1917734 - Printing fillable PDF results in text much larger than while editing

Status: RESOLVED FIXED

(Firefox :: PDF Viewer, defect)

Description

[Andrew Overholt [:overholt]]

Attachment: pdf that demonstrates the problem

See attached fillable PDF.

Steps to reproduce the problem:

1. enter text, notably in the "Please print name" "Parent/Guardian" box on page 3
2. observe that you can enter a long first and last name (mine will suffice :)

What is the expected behavior? (add screenshot)

• Text you enter fits into the resulting printout

What went wrong? (add screenshot)

• see attached screenshot for the printout version having much larger text

FWIW I tried this in Release on Linux and Nightly on macOS and the result is the same

The field font size is 0 and we don't compute correctly it when rendering the field before printing.
