Zebra Printers incompatible with Rave?

[borland]

I use Rave code based report for flexibility. Is excelent... but...

I print in any printer fine, but in Zebra printers raise error:

invalid floating point operation.

Printing from Word or Delphi program using QuickReport is not problem.
I use:
update Zebra drivers
Rave 6.5 for Delphi 2006.

Any solution? Please.
ThankŽs

Zebra printers are notorius for having buggy drivers. I would say that 98
percent of issues with drivers are Zebra.

Rave simply makes api calls to the printer driver. These calls work just
fine in most printer drivers, as you have noticed. The fact that you can
print to the printer using Word doesn't really help since all this means is
that they aren't calling the particular api that we are. This may explain
why the printer driver doesn't support whatever api we are using. They only
tested with Word and their driver worked just fine so they stopped
development.

Most often when issues are reported we can do a test and we find that we can
print to file through the printer driver just fine. This means that we are
calling valid api's. The problem comes in when the driver tries to convert
these api calls to valid printer calls. That's when the error occurs and
there isn't anything that Rave can do about that.

On some occasions I have traced the issue down to the setting of a
background color or something just as simple. (I don't remember the exact
issue, but it was something that certainly should not have been a problem.)

I understand your x. But i print ok in Delphi 7 with Rave. Then Zebra
Drivers is ok?
Is posible use Rave version from Delphi 7 in Delphi 2006?
My test is print "Hello world". Is very simple.

Sorry, but i need a solution. I migrate all my application to Delphi 2006.
