The last screen lets you insert a name for your new printer.
The name must start with a letter and may contain numbers and underscores with a maximum size of 128 characters. Stick to it if you want to avoid erratic behaviour of your CUPS daemon. The printer names in CUPS are not case sensitive! This is a requirement of IPP. So the names DANKA_infotec, Danka_Infotec and danka_infotec all represent the same printer.
