Both claim that the printer was deleted, but it doesn't go away. Cups logs: localhost - root [21/May/2017:08:58:17 -0400] "POST /admin/ HTTP/1.1" 200 103 - - localhost - root [21/May/2017:08:58:17 -0400] "POST /admin/ HTTP/1.1" 200 2329 - - localhost - root [21/May/2017:08:58:18 -0400] "POST /admin/ HTTP/1.1" 200 126 - - localhost - - [21/May/2017:08:58:18 -0400] "POST /admin/ HTTP/1.1" 401 142 CUPS-Delete-Printer successful-ok localhost - root [21/May/2017:08:58:18 -0400] "POST /admin/ HTTP/1.1" 200 142 CUPS-Delete-Printer successful-ok localhost - root [21/May/2017:08:58:18 -0400] "POST /admin/ HTTP/1.1" 200 996 CUPS-Add-Modify-Printer successful-ok localhost - root [21/May/2017:08:58:18 -0400] "POST /admin/ HTTP/1.1" 200 199 CUPS-Add-Modify-Printer successful-ok localhost - root [21/May/2017:08:58:18 -0400] "POST /admin/ HTTP/1.1" 200 2072 - - But again, despite the "CUPS-Delete-Printer-successful-ok", it's not actually deleted. In system-config-printer, when I try this multiple times, I _might_ see the printer briefly disappear from the printer listing, but then it comes back. Other printers I create to test what's going on here, I am able to delete. Just not this one. I will attach my /etc/cups/printers.conf.
