Chapter 2 Setting up the printer
Ethernet terminology and default setup
For the printer to operate with Ethernet, a series of commands must be set within the printer. These
commands can only be set through the host computer and are not configurable through the printer
configuration menu.
Default setup instructions and a sample Ethernet diagnostic printout are shown below. Note the differences
between an Ethernet and a standard RS-232C printout.
Ethernet terminology
Before making command settings, review the following description of terms to fully understand their
intended meaning.
MAC address
A unique hexadecimal serial number assigned to each Ethernet network device to identify it on the network.
Each printer communication board gets a unique number from an assigned range of numbers. Numbers start
with: 00:E0:70.
IP address
A unique number that identifies each node on a network and to specify routing information. Each node must be
assigned a unique IP address. The address is made up of two distinct parts: a network ID, which identifies the
network; and a host ID, which is typically assigned by the administrator. These addresses are typically
represented in dotted-decimal notation, such as 138.58.11.27. The default setting is: 192.0.0.192
Net mask
A series of bits designed to "mask" certain portions of an IP address and is used primarily for subnetting. The
standard netmask for a Class C network is 255.255.255.0, with the last octet (.0) directing the host to look
there for the machine number. The rest (255) is the network number. The default setting is 0.0.0.0. The net
mask is used to determine if a gateway is needed to reach an address.
Gateway
A hardware or software set-up that translates between two dissimilar protocols. A gateway, even when the
printer is on another subnet, is not always needed. The printer initiates no connection and obtains the gateway
address from the host packets. The default setting is 0.0.0.0 (none)
HTTP
An application protocol for connection to the Internet. With HTTP, the printer’s Ethernet settings can be
configured with a Web GUI. The HTTP server listens on port 80. The default setting is to have HTTP enabled.
Raw TCP/IP Port
Enables the printer to listen for raw TCP/IP communications. Specifying this to zero will disable raw TCP/IP
connections. Default value is 9001 enabled.
DHCP
Allows "leasing" of IP address for a limited time. If no IP address is found at start-up, the printer waits for two
more minutes. If no address is found after two minutes DHCP will automatically set the default IP address.
Default: enabled
Ethernet default setup
To return the printer to the default settings, put the printer in the boot mode and hold down the feed switch
until you hear the high-low-high tones (about 10 seconds).
The default settings are:
DHCP Enabled
Default IP 192.0.0.192 (in use after 2 minute Bootp time-out)
Net mask of 0.0.0.0 (causes default mask of selected IP to be used)
HTTP Server Port 80 active
Raw TCP/IP Port 9001 active
Sample diagnostic printout of an Ethernet printer:
Ethernet terminology and default setup
11
The circled area on the printout above shows Ethernet settings. These settings can not be changed through
the configuration menu and must be set by sending commands from the host. See Ethernet setup commands
on page 35.
Testing the printer
If the printer is functioning normally, it will beep once. If it responds differently, refer to Troubleshooting
on page 24, or contact your regional HP authorized service provider for HP Point of Sale System products.
12
Chapter 2 Setting up the printer
The printer will arrive for installation pre-configured. The printer’s current configuration appears on the test
(diagnostics) printout. However, if you would like to run a new print test or check the configurations, you can

Operating the printer
Configuring the printer
The configuration menu allows you to set general printer parameters. The test prints the diagnostics form,
which details settings for all functions. The printer will partially cut the paper between each variation.
The test ends with a partial cut of the paper. A complete test printout may require the use of several feet of
paper.
Since the printer is usually shipped pre-configured, most users do not need to change the configuration of
the printer. If you make adjustments to the configuration, be careful not to inadvertently change settings
that may affect the printer’s performance. HP does not recommend that users change the printer
configuration.
NOTE: The printer is shipped with a test printout that includes the preset configuration. If you run into
problems after changing the printer configuration, use the settings as a default.

When to change the receipt paper
Change the paper when it is near the end of the roll or out. When the paper is low, you will want to monitor
usage to avoid running out part way through a transaction. When the paper is out, you must load a new roll
immediately or data may be lost!
When paper is low:
●
Colored stripe appears on the receipt paper, (if paper is purchased with stripe) and indicates enough
paper remains for a small transaction.
●
The green LED flashes slowly indicating that approximately 4.5 meters/15 feet of paper remains. If too
much paper is left on the roll, the “paper low” setting can be adjusted by entering the configuration
menu and changing the “paper low” extension setting.
When paper is out:
Green LED flashes quickly indicating the paper must be installed.
CAUTION: Do not try to operate the printer or POS computer if the printer runs out of paper. The printer
may continue to accept data from the POS computer even though it is unable to print. Data may be lost as a
result.
For instructions on how to change the receipt paper, refer to Loading or changing the receipt paper
on page 6.
NOTE: When changing the type of paper being used, you must set the printer to the new paper type. This is
done through the command 1D 81 m n or through the configuration menu (refer to Entering the configuration
mode for model A799 on page 15.
Paper type grades
●
Type 0: Monochrome
●
Type 4: Two-color
Setting the printhead
The printhead energy rating and printer setting must match. The setting will be preconfigured from the
factory but may require changing if service to the thermal mechanism is required. The “Head Setting” on the
diagnostic printout must match the letter marked on the front right of the thermal mechanism. Whenever the
thermal mechanism is replaced, if the letter on the mechanism is different from the head setting, you must
enter the configuration menu and set the printhead to match. Contact an HP authorized service provider to
replace the thermal mechanism.
Preventing printhead overheating
There are restrictions on the duty cycle because of the heat generated by the thermal printhead when
printing solid blocks (regardless of the length of the block in relation to the print line). The restrictions are
ambient temperature, the percentage of time (measured against one minute) of continuous solid printing,
and the amount of coverage.
Keep in mind that the ambient temperature may be affected by factors such as direct exposure to sun or
close proximity to heating elements.
20
Chapter 3 Operating the printer
CAUTION: When the duty cycle exceeds the limits shown in the following table, the receipt printhead will
heat up and shut down. This may damage the printhead.
To avoid this problem, do one or a combination of the following:
1.
Reduce the amount of dot coverage.
2.
Reduce the time of continuous solid printing.
3.
Reduce the ambient temperature.
Allowable duty cycle (measured over one minute of continuous printing)

