2. Call SetPrinterData with the 'magic' key and the DEVMODE as data.

The last step triggers saving the "driver initialization" information for

this printer into the tdb. Later, new printers that use this driver will

A printer and a printer driver are 2 different things.

NT manages them separatelly, Samba does the same.
|

Why ? Simply because it's easier and it makes sense !
|
|
|
|
Now explanation: You have 3 printers behind your samba server,
|
|
2 of them are the same make and model (laser A and B). But laser B
|
|
has an 3000 sheet feeder and laser A doesn't such an option.
|
|
Your third printer is an old dot-matrix model for the accounting :-).
|
|
|
|
If the /usr/local/samba/lib directory (default dir), you will have
|
|
5 files to describe all of this.
|
|
|
|
3 files for the printers (1 by printer):
|
|
NTprinter_laser A
|
|
NTprinter_laser B
|
|
NTprinter_accounting
|
|
2 files for the drivers (1 for the laser and 1 for the dot matrix)
|
|
NTdriver_printer model X
|
|
NTdriver_printer model Y
|
|
|
|
jfm: I should use this comment for the text file to explain
|
|
same thing for the forms BTW.
|
|
Je devrais mettre mes commentaires en francais, ca serait mieux :-)
