System Planning
This section provides you information for system planning.
2.1 Control Method
Use a driver, ESC/POS commands, or Epson ePOS SDK to control the printer.
2.1.1 Selecting a Driver
Choose one of the drivers listed in "Printer Drivers" (page 2-2), depending on the application operating
environment.
For information about the driver operating environment, see the installation manual for each driver.
2.1.2 ESC/POS Commands
ESC/POS is the Epson original printer command system. With ESC/POS commands, you can directly
control all the TM printer functions, but detailed knowledge of printer specifications or combination of
commands is required.
For information about ESC/POS commands, see the product specification. You need a non-disclosure
agreement with Epson to get the product specification. Contact the dealer for more details.
2.1.3 Epson ePOS SDK
The Epson ePOS SDK is an SDK for developing iOS, Android and Windows applications, and Web
applications. You can use the Epson ePOS SDK to control the printer with simple code.
Additionally, you can control customer displays, bar code scanners and other POS peripherals connected
to this product, and TM printers connected to the network.
The following packages are provided.
❏ Epson ePOS SDK for iOS
❏ Epson ePOS SDK for Android
❏ Epson ePOS SDK for Universal Windows apps
❏ Epson ePOS SDK for JavaScript

2.2.2 Printer Drivers
Software Manual
EPSON Advanced Printer Driver (APD):
In addition to ordinary Windows driver functions, this driver has
controls specific to POS, such as controls for paper cut, a cash drawer,
or customer display. The Status API (Epson original DLL) that monitors
printer status and sends ESC/POS commands is also attached to this
driver.
OPOS ADK:
This OCX driver can control POS peripherals using OLE technology
Because controlling POS peripherals with original commands is not
required on the application side, efficient system development is
possible.
EPSON TM Virtual Port Driver:
This driver is a Serial-USB and Parallel-USB conversion driver to make an
EPSON TM/BA/EU printer connected via USB accessible from a POS
application through virtual COM ports and a virtual LPT port. Without
making changes in the POS application that controls devices
connected through serial or parallel interfaces, devices connected via
USB can be directly controlled with ESC/POS commands.

CAUTION:
Be sure not to touch the manual cutter. Otherwise your finger might be injured.
1. Turn the power off.
2. Open the roll paper cover by using the tab, as shown in the below illustration.
3. Remove the jammed paper.
Note:
When you turn the power off by mistake during the printing operation, the cutter blade may stop in the paper
feed line. So the paper may not be fed in the first operation normally when you turn the power on. If the
phenomenon happens again after removing the jammed paper, try the solution "Autocutter Jam" (page 4-4).
Troubleshooting 4-3
4.3 Autocutter Jam
Cutter cover
Autocutter unit
Lever
Hole
Knob
If a foreign object such as a push pin or paper clip drops in the autocutter and causes the auto cutter to lock
up, the printer enters an error state and begins the recovery operation automatically.
If the problem is not serious, the autocutter returns to its normal position without any intervention by the
user.
If the autocutter does not return to its normal position by itself, follow the steps below to fix the problem:
1. Open the roll paper cover, and remove the jammed object if there is one.
2. Turn off the printer, and close the roll paper cover, and turn it back on. Then the cutter blade returns
to the normal position. If you would like not to turn off the printer, send an error recovery command
and initialize printer command instead.
3. If the cutter blade doesn’t return to the normal position, return the cutter blade to the normal position
by rotating the autocutter knob in the direction of the arrow. When it is returned to the normal
position, a lever comes into the center of hole in the autocutter frame.
4-4 Troubleshooting

Error status Various error information (Off-line / On-line), (detail of the error; Mechanical error,
autocutter error, auto-recovery error, unrecoverable error)
Paper remaining amount status It provides status of paper remaining amount (Near-end or Paper end)
Note
Near-end status (paper remain status) is supported only by printers equipped with a near-end detector.
The near-end detector is a factory option.
This printer has an Automatic status back (ASB) function that automatically transmits changes in
printer status. It is available in any control method (APD, OPOS, ESC/POS command.)
The status format depends on each control method. Refer to each manual for detail.
The statuses are useful for the following situations.
❏ When an error status is sent to the host PC, the host PC can display an error message or solution
message for operator.
❏ When “Paper near end” or “Paper end“ status is sent to the host PC, the host PC can display a warning
message for operator to replace roll paper.
5.1.1 Printer Status on APD
When you use APD to get printer’s status, you have to install “Status API“ and use it. Refer to “Status API
User’s Manual“ and the sample program of Status API for details.

