PDF write font size issue

[visstxg]

I am creating a PDF using pyPDF. FRA F 6180.150.pdf This is the input file.

After writing in some of the fields like paragraphs font size getting too big and text is not displaying completely on the field.

Below is the output file

202312532_2024-05-06.pdf

Also one more issue in the same file is I am encrypting the writer pdf with User access permission for PRINT only. With PRINT only UAP the fields are READ ONLY, but there is a Signature field which looks like editable but not able to click or add signature in the file.

Any solutions for these issues Thank you
