Creality Ender-3 V3 SE, 3D printer (black)

ADF means automatic document feeding. This is implemented by means of a special scanner cover where it is possible to place several pages at once, for example, a pack of copied or scanned documents.

Double-sided printing that is quite often implemented as a semi-automated function which means that the printer prints one side of the page and then the user has to put all the pack of print-outs in the feeder manually.

There can also be Duplex printers that are able to turn the page during the printing process. Prior to buying the printer you should read the detailed specification about how the Duplex function is implemented.

An option to place a printed document in the feeder and copy it.

A possibility to connect the device to the phone line and phone for sending and receiving fax messages.

A possibility to place a printed paper in the feeder and to receive a scanned document in the computer as a file.

A very useful function if the printer is used from various computers connected in a network. If there is LAN connection it is possible to place the printer at any place where the network and power connection is available and to produce print-outs from any computer without the necessity to connect the printer to any particular computer and to maintain this computer switched on.

This is an obsolete standard and required only in few cases when a company uses DOS software that cannot print from any other ports except LPT. This type of connection is very slow, therefore in most cases a printer with LPT has also the much faster USB or LAN connection.

The most stable, convenient and fastest connection of the printer if the printer is located close to the computer and is used for printing from one computer. The USB connection slot is available with almost all portable computers and desktop computers.

A possibility to connect this printer to the computer via the Bluetooth wireless connection. Usually this type of connection is available for portable computers of average or expensive category. Desktop computers usually do not have the Bluetooth, therefore it will be necessary to buy a low priced USB Bluetooth transmitter for being able to use this functionality.

An excellent way of connecting a computer within a wireless network if you use exclusively wireless network connection at home or at office or if the printer is placed at a location where it is not possible to connect a LAN cable.
