Hello Jacob and all guys involved,

I was trying to export PDFs using a Print Entity module but i failed. Drupa gave me following error statement

Error generating document: Missing dependencies. Please install with: composer require "dompdf/dompdf 0.8.0"

Do you have any easy / safe advice to fix this error?
Thank you.
_
I am running the latest Drupal 9.

You need to configure the Entity Print module and a PDF engine.

unfortunately that guide is not very user-friendly for noobs like myself and none of them seems they can not solve this error for Drupal 9:

  • WkHtmlToPdf - i have tried to download / install recommended binary (Win 64bit), but did not work / is supported in Drupal 7 and Drupal 8
  • Dompdf - supported in Drupal 8 only
  • TCPDF - supported in Drupal 8 only
  • mPDF - The mPDF library has been reviewed and decided against adding it to this project, as Dompdf provides a much better implementation
  • HTML2PDF - did not work as expected with Drupal 8

I think Entity Print module is supported in Drupal 9.

You might be running into #3169624: Entity print not supports Dompdf 0.8.6 and need to downgrade via composer require 'dompdf/dompdf: 0.8.5'.
