This release of AS/U fully supports Windows NT-style printing
protocols. A.*.* versions of AS/U only supported "down-level" print
protocols that limited support for NT clients. With support for
"up-level" printing, AS/U now allows centralized administration
of AS/U printers from a Windows NT 4.0 client. Administrators may
load all printer drivers for various operating systems (Windows
95, Windows NT 3.51, Windows NT 4.0) on the AS/U server which are
then downloaded to clients when required.
Note, however, that with uplevel printing enabled, Windows
NT 4.0 and Windows 95 clients will NOT be able to connect to a printer
UNTIL an administrator has loaded the correct print driver for that
printer.
Printers originally shared when AS/U did not have uplevel
printing enabled (or shared using previous versions of AS/U) do
not have any printer drivers associated with them; thus, administrators
must first upload printer drivers for each formerly "down-level"
printer before clients may access them as "up-level" printers.
For these reasons, there is an option to disable NT-style
printing during installation.
Installation Option to Disable NT-Style Printing |
 |
If migrating from a previous release of AS/U, the installation
routine will provide an option to disable uplevel printing support.
If uplevel printing is disabled, the following uplevel printing
features will not be available:
Administration of AS/U printers from
Windows NT 4.0 clients
Upload printer drivers from Windows NT 4.0 clients
Automatically down load printer drivers to clients
connecting to AS/U printers
With uplevel printing disabled, all clients will still be
able to use printers on the AS/U server, but they will appear as
downlevel printers.
NT-style printing can be enabled later by setting a registry
keyword.
Enabling/Disabling NT-Style Printing |
|
You may enable or disable uplevel printing functionality on
an AS/U server at any time by setting the AS/U registry entry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\AdvancedServer\Parameters\DisableUpLevelPrinting
Setting this registry key to 0 enables uplevel printing support;
setting it to 1 disables uplevel printing support. The AS/U server
must be restarted for the entry change to take effect.
Alternate Procedure to Add a Printer |
|
In addition to the procedure specified in the AS/U manuals,
you may also use the "Add Printer" wizard to add printers to an
AS/U server:
Select Start, Run..., type in \\asuserver, and then click OK
In the asuserver window, double click Printers,
and then double click Add Printer.
Follow steps specified in the wizard
If an existing HP-UX lp spooler destination (lpdest for
example) does not appear as an AS/U printer port, execute the following
on the AS/U server:
# net device lpdest
