Vista - RE: PrintTicket difficulties

If you convert the error code to hex you get 0x80040154 and this seems to be
REGDB_E_CLASSNOTREG.
You don't specify the OS or version of WinFX that you are using, but my
guess is that you are using the November CTP of the Windows SDK on Windows XP
or Server 2003?

If I'm correct then your problem is almost certainly that the OS doesn't
have PrintTicket support yet, and that the error code is trying to tell you
that the driver you are using doesn't have a Print Ticket provider interface.

Basically for Print Ticket support to work with a driver then something has
to provider a PrintTicket provider COM interface for the WinFX classes to
use. For legacy drivers running on Vista driver-writers will have a choice of
how to do this. The driver-writer can either implement their own PT Provider
interface, or the OS will do it for you. (The new Unidriver for Vista will
include PT support in box). What I don't know yet is exactly how the
downlevel support for PrintTickets will work (or if that it will be made
available downlevel).

The error message that you are seeing suggests that the WinFX code cannot
find a PT Provider interface. This implies that the driver you are using does
not support the PT Provider interface and that the OS version you are using
does not support this for the driver.

Thanks for clearing that up Judy.

I am indeed running the Nov CTP on Windows XP Professional. My next
question is - how do I print from a WPF application on Windows XP? Since
WPF is available 'downstream' for XP, I had assumed the XPS printing
functionaility would be as well. Is this just a case of incomplete
functionality in the Nov CTP? I was able to get a rudimentary 'save to XPS'
routine working, so I would assume that is the case.

I found the printing examples at Feng Yuan's blog:
http://blogs.msdn.com/fyuan . It's quite obvious he's talking about Vista,
but he doesn't make any mention about the functionality being broken or
unavailable on XP.

At any rate, this is a CTP, so I can be patient if need be.

Thanks,

Fred
