PDF/X option missing in PDF Architect 4 printer settings for Word doc

According to the PDF Creator information on the pdfforge website, it supports printing to PDF, PDF/A, PDF/X.
However the option for PDF/X is missing when attempting to print.  Can someone please provide help in resolving this issue.
Thank you!

Hi,

there is no inbuilt profile for PDF/X, but you can still select it as output format during the print job or create a new probfile with PDF/X as default output format.

best regards,
