Printing

Printer management rights

To allow a user to perform management operations (add, remove, …) on a printer, he must be given the corresponding privileges.

This is done as the root user by using the command:

net -U root -n netbiosname rpc rights grant admin SePrintOperatorPrivilege

However, it is not always possible to identify with Samba as root, because Samba can be configured to use an LDAP directory in which the root user is missing. In this case, changes must be made directly to sam instead of going through an RPC call:

net sam rights grant admin SePrintOperatorPrivilege

Adding a printer

To add one or all the printers while associating the CUPS driver:

cupsaddsmb -U admin -H printers -v garfieldPrinter name    # Adding the printer: garfield
cupsaddsmb -U admin -H printers -v -a          # Adding all the available printers

Be careful to the printer name and its case, a difference in case with the name entered in CUPS will result in installation problems on some versions of Windows.

Deleting a printer

rpcclient -U admin printers -c 'deldriver garfieldPrinter name'

Printing

It is possible, although a direct access to CUPS is generally preferred, to print from Unix using the Samba client. To do this, run the following command:

smbclient -I printers.example.com //printers/queue -c 'print -' < my_file.ps

Miscellaneous

Shows the file ACLs

This is useful when the zfsacl module is stacked and we want to see the result of the ACLs created on the Unix file system:

getfacl my_file.txtFilename
