Can't print to lp0 [closed]

Hi All,

Help! I can't get my billing out and need to get some food on my table.

Fedora 29

cups-1:2.2.8-10.fc29.x86_64 cups-client-1:2.2.8-10.fc29.x86_64 cups-filesystem-1:2.2.8-10.fc29.noarch cups-ipptool-1:2.2.8-10.fc29.x86_64 cups-libs-1:2.2.8-10.fc29.i686 cups-libs-1:2.2.8-10.fc29.x86_64

Did my dnf updates and now I can not longer print to lp0.

I fired up a Live USB, also Fedora 29, and I can print, so it is not my hardware. (It is not program dependent either.) And then did my updates on the flash drive and now it can't print either. tells me "Processing since". I can cancel jobs.

This is the error message I am getting:

Mar 8 14:47:02 rn6 dbus-daemon[1033]: [system] Rejected send message, 0 matched rules; type="method_return", sender=":1.6" (uid=70 pid=1044 comm="avahi-daemon: starting up " label="system_u:system_r:avahi_t:s0") interface="(unset)" member="(unset)" error name="(unset)" requested_reply="0" destination=":1.356" (uid=500 pid=6153 comm="/usr/bin/leafpad " label="unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023")

Downgrading cups and using prior versions of the kernel does not help.

Fresh reboot:
lsof | grep lp0

After sending a CUPS test print
$ lsof | grep lp0
parallel  11981                      lp    5w      CHR 6,0       0t0      26621 /dev/lp0

After removing the CUPS test print
$ lsof | grep lp0
parallel  11981                      lp    5w      CHR 6,0       0t0      26621 /dev/lp0

$ kill -9 11981
 lsof | grep lp0

So is "parallel" the culprit?

How do I fix this?

Many thanks, -T

Moderator. Would you remove the duplicate post?

I really did not mean to send this twice. The first send told me I was missing stuff and had to fill it out. But it apparently sent anyway

Done! Thanx for asking.

Thank you ! Are you able to remove it completely?

Maybe, but there's no need. People will just ignore this question, and in a few hours it won't show up any more.
