Selected page size is not followed.

  • Google Chrome follows the selection and generates the PDF accordingly.
Print Settings might vary from printer-to-printer or server-to-server.

Capabilities vary per printer or server. These capabilities are queried when adding the printer or server.

  • Some of the settings are used to generate the print job upon submission, while some are not applied until it is printed.
