Epson PRP-080 user manual Reliability, Environmental Conditions, Installation, Interface

1.7) Reliability

1. Life Span:	Mechanism: 15,000,000 lines
	Thermal head: 100 million pulses, 100 Km
	Auto cutter: 1,500,000 cuts
	(End of life span is defined to have reached
	the end of its life when it reaches the
	beginning of the Wear out Period.)
2. MTBF:	360,000 hours
	(Failure is defined as Random Failure
	occurring at the time of the Random Failure
	Period.)
3. MCBF:	52,000,000 lines
	(This is an average failure interval based on
	failures relating to wear out and random
	failures up to the life of 15 million lines.)

1.8) Environmental Conditions

1.	Temperature:	Operating: 5 to 45C (41 to 113F)
		Storage: -10 to 50C (14 to 122F)
		(except paper)
2.	Humidity:	Operating: 10 to 90% RH
		Storage: 10 to 90% RH (except for paper)

NOTE: If the printer is not used for a long time with paper installed, some part of the printing may be light due to the deformation of the paper. If the printer is not used for a long time with paper installed, be sure to feed paper approximately 30 mm before printing

3. Acoustic noise (Operating):	When using auto cutter Approximately 50
	dB (Bystander position) When not using
	auto cutter: Approximately 40 dB
	(Bystander position)

1.9) Installation

The PRP-080P series printer must be installed horizontally. (Vibration during paper cutting and using a drawer should be considered. Take measures to prevent the printer from moving. Affixing tapes are provided as an option.) An optional hanging bracket can attach the printer to a wall. (Following the procedures describes in the installation manual, install the wall mount and change the location of the paper roll near-end sensor, then install the paper roll stopper and other parts.)

2. CONFIGURATION

2.1) Interface

a. RS-232 serial interface

a.1) RS-232 Specifications

1.	Data transmission:	Serial
2.	Synchronization:	Asynchronous
3. Handshaking:		DTR/DSR or XON/XOFF control
4.	Signal levels:	MARK = -3 to -15 V: Logic "1"/ OFF
		SPACE = +3 to +15 V: Logic "0"/ ON
5.	Baud rate:	4800, 9600, 19200, 38400 bps
6.	Data word length:	8 bits
7.	Parity Settings:	None
8.	Stop bits:	1 or more
9.	Connector (printer side):	Female DSUB-25 pin connector

NOTE: The data word length, baud rate, and parity depend on the DIP switch settings.

The stop bit for the printer side is fixed to 1.

a.2) Serial interface connection example

Printer Side DB-25 POS RS-232 Connection DB9

NOTE: Set the handshaking so that the transmit data can be received. Transmit data to the printer after turning on the power and initializing the printer.
