I tried to print a T5018 slip for my client and got a message saying "The printing of pre-printed forms is currently unavailable...".  I have never set any of my forms to "Pre-printed Form" and have not used pre-printed forms in over 20 years.

When I looked under Slips Print Setup, I discovered that all of the forms' Copy 1 are set to "pre-printed form".  When I selected the form to change this, no options were available under "Form Type" (the text is greyed out and the down arrow does not provide any options).

I then tried selecting another slip type (under Slips Print Setup) and any time I selected a slip type (Copy 3/4 or Slip Notes for example), the form type changes to "Pre-printed Form" with no ability to change the "Form Type".

Now when I go to print the slips I get the following error:

Unhandled exception has occurred in a component in your application.  If you click Continue, the application will ignore this error and attempt to continue.

Index was out of range.  Must be non-negative and less that the size of the collection.

Parameter name index.

The details provided are way too large to type in here.

When I press continue, it goes back to the print dialogue box, but all I can do is cancel the print job (it will not allow me to print the forms).

If I use a computer with no changes to the Print Slips Setup I am able to print the slips (other than Copy 1 which also shows the Form Type as "Preprinted form" there as well).

I was in 2020 FX, but the same problem is occurring with the other years of FX as well.
