A follow up on https://lists.CentOS.org/pipermail/CentOS/2020-July/351009.html In addition to page size problems I just found out that page-ranges option is ignored. To reproduce I created a two page PDF file and printed it like
lp -d printer_name -o page-ranges=1 twopage.pdf Two local printers, HP and Canon output two pages. Printers were configured using CUPS UI by selecting the appropriate USB printer, then manufacturer and then PPD from a list of models. If I move printers to a Fedora 32 system they print correctly. Upgrading CentOS7 CUPS server from 1.6.3 to latest 2.3.3 had no effect. I wonder what else needs to be updated to resolve this problem.

Thank you.
