'pkprinters' is the command line tool used to manage printers and printers groups in PyKota's DataBase.

Functionnalities :

  - '--add' (or '-a') : Create printers.

  - '--delete' (or '-d') : Delete printers.

  - '--list' (or '-l') : List printers.

  - '--description' (or '-D') : Change the textual description of some printers.

  - '--charge' (or '-c') : Change the price per page and optionally per job of some printers.

  - '--groups' (or '-g') : Manage printers groups (add to with '--add', remove from with '--remove').

  - '--remove' (or '-r') : Remove printers from printer groups (may only be used with '--groups').

  - '--maxjobsize' (or 'm') : Sets the maximum number of pages accepted in a single job on some printers.

  - '--passthrough' (or '-p') : Puts some printers into 'passthrough' mode. In this mode, users are not
    charged and their quota is not impacted when they print on such printers.

  - '--nopassthrough' (or '-n') : Puts some printers into 'normal' mode, i.e. **NO 'passthrough'**. This is   
    the default.

  Printers' names can be passed as non-option arguments at the end of the command line. Wildcard characters 
  like '?' and '*' are accepted when '--add' is not used. When no printer name is passed on the command line, 
  the '*' wildcard is assumed, which means all printers, unless '--add' or '--delete' is used.
