Print server is no longer reachable

Print server can get unreachable due to some weird network conditions.

To restore correct networking:

1) Connect to print server with PUTTY (refer to print server manual)

2) type the following command

sudo nano  /etc/network/interfaces

3) change file content that must be the following (OF COURSE IP NUMBER MUST BE CHANGED ACCORDING YOUR NETWORK )

 auto eth0
 allow-hotplug eth0
 iface eth0 inet static
 address 192.168.2.77
 netmask 255.255.255.0
 gateway 192.168.2.1
 dns-nameservers 192.168.2.1

Sace changes with CTRL-O then leave editor with CTRL-X

4) Type following commands

  sudo service dhcpcd stop

  sudo systemctl disable dhcpcd

5) Restart networking

 sudo service networking restart

6) If print server is still unreachable, type

 sudo reboot

...after 3-4 minutes the print server will be reachable