resulting in 30 seconds of printing and 30 seconds without printing.
For reference:
●
A typical receipt with text (contains some blank spaces) is approximately 12% dot coverage.
●
A full line of text characters (every cell on the line has a character in it) is approximately 25% dot
coverage.
●
Graphics are approximately 40% dot coverage.
●
Barcodes are approximately 50% dot coverage.
●
A solid black line is 100% dot coverage.

Maintenance guidelines
Cleaning the printer
Clean the outside of the cabinet as needed to remove dust and finger marks. Clean the printer cabinet and
paper bucket with a clean, damp cloth moistened with Isopropyl alcohol.
CAUTION: DO NOT use denatured alcohol or any other form of alcohol other than Isopropyl alcohol to clean
the printer cabinet or paper bucket.
The cabinet materials and finish are durable and resistant to the following items:
●
Cleaning solutions
●
Cooking oils
●
Lubricants
●
Ultraviolet light
●
Fuels
Cleaning the thermal printhead
CAUTION: Do not clean the inside of the printer with any cleaner. Do not allow cleaning spray to come in
contact with the thermal printhead. Damage to the internal electronics or thermal printhead could occur.
NOTE: The thermal printhead does not normally require cleaning when recommended paper grades are
used. If non-recommended paper is used over an extended period, attempting to clean the printhead will
have little effect on the print quality.
1.
Turn off the printer and POS computer.
2.
Unplug the printer from the POS computer and the cash drawer, if connected.
3.
Wipe the printhead with a cotton swab moistened with Isopropyl alcohol.
CAUTION: DO NOT use any other form of cleaner other than Isopropyl alcohol to clean the printhead or it
will destroy the printhead.
CAUTION: DO NOT use Isopropyl alcohol to clean any internal parts of the printer other than the printhead.
Damage will occur.
If spotty or light printing problems persist after cleaning the thermal printhead, the entire thermal
mechanism may need to be replaced.
22
Chapter 4 Maintenance guidelines
CAUTION: Using non-recommended paper over an extended period of time can result in printhead failure.
Refer to Technical specifications on page 30 for paper specifications. HP is not responsible for printhead
failure due to non-recommended paper.

A
Troubleshooting
Diagnostics
The printer performs three primary diagnostic tests that provide useful information about the printer’s
operating status:
●
Startup diagnostics, performed during the printer’s startup cycle
●
Runtime diagnostics
●
Remote diagnostics, maintained during normal operation and reported in the print test
Startup diagnostics
When the printer receives power or performs a hardware reset, it automatically performs the startup
diagnostics (also known as level 0 diagnostics) during the startup cycle. The printer:
●
Turns off the motors
●
Performs boot CR check of the firmware ROM, test external SRAM, test EEPROM, and test main program
CRC
Failure causes startup diagnostics to stop; the printer beeps and the LED flashes a set number of times,
indicating the nature of the failure. The following table describes the specific tone and LED sequences.
LED Behavior
Failure
One blink
Boot CRC error
Two blinks
RAM failure
Three blinks
EEPROM failure
Four blinks
Memory initialization failure
To resolve:
●
Check if paper is present
●
Return the knife to the home position; failure causes a fault condition
●
Check if the rear cover is closed; failure does not interrupt the startup cycle
When the startup diagnostics are complete, the printer makes a two-tone beep (low then high frequency),
the paper feed button is enabled, and the printer is ready for normal operation.
24
Appendix A Troubleshooting
If the printer has not been turned on before, or a new EEPROM has been installed, the default values for the
printer functions will be loaded into the EEPROM during startup.
Runtime diagnostics
Runtime diagnostics (sometimes called level 2 diagnostics) run during normal printer operation. When the
following conditions occur, the printer automatically turns off the appropriate motors and disables printing
to prevent damage to the printer.
●
Paper out
●
Rear cover open
●
Knife unable to home
●
Printhead too hot
●
Voltages out of range
The LED on the operator panel will signal when these conditions occur as well as indicate printer state or
mode.

Remote diagnostics
Remote diagnostics (sometimes called level 3 diagnostics) keep track of the following tallies and prints them
on the receipt during the print test. These tallies can be used to determine the printer’s state of health.
●
Model number
●
Serial number
●
CRC number
●
Number of lines printed
●
Number of knife cuts
●
