Please add the account type "Printers (PyKota printers)" on tab "Account types" in your server profile and setup the LDAP suffix where printers are stored.
Then add the PyKota printer module on tab "Account modules".
Next you can start managing printers inside LAM. Here you can setup the costs for a print job. LAM will also show if the printer is member of any printer groups.
You can also setup printer groups. Just add some members to your new group.
