You could check the contents of the driver -CDROM that came with your printer. Study the <filename>*.inf</filename> files lcoated on the CDROM. This -may not be possible, since the <filename>*.inf</filename> file might be missing. Unfortunately, vendors have now started -to use their own installation programs. These installations packages are often in some Windows platform -archive format. Additionally, the files may be re-named during the installation process. This makes it -extremely difficult to identify the driver files required. -</para> - -<para> -Then you only have the second option. Install the driver locally on a Windows client and -investigate which file names and paths it uses after they are installed. (You need to repeat -this procedure for every client platform you want to support. We show it here for the -<application>W32X86</application> platform only, a name used by Microsoft for all Windows NT/200x/XP -clients.) -</para> - -<para> -A good method to recognize the driver files is to print the test page from the driver's -<guilabel>Properties</guilabel> dialog (<guilabel>General</guilabel> tab). Then look at the list of -driver files named on the printout. You'll need to recognize what Windows (and Samba) are calling the -<guilabel>Driver File</guilabel>, <guilabel>Data File</guilabel>, <guilabel>Config File</guilabel>, -<guilabel>Help File</guilabel> and (optionally) the <guilabel>Dependent Driver Files</guilabel> -(this may vary slightly for Windows NT). You need to take a note of all file names for the next steps. -</para> - -<para> -Another method to quickly test the driver filenames and related paths is provided by the -<command>rpcclient</command> utility. Run it with <command>enumdrivers</command> or with the -<command>getdriver</command> subcommand, each at the <filename>3</filename> info level. In the following example, -<emphasis>TURBO_XP</emphasis> is the name of the Windows PC (in this case it was a Windows XP Professional -laptop). I installed the driver locally to TURBO_XP, from a Samba server called <constant>KDE-BITSHOP</constant>. -We could run an interactive <command>rpcclient</command> session; then we would get an -<command>rpcclient /></command> prompt and would type the subcommands at this prompt.

I do not either. However, only the last one, which -you arrived at with steps C.1 through 6 will permanently save any settings which will then become the defaults -for new users.

Windows 200x/XP allow per-user default settings and the ones the -administrator gives them, before they set up their own. The parents of the identically-looking dialogs have a slight difference in their window names; one is called <computeroutput>Default Print -Values for Printer Foo on Server Bar"</computeroutput> (which is the one you need) and the other is called -<quote><computeroutput>Print Settings for Printer Foo on Server Bar</computeroutput></quote>.
