Konsole "Print Screen" to PDF file - set default paper size and margin sizes

I’m using Fedora 39 w/ the KDE spin:

  • KDE Plasma version: 5.27.9
  • KDE Frameworks Version: 5.111.0
  • Qt Version: 5.15.11

When using the Konsole app, and when printing a Konsole session’s contents to a PDF file, the Konsole app always selects, by default, the paper size A4, and it always specifies, by default, absurdly small page margins (~4 mm).

  • File menu > Print Screen… (Ctrl+Shift+P)
  • Printer Shell dialog > Name > Print to File (PDF)
  • Printer Shell dialog > Properties
  • Printer Properties dialog > Page tab
  • Page size: A4
  • Margins: 0.14 in (all sides)

In KDE’s System Settings > Regional Settings > Region & Language, the Paper Size option is set to Letter and all other settings are configured for American English.

How do I change/specify the default settings for (a) the paper size (this should be Letter not A4) and (b) the page margins (e.g., 0.75 inch)?
