Samsung M2070 CUPS internal server error

[gimble guy]

I tried many different ways to install the Samsung M2070 Printer, USB and Network. But I get CUPS internal-server-error or something like that.

I'm using the latest LinuxLite. Firewall is disabled

I also have a Samsung network printer, model M4070FR,
and have finally figured out a simple way to get it and the built in scanner to work.

First of all, to get the scanner to work, in the printers menu, select network,
ipv4, change from DHCP to static and give your printer a static address.
Then edit as root, /etc/sane.d/xerox_mfp.conf  and add the line
tcp 192.168.x.xxx  the x should be either a 1 or 2 depending on
your router's address, and the xxx is the static address you give the printer.

To install the printer:

Go to printers in the LL menu, add new printer, click on network printers, select your printer,
select postscript.Samsung, select generic driver, select postscript, then OK.

That should install the printer using the generic cups drivers and
you won't have to mess with installing Samsung drivers.

On MXLinux, it automatically setup the IPP everything is automatic. Not sure why the CUPS is like this in Linuxlite

here's the syslog:

here's the output why running the system-config-printer software:

So finally  :57: After installing the Samsung Linux Drivers, and I also stole the M2070PPD file from my MXLinux install. With these two combination noodles, I finally got my Samsung M2070FW Printer and Scanner working in the Network. All DHCP. OMG I am so happy. But please if someone out there can fix the CUPS to work properly like in MXLinux does. I would really appreciate it.

Peace!
