Simlarly, I'm using a Brother HLL2395DW, which replaced my ancient HP 
LaserJet just last August. It's got scanning and double-sided printing, 
plus wired and wifi interfaces. The consumables are reportedly priced 
reasonably, but I haven't needed any yet.


The caveat is that I use and manage it from MacOS and iOS devices. I 
haven't tried a SANE connection.

I am using an HL-2280DW. Wired to my lan and usable for printing and 
scanning from Ubuntu and Kubuntu machines...setup is a little odd but 
once up it works well

I tried typing my password into the user name line and got the expected 
characters. I copied and pasted it into the password line, but it didn't 
help.


I just tried logging in by ssh and had no trouble.

While there I decided to try changing the owner of the html output of 
lshw I did earlier from root to rsteff. Here's the results:


root@ENU-2:/home/rsteff/Desktop# chown rsteff:rsteff hardware.html
chown: invalid group: 'rsteff:rsteff'
root@ENU-2:/home/rsteff/Desktop# groups
root bin daemon sys adm disk wheel audio
root@ENU-2:/home/rsteff/Desktop#

I'm guessing that not being able to log in from ENU-2's own keyboard is 
not related to bad passwords, since I can log in via ssh.


On ENU-1, my Ubuntu 18 machine, when I run groups, I see that my user, 
dick, has a group:


dick@ENU-1:~$ groups
dick adm cdrom sudo dip plugdev lpadmin sambashare vboxusers
dick@ENU-1:~$

Somehow I don't have one on ENU-2, the Slackware machine, for rsteff. 
I'm sure I could add a group, but I'm wondering if the step that should 
have created one included other things that should have happened during 
the initial install. Will that be something I can track down, or would 
it be easier to run the install over again? I'm assuming I could get the 
package files I've created from /tmp before I start over, and save them 
to a USB stick, which would save me some time. This time I would start 
by totally redoing the partitioning, instead of just using the old boot 
partition.


Again, I'm making guesses here, so feel free to apply a clue stick to 
keep me from doing something wrong.

After several minutes I tried closing Firefox using its own close button 
and it worked. However, none of the icons on the XFCE launch (?) bar at 
the bottom of the screen worked. So I went with option two and am 
rebooting. Actually, I powered down and started back up. Now the mouse 
works, but the keyboard does not. Unplugging the keyboard and plugging 
it back in fixed that, but login won't accept my normal user password, 
or my root password.

[PLUG] Color Laser/LED Multifunction Printers?

[Roderick Anderson]

I seem to remember at least two threads last year about printers.

Didn't follow them then but now I am in the market. :-/

All the 'Best of/for' articles aren't helping.

Anyone know of a chart listing features for a lot of the printers?

Heck I'd take recommendations.

LED or laser (not inkjet), color, multifunction ie. scanning (SANE).
Nice would be duplex print and duplex scan would be icing.


TIA,
Rod

Re: [PLUG] Copying all partitions of a drive to single partition/directory?

[Tyrell Jentink]

The standard tool for taking a disk image is 'dd.' Man page:
http://man7.org/linux/man-pages/man1/dd.1.html

Theoretically, you can simply image the entire drive, partitions and all
intact exactly as they are presently, although I've never done it that
way... I have always imaged partitions directly... But I don't see why
either method would be "wrong," as long as you know how to mount the output
;)

As for compressing it...
https://serverfault.com/questions/52260/compressing-dd-backup-on-the-fly
suggests you can simply pipe the output of 'dd' directly into gzip... But
one of the comments says not to use it for the purposes the original poster
suggested it for, so maybe read their warnings before following their
advice.

I like the ease of use of Clonezilla-live. But it intrinsically wipes
