NOTES: 1. To prevent dot displac ement, after cut ting, feed paper approx imately 1 mm {14/360"} or
more before printing.
2. Paper must be fed over 40 mm {1.57"} before cutting if the printer is stopped. This
prevents a possible paper jam.

When the sensor detects a paper-end, the pr inter stops printing.
Printing resumes when paper is installed and the printer cover is
closed.
a) Detecti on method: Microswitch
NOTE: If paper other than the speci fied one is used, the paper roll end sensor may
not work correctly.
3) Roll paper near-end sensor: Detec ts a near-end of a paper roll.
If t he sensor is enabl ed by ESC c 4, the printer stops printing.
a) Detecti on method: Microswitch
b) Near-end adjustment: Can be adjusted by changing the position of the adjusting screw.
Fix ed posi tion #1 (approxim ately 23 m m {0.9"} )

6) Notes on preprinting on the recording surf ac e of thermal paper
When using thermal paper, the recording surface of which has been preprinted, sticking (a
problem of the thermal head sticking to t he surface of the t hermal paper duri ng printing) may
occur, causing faulty printi ng and other problems. It is, therefore, strongly recommended to
avoi d using preprinted therm al paper. I f such paper must be used, conduct prepr inting tests
under the conditions recomm ended by the paper m anufacturer (t ype of i nk/ pri nt condi t ions) and
confi r m that no faulty printing or any other problems occur before you use it for act ual printing.

NOTES: 1. Notes on using the Epson PS-180 power supply unit
If the printing is continuously performed with the high print ratio, the overcurrent
limitation might be operated. Therefore, the printing length must not exceed the
following v alues when printing wit h high print r ation.
Print ratio: Number of dots being ener gized per one dotl ine / Tot al number of dots

2. Notes on using the power supply uni t other than the E pson specified one ( P S - 180)
• The current consumption of this printer is as shown in Figure 1.9.1. User must
consider these values when the user provides the power supply unit other than the
Epson specifi ed one.
Note that the current consumption may increase if the printer is used in a low
temperat ur e or the print densi ty is set to “dark ” .
• The power supply unit with a small power capacity may not operate the printer
correctly.

Power supply specificati ons: US B sel f power supply function
Current consumed by US B bus: 0 mA (provided entirely from the unit)
USB packet size
With Ful l-Speed connect ion: USB bulk OUT ( TM) 64 bytes
USB bulk IN ( TM) 64 bytes
2) Status transmission from printer with US B interface
Wi th this interf ace, the status of the pr inter i s transmitt ed to the host com puter v ia the USB bul k
transmission method.
The USB bulk transmission method is a host-controlled transmission method. Unlike RS232
transmission, it cannot spontaneousl y interrupt data transmission to the host computer.
The printer has a 128-byte status data buff er. Statuses that exceed the buf fer capacity are
cancelled. In order to ensure that there is no lack of status data, it is necessary to
periodically ret rieve status data at the host c omputer.

3.3 Switches and Buttons
3.3.1 Power Button
The power button (a rocker switch) located on the lower right front of the printer turns the power on or
off.
NOTES: 1. Turn on the power only after connecting the power supply.
2. Press the power button after the LED lights go off if the power is turned on immediately
after the power is turned off.
3. If the power is turned off without the execution of the DLE DC4 (fn = 2) command, the
values of the maintenance counter are not updated correctly.
To use the maintenance counter correctly, see Appendix G.
3.3.2 Panel Buttons
1) FEED button: Non-locking push button
[Function] • If you push this button once and release it, the printer feeds paper for one line based
on the line spacing set by ESC 2 and ESC 3. However, paper feed using the FEED
button cannot be performed under the following conditions:
The roll paper end sensor detects a paper end
When the printer cover is open.
NOTE: This button is disabled by ESC c 5.

2) Starting hexadecimal dumping
Open the cover and turn the power on while pressing the FEED button or executing GS ( A
command, then close the cover. The printer first prints "Hexadecimal Dump To terminate
….." on roll paper and prints the received print data in hexadecimal numbers and in its
corresponding characters.
NOTES: 1. If no characters correspond to the data received, the printer prints ".".
2. During hexadecimal dumping, any commands other than DLE EO T do not
function.
3. Insufficient print data to fill the last line can be printed by setting the printer
offline.
3) Ending hexadecimal dumping
Hexadecimal dumping ends by turning the power off, pressing the FEED button three times, or
resetting the printer after printing has finished.
<Printing example>
Hexadecimal Dump
To terminate hexadecimal dump,
press FEED button three times.

3.9 Cover Open Sensor
The cover open sensor monitors the printer cover. When the sensor detects a cover open during
printing, the error LED flashes and the printer stops printing. The printer recovers when the cover is
closed. When the sensor detects a cover open while the printer is in the standby status, the printer
goes offline. The printer recovers when the cover is closed.
NOTE: Whether the cover is open or not does not affect the status reported by the roll paper end
sensor.
3.10 Print Buffer-full Printin g
• When printing in standard mode
When subsequent data is received after the printer processes one line of data in the print buffer, the
printer automatically prints the processed line and feeds the paper by one line (in standard mode).
• When printing in page mode
When subsequent data is received after the printer processes one line of data in the print buffer, the
printer automatically moves the printing position to the line after the processed one.

6.2 Explanation of Terms
1) Real-time command
Real-ti me commands are identified with a DLE extension such as DLE EOT, DLE ENQ, or DLE
DC4. The printer execut es t hese commands as soon as they are received.
2) Obsolete command
Obsolete commands are commands that will not be support ed by future printer models.
Therefor e, we recomm end r eplacing them with m ore recent, upward-compatible commands that
have t he same funct ions.
3) NV memory write command

4) ESC/POS Handshaking Protocol
ESC/POS Handshaking Protocol is a handshaking protocol between the host com puter and the
printer when the printer transmits data. The ESC/PO S Handshaking Protocol is required i f the
following commands are execut ed:
GS ( L / GS 8 L <some functions>
5) Print buff er
The print buff er is used to store im age data for printing

• Do not embed this comm and within another command.
For example: Gr aphic data might i nc lude this command.
• Transm it thi s command using the fol lowing method:
• When t his command is transmitted, the data following m ust not be transmitted until

In this case, the data fol lowing must not be transmitted until the all status is received.
If t his comm and is transmi tted without usi ng the above method, t he status may not

[Notes] • Frequent write command execut ions by an NV memory write command may damage
the NV memory. Ther efore, it is recommended to wri te to the NV memory less than
10 tim es a day.
• If the power is turned off or the printer is reset via an inter face while this command is
being executed, the pri nter may go into an abnorm al condition. Be careful not to
turn the power off or let the printer be reset via an interface while this command i s
being executed.
• Whil e pr oc essing t his command, the pri nter is BUSY while writing t he data to the NV
memor y and stops receiving data. Therefore, be sure not to transmit data, incl uding
the real-t ime commands, while the print er is BUSY.
• When <Function 48, 51, or 64> is transmitted, the data following must not be
transmitted until the status is received. And, it will be necessary to perform the
ESC/POS Handshaking Protocol procedures when using <Function 64>.
