From long time i am trying to figure out the solution for using our
choice of printer form in Vista!
I had tried all option mentioned on the related forums but in vain.
Lastly i myself kept on trying all the option that are possible, and
voila i got the solution.
Here's the way i got it.
Requirement: Microsoft XPS Documet Writer.
Here you have to define the form size of your choice and name it.
Now open any application and try to open its Print Dialouge Box.
(Where you can issue print command).
Select 'Microsoft XPS Document Writer' as print option.
In preferences of document you might be able to see your defined form
along with other forms. Select that form and hit the print button.
Save the file with name of your choice and exit.
Now you may be able to see the form size you had defined in any
application you might want to work with.
Do try the above trick and see if its working.
Folks if it is, do leave some comments.
