We can setup a network printer with an ethernet port to our lab and be able to print from every client PC. Printers without cable connection are not recommended.

Our network printer has 2 possible ip configurations, auto get ip from dhcp or static ip

1. If it is already set up with a static ip, we need to change it to auto get ip from dhcp. It probably has an LCD screen with configuration, so we set ip to auto from its LCD screen.
2. We start LServerAdmin application
   1. We go to menu Services/ Basic Services / Dhcp Server / Configure / Static IPs / Add.
   2. On automatic scanning it shows up all the dynamic IPs of the PCs and devices connected to our network, with a description to help us locate the printer. We can verify the dynamic ip from our printer LCD screen settings or by opening a browser on another client PC typing the ip on the browser address. We continue and select it and press OK.
   3. On next dialog Enter ip and host name of device we type
      • IP Address : 192.168.10.10
      • Hostname : myprinter (whatever name we want)
      • MAC Address : (leave as is)
   4. We shutdown and restart the printer to get the new ip. With have configured our printer to always get the same ip 192.168.10.10 from dhcp server.
   • We have finished printer network configuration.

If we want to setup a 2nd printer we follow the same steps as above and can set ip as 192.168.10.11

Our network printer can be installed on windows virtual machine, so that we can print from any PC booting from network.

1. We connect to Windows virtual machine from proxmox (not from a client PC).
   • We connect with our personal network account with administrative priviledges on Windows.
2. We install the network printer on the windows virtual machine downloading its installation software from the internet (see Install Windows software)

Our network printer can be installed through cups on server on address http://lserver:631 with the root user of lserver vm and password. It must be set as shared. Client PCs running Linux will automatically see the printer. Any connected users might need only to logout and reconnect.

After initial installation, all users have the ability to print. If we want to give permissions to print only to teachers or individual users, we do the following:

1. We connect to Windows virtual machine from proxmox (not from a client PC).
   • We connect with our personal network account with administrative priviledges on Windows.
2. We go to Control Panel / Hardware / Printers. We click on the printer and select Manage
3. We right click on the printer and select Properties . and go to Security
4. To remove permission for everyone to print we select Everyone group and click on Remove.
5. To give permissions only on teachers
   1. We click on Add
   2. If we don't want to show all users, we click on Object types, select only Groups and press OK.
   3. On field Locations we leave our domain e.g. SCH.LOCAL
   4. We click on Advanced and then Find now
   5. We select the group teachers, click OK and again OK.
   6. It should show group SCH.LOCAL\teachers on the list with Group names or users with permission to print.
6. We click on Apply and ΟΚ and leave from Security tab.

• To give permissions only to specific users, we do the same procedure but in step 5 on Object Types, we select Users and from the list we select the users we want.
