Printing failure -

[Bob Goodwin]

Earlier today I discovered that I could not print from this Fedora 32. 
It has always printed without a problem. The printer is Ethernet 
connected to my LAN. I have gone through the setup with cups, the 
fedora/gnome admin app, and now the Brother liinux install tool.

Cups shows:
HLL5100DN http://localhost:631/printers/HLL5100DN 	HLL5100DN 	
    Brother HLL5100DN for CUPS 	Paused - "could not create directory 
"/root/BRF": Permission denied"

The Brother install tool quits when it tries to make a test print and 
finds it can't see the printer:

lpadmin -p HLL5100DN -v cups-brf:/ -E
Test Print? [y/N] ->y

wait 5s.
lpr -P HLL5100DN /usr/share/cups/data/testprint
ls: cannot access '/etc/udev/rules.d/*.rules': No such file or directory
ls: cannot access '/etc/udev/rules.d/*.rules': No such file or directory
Hit Enter/Return key.

I began writing this yesterday, this morning we tried and were able to 
print from a Mac portable via wifi so that says the printer works at 
least. Something is corrupted in my computer it appears?

And doing "ctrl p" fails with:

Any thoughts on what to do?            Bob

I had problems printing to my networked Brother printer, the only
thing I found to get it printing was to disable SELinux.

But it is a "bad thing"(TM) to disable selinux. selinux should be
producing alerts, which  you could use to fix or at least "solve"
the problem without totally disabling it.

I had not thought about SELinuxbut seteforce 0 does not help. Thanks for 
the idea ...

Has it ever worked in Fedora 32?  There was a bug where mDNS was
removed from nsswitch.conf when I upgraded to F32 that broke printing
for me until I added it back.

Yes, it has worked since the FC32 was installed using the Brother tool 
for the printers, dunno when it stopped but it would be less than a week 
since I needed it, I print some crossword puzzles weekly which led to 
finding it failing.

I have Centos-7 on a little acer netbook, with the brother drivers for
our DCP-7065. Every once in a while it stops working (with no errors
that I've found). when that happens I remove the drivers and reinstall
and we're good again. I'm guessing that something that comes down in an
update clobbers something that Brother's installer changed.

° Yes, I did that yesterday, twice actually, it is always the same 
'print' never finds the printer. Anything else I've  used shows it? 
Probably some damage done while working on another problem I suspect ...

and I neglected to mention that I've never seen that issue on any OTHER of
my Centos systems. Go figure.

Well, looking at this thread, Kevin mentioned"

"There was a bug where mDNS was removed from nsswitch.conf when I upgraded to F32 that broke printing for me until I added it back."

Have you added it back after working on the samba issue?

grep ^host /etc/nsswitch.conf

No I have not and looking at this I'm not certain if it is there or not:

[bobg@WS1 ~]$ grep ^host /etc/nsswitch.conf
<font color="#FF5555"><b>host</b></font>s:      files dns myhostname

It is *not* there....

Go back and edit /etc/authselect/user-nsswitch.conf and then run "authselect apply-changes"

You want /etc/authselect/user-nsswitch.conf to contain....

hosts:      files mdns4_minimal [NOTFOUND=return] dns myhostname

Ok, I did as you say. I will re-install the printer and let you know 
when it works. Probably tomorrow ...

Thank you,         Bob

OK, and do verify that the changes were made to /etc/nsswitch.conf.  Just because paranoia is
at times not a bad thing.  :-) :-)

I did that immediately after activating the change.

The important thing is that I am able to print and satisfy the need for 
crossword puzzles ...

Thanks for the help

I got my Brother DCP-L2550DW while I had F31. After I upgraded to F32 I realized I could not print, tho the printer still showed up as being there. The note that I wrote while fixing it is now in my "howto upgrade my Fedora" notes...

Had to re-install Brother printer stuff:
cd /home/doug/download/installed/Brother-printer
sudo ./uninstaller_brscan4
sudo ./uninstaller_brscan-skey
sudo ./uninstaller_DCPL2550DW

sudo ./linux-brprinter-installer-2.2.1-1
Input model name ->DCP-L2550DW
OK? [y/N] ->y
Will you specify the Device URI? [Y/n] ->Y
13 (I): Specify IP address.
select the number of destination Device URI. ->13
 enter IP address ->192.168.100.152
Test Print? [y/N] ->y

Test was good.
