How to set font style for print format

how to set font style for print format (PDF/PRINT)…please help

  1. I have created the desired Print Format to be printed using the Browser’s print dialogue.
  2. However, I could not streamline the Print Format’s CSS font settings when I used the PDF Generator , such as : api/method/frappe.utils.print_format.download_pdf.
  3. I have already tried adding “hostname” to site_config.json

You can adjust the .CSS settings in the file/header to use your preferred font and/or styles
