9X Printer Driver

NTDEV
1

Hi,

I am using a UNIDRIVER based Windows 9X Printer driver and set
the data type as EMF. When I print from Power point application(
Windows 98) it always print to Raw data type, but for other
applications, it creats temporary emf files properly and I could
process the emf files in the print processor.

I know a driver can control the data type. But I don’t
understand how an application like power point can force the
data type to raw when the driver supports EMF.

Can anyone explain me how is this happening and how to fix this?

Thanks,
Sridhar

Your default datatype selection in the printer properties doesn’t

guarantee anything. There are numerous factors that control whether EMF

or RAW gets spooled. Here are some of the factors:

Firstly, if the app uses the print apis directly, it can specify

whatever datatype it wants. But if the app prints through GDI:

We’ll go RAW in the following cases:

  • Printing to FILE:, directly to port (no spooling)

  • Client disables “advanced printing features”

Additionally, for networking printing:

  • Client is anything other than NT/Win200/XP

  • Client doesn’t use a “true” connection

  • Printing to a “masq” printer (win9x, netware, etc.)

  • Server has “printer attribute RAW only” bit set

  • Server doesn’t accept client’s EMF version

Thanks a lot vivek.

I am trying to narrow down the possibilities here. In my case
the UNIDRIVER based Windows 9X driver creates EMF data
successfully except Microsoft powerpoint. I have tried a many
UNIDRIVER based drivers comes with windows 9x operating system.
None of them takes the EMF data type if the print job is from
power point application.

But I am sure that the power point application prints through
GDI. I have tried a monolithic windows 9x driver, it works fine,
it creates EMF data successfully for Power point too. So my
question is,

why the UNIDRIVER based driver doesn’t create EMF data for a
particular application if the monolithic driver creates EMF data
successfully for all the applications?

Is it a problem with Windows 9x UNIDRIVER?

Or is it possible to fix this in MINIDRIVER?

Thanks,
Sridhar
