Keep-Out Areas
At times, incomplete printing of text and/or graphics appear because minimum margins are not provided
during label design. The recommended minimum margins, or “keep out areas” are shown in Figure 32.

NOTE: The length of each “continuous” receipt is determined by the data sent to the printer.
Near Field Communication (NFC)
Much like Bluetooth and Wi-Fi technologies, Near Field Communication (NFC) allows wireless
communication and data exchange between digital devices like smartphones. Yet NFC utilizes
electromagnetic radio fields while technologies such as Bluetooth and Wi-Fi focus on radio transmissions
instead.
NFC is a sub-class of Radio Frequency Identification (RFID) technology that is designed for use by
devices within close proximity to each other. NFC technology allows devices to establish communication
by touching or bringing them into close proximity, usually no more than 7.62 centimeters (3 inches).
The printer contains a passive NFC device which contains information that other devices can read but
does not read any information itself
An active device, such as a smartphone, can read the information on the printer’s NFC tag, but the tag
itself does nothing except transmit the info to authorized devices.
Active devices can read information and send data. An active NFC device, like a smartphone, would not
only be able to collect information from NFC tags, but it would also be able to exchange information with
other compatible phones or devices. An active device could even alter the information on the NFC tag if
authorized to make such changes. To ensure security, NFC often establishes a secure channel and uses
encryption when sending sensitive information.