5.1.2 OPOS
Note
This section describes the summary of status handling. Refer to “OPOS ADK Application Development
Guide General Functions” for details.
5.1.2.1 Checking the printer state
The state of the printer can be checked through properties supported by the printer. For example, if the
user wants to check if the printer cover is open, the CoverOpen property can be used.
This and many other events can also be checked by firing a StatusUpdateEvent.
StatusUpdateEvent can return information on the following items.
STATUS INFORMATION
PTR_SUE_COVER_OPEN Cover is open.
PTR_SUE_COVER_OK Cover is closed.
PTR_SUE_REC_EMPTY Receipt paper is out.
PTR_SUE_REC_NEAREMPTY Receipt paper is near the end. (The near end detector is factory option.
PTR_SUE_REC_PAPEROK Receipt paper is OK.
PTR_SUE_IDLE Printer State is idle.
When the printer does not have one, the status does not occur.)
When the FlagWhenIdle property is set to TRUE, PTR_SUE_IDLE is sent to inform the application that
the printer is idle. Other than when data is being sent, the printer is in an idle state, so if FlagWhenIdle is
TRUE, an event will be fired when printing is finished. After the event is fired, FlagWhenIdle will be set to
FALSE. By using this value, the information below can be found out.
*Finding out when multiple asynchronous print jobs have finished printing. When multiple asynchronous
print jobs have been sent to the printer, it is possible to know when they have finished printing. After
setting the AsyncMode property to TRUE and running the PrintNormal method, change the
FlagWhenIdle property to TRUE. When all data has finished printing, the printer becomes idle and a
StatusUpdateEvent is fired to the application with the value of PTR_SUE_IDLE.
Application Development Information 5-2
5.1.2.2 Printer Errors and Status
A change in printer status when asynchronous data is being sent is made available to the program by the
firing of an ErrorEvent and StatusUpdateEvent. When the printer changes status while nothing is
happening, the change is told to the program by a StatusUpdateEvent only.
As an example, assume that the printer cover becomes open. Usually, when data is not being sent to the
printer and the cover is opened, a StatusUpdateEvent is fired to the application. After the AsyncMode
property is set to TRUE and a method is used to print data, if the cover is opened while the data is being
sent, the program is notified by an ErrorEvent. ErrorEvents are fired when the error has interrupted the
data that is being sent. Only StatusUpdateEvent will fire when the error does not effect the data and the
data will continue being sent as normal.
Reasons for the ErrorEvent being fired and the corresponding error names are listed below.
ResultCode/ ResultCodeExtended Reason
OPOS_E_ILLEGAL There is an abnormality with the device. (Includes the following 1
error)
OPOS_E_EXTENDED Error determined by the device’s SO (Includes the following 4 errors)
OPOS_EPTR_COVER_OPEN Cover is open.
OPOS_EPTR_REC_EMPTY Receipt paper is empty.
OPOS_E_FAILURE Hard error (Includes the following 6 errors).
OPOS_EPTR_UNRECOVERABLE Error that cannot be recovered from.
OPOS_EPTR_CUTTER Error with the auto cutter.
OPOS_EPTR_MECHANICAL Mechanical error.
OPOS_EPTR_OVERHEAT Head overheat error.
OPOS_EX_DEVBUSY Device busy error.
OPOS_EPTR_REC_CARTRIDGE_REMOVED Receipt cartridge is removed.
OPOS_EPTR_REC_CARTRIDGE_EMPTY Receipt cartridge is empty.
OPOS_EPTR_REC_HEAD_CLEANING Receipt head starts cleaning.
After an error occurs, more detailed information about the error can be obtained from the ErrorLevel,
ErrorStation, and ErrorString properties.
5.1.2.3 ESC/POS commands
When you use ESC/POS commands to control the printer, you can get the status by using “status
command” including Auto Status Back command (ASB.) Please refer to the product specification.

