Description Zdenek Dohnal 2018-09-14 07:31:37 UTC 
When I create file device printer on RHEL 7, then the output file isn't in expected location. It is caused by 'PrivateTmp' directive in cups.service, which makes systemd create a private temp folder for cups. 
This behavior is unwanted, because it worked differently in RHEL 6 and Fedora (file was at the exact location as you define in lpadmin command) and it causes a confusion to users and upstream.

Steps to reproduce:
1) install cups
2) enable file devices for cups (put FileDevice Yes into /etc/cups/cups-files.conf and restart cups service)
3) $ sudo lpadmin -p test -v file:/tmp/printout -m drv:///sample.drv/generic.ppd -E
4) $ lp -d test /etc/fstab
5) $ ls /tmp/printout
ls: cannot access /tmp/printout: No such file or directory

Expected results:
$ ls /tmp/printout
/tmp/printout

How to solve:
- remove PrivateTmp from cups.service unit file
