Re: Regarding multiple devices installed



Support for multiple printers with the same model and manufacturer information is available in Panther for printers which use Apple's USB browser support. For other (vendor implemented) USB connections, it's up to the vendor to provide that support. This support was not available pre-10.3

We key off the 1284 Device ID string, not Vendor ID and Product ID so that printers that use USB-parallel dongles will also work. This feature works best if your printer has a unique serial number (USB device information), but we will use the USB location ID property as a fall-back to distinguish printers.

Yes Olav.
It is about binding multiple printers to print queues on OS 10.2 and later.
I have two printers with the same Vendor ID and Product ID and I need to
create queues for both of them when they are connected to my Mac box through
USB.


Any help will be appreciated.

Regards,
Samuel

Samuel,

Since you specifically mention printers, let me just say that an
"imaging driver" like a printer driver which interacts with
applications, the graphics system, IOKit, and users, has a printing
list that might be more appropriate for your question. See
http://lists.apple.com/mailman/listinfo/printing  End users are
encouraged to use the discussion forums on the Apple website.

There are differing levels of support for printer queues with multiple
printers of the same time depending on whether you're running OS
8/9/Classic or OS X 10.1 or 10.2 or 10.3. At a minimum, we'd need more
information to understand what you're trying to do before I could
answer your question as far as binding multiple printers to print
queues (if that indeed is what your question is about).

Hi,
I want to install two usb devices with the same vendor ID and
product ID and the same class (say printer class). How do I do this?
When I
tried to install two printers of the same make & model, the later
installation overwrites the previous installation. Is this the standard
behaviour?
