English to Italian Tech/Engineering

si tratta sempre di una stampante.

"core" l'ho trovato sempre in altri contesti (anima di un cavo, nucleo magnetico). Ma in questo caso che cos'è 'sto "empty core"?

Ho trovato anche questo, ma non mi sembra sia applicabile:
[GRAF] rocchetto
An unflanged cylindrical reel on which film is wound.

Take-up roller l'ho reso con rullo tenditore.

Alcune frasi:

There are two rollers that can be installed in this position: Take-up
Roller and Take-up Core Roller. The Take-up Roller outputs the media directly from the
Printer, whereas the Take-up Core Roller collects the media onto a core.

Stessa cosa, detta per esteso.
There are two types of Rollers that can be installed in this position, depending on the user’s
application: Take-up Roller and Take-up Core Roller. The Take-up Roller is a rubber roller
that is used in conjunction with the Take-up Pinch Roller. When this roller is installed, the
media is output from the Printer. The Take-up Core Roller is the same as the Feed Roller.
This roller allows an empty core to be installed onto it. When this roller is installed, the media
is gathered onto the core and does not exit the Printer.

Grazie!
