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.

https://127.0.0.1:631/printers/B4350 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
<nothing>

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
<nothing>

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.
