win32 application won't print on w7 x64

[HipHoper]

Hi,

Just installed a W7 pro x64 for a client on a new machine, And managed to install an old xp program (it's an old client database for optometrists - something from the late 90's).
The program required me to run it's setup (I ran it as admin in xp sp3 compatibility mode), And also require to copy LEAD TOOLS dll's and Ocx's to \\syswow64 folder.
The program works fine, But for some reason I can't print to local or networked printer. I tried even printing to a virtual pdf printer (Dopdf 7), But it just does not print.
Printing test pages and printing from other program works fine.
I'm afraid it has to do with the fact that the system is 64 bit based and therefore it's printing drivers too.
The only thing I thought to do is to connect an old computer they had and use it for printing only (THey need to print once every few days from this program).
I also thought about the option of running the program on SBS 2003 which they use as a file server.
What do you suggest ? any workaround ?

Thank you

Update :

Installed the software on winxp 32 bit and windows 7 32 bit and it seems not to print at all - when i use dopdf and regular printer.
I guess this software is a goner

What does/doesn't happen when you try to print? Any error messages/print jobs stuck in the print queue etc?

How certain are you that its a Win32 app verses being a DOS app?

Is there a pc in the office where it is installed and prints OK? If so, seek out the Autoexec.bat file and see what's in it.
