<samba:parameter name="use client driver"
context="S"
type="boolean"
print="1"

<description>
<para>This parameter applies only to Windows NT/2000
clients. It has no effect on Windows 95/98/ME clients. When
serving a printer to Windows NT/2000 clients without first installing
a valid printer driver on the Samba host, the client will be required
to install a local printer driver. From this point on, the client
will treat the print as a local printer and not a network printer
connection. This is much the same behavior that will occur
when <command moreinfo="none">disable spoolss = yes</command>.
</para>
<para>The differentiating factor is that under normal
circumstances, the NT/2000 client will attempt to open the network
printer using MS-RPC. The problem is that because the client
considers the printer to be local, it will attempt to issue the
OpenPrinterEx() call requesting access rights associated with the
logged on user. If the user possesses local administator rights but
not root privilege on the Samba host (often the case), the
OpenPrinterEx() call will fail. The result is that the client will
now display an "Access Denied; Unable to connect" message
in the printer queue window (even though jobs may successfully be
printed). </para>
<para>If this parameter is enabled for a printer, then any attempt
to open the printer with the PRINTER_ACCESS_ADMINISTER right is mapped
to PRINTER_ACCESS_USE instead. Thus allowing the OpenPrinterEx()
call to succeed. <emphasis>This parameter MUST not be enabled
on a print share which has valid print driver installed on the Samba
server.</emphasis></para>
