Looking at the document, which is an article from a medical journal, it contains an embedded TrueType font WenQuanYiZenHei so it should not default to any font on my CentOS 7 system. Further, a colleague using a Mac is able to print the very same document at higher quality than I am (not sure what printer she has though). Thus, I am leaning towards a printer driver/printer problem on my system. _______________________________________________ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
