Photoshop CS6 no print (photoshop has stopped working)

Salve!

I have a problem with Photoshop CS6 ver 13.01 x32.
I am a hardware technician.
One of my customers broke the printer.
I installed a new Utax 2506ci.
The printer works correctly and prints from any application.
Unfortunately, opening a file created previously with Photoshop and trying to print it with the utax, photoshop crashes (photoshop has stopped working and closes).
If the customer creates a new file, print correctly.
If the customer opens this file and copies the contents to a new photoshop file, print correctly.
We have the same problem on 2 different PCs of two different users.
The customer can not recreate all the previously saved files, they are thousands !!!!

Thank you
