Thanks a lot !

These forms are required by Docuflow, and their names start with the letter "z", so they come in the end of the list, and do not interfere with the other printer form sizes. They are assigned to all virtual printers.

If you do not wish any longer to use Docuflow, you can remove them safely like this

1.  Open the "Control Panel" from the Windows 10 "Start -> Windows System" menu.  Click "View devices and printers" under "Hardware and Sound" from the Control Panel.  Select the printer named "Bullzip PDF Printer" and then click on the menu option "Print Server Properties"
2. 2.  In the "Print Server Properties" window, select the form and press "delete".

These formats are everywhere