5.3 NV memory
This printer has NV memory (Non-volatile). The data of NV memory remains after you turn off the
power. The NV memory is available in two ways.
1. NV Bit-image
Please refer "NV Bit-image Printing" (page 5-7) for detail of the function.
2. User NV memory
There is free area in the NV memory that the user can use. You can use this free area for notations, to
write other character information, or for many other purposes. The data remains after you turn off the
power. Use ESC/POS commands to read and write this data. The following are examples of purposes.
• Date of the printer for maintenance
• ID definition for developer or POS system
Note
When you use User NV memory area by using OPOS or APD, you have to use “Direct I/O method” or
“Control A font.” Please contact EPSON or your dealer for details.
Note the following when writing to and erasing NV memory.
❏ The following restrictions apply when performing NV memory operations (including data storage
and deletion).
• The paper FEED button must not be used to feed paper.
• The real-time command must not be executed.
• The ASB status will not be sent, even when the ASB function is set to enabled.
❏ The printer sometimes enters the Busy state while data is written to NV memory. It is important not
to send data from the host computer while the printer is in the Busy state, as it will be incapable of
processing any received data.
❏ Frequent use of the functions for defining data to and deleting data from NV memory can damage the
memory. As a rule in using the various commands, avoid writing to NV memory more than a 10 times
per day.
Application Development Information 5-6
5.4 NV Bit-image Printing
This printer has “NV Bit-image“ Function. This function provides printing bit-image (e.g. a shop logo.)
This function is available for any control method (APD, OPOS, ESC/POS command.)
EPSON provides tools, “TM-U330 Utility“ and “TMFLogo“ that enable registration of a bitmap image in
the NV memory of an EPSON TM series printer. The bitmap image in the NV memory can be printed
with the printer by using each control method.
Printable Size Printing method

5.4.2 OPOS
EPSON OPOS ADK provides a tool, “TMFLogo” that enables registration of a bitmap image in the
NVRAM of an EPSON TM series printer. The tool can be used from the device specific settings of the
SetupPOS utility. The bitmap image in the NVRAM can be printed with a printer by using the DirectIO
method. Concerning the available NVRAM size for the TM-U330, refer to the ADG for TM-U330 in the
OPOS ADK.
Note
You need to install the TM-U330 Utility to use the TMFLogo.
5-7 Application Development Information
TM-U330 Technical Reference Guide
5.4.2.1 Printing method
Print stored bitmap by DirectIO method.
• *Command : PTR_DI_PRINT_FLASH_BITMAP
The available NVRAM size for the TM-U330 is 256KB.
5.4.2.2 LetterQuality
It is possible to change the speed and quality of a bitmap by using the XXXLetterQuality property.
RecLetterQuality = TRUE ‘print Receipt’s bitmap in quality mode.
RecLetterQuality = FALSE ‘print Receipt’s bitmap in speed mode.
5.4.2.3 Setting of printing position by escape sequence
POS Printers support escape sequences that can be treated as printing data. The following commands are
the escape sequence command for setting of printing position.
Name Data Remarks
Center ESC |cA Aligns following text in the center.
Right justify ESC |rA Aligns following text at the right.
Normal ESC |N Restores printer characteristics to normal condition.
Note1: manner of ”ESC |cA” and “ESC |rA”
Characteristics are reset at the end of each print method or by a “Normal” sequence, so these escape sequences
cannot be used in the following manner.
OPOSPOSPrinter1.PrintNormal PTR_S_RECEIPT, Chr(&H1B) + ”|cA” + ”123”
OPOSPOSPrinter1.PrintNormal PTR_S_RECEIPT, “456” + Chr(13) + Chr(10)
The “123” characters will be printed in the center, but not under “456”. When using a new method to print
characters, it is necessary to add the desired escape sequence again.
Note2 : limitation of ”ESC |cA” and “ESC |rA”
*During rotated printing mode (Left90, right90), these escape sequences will not work.
*These will not work if they are not the first character of a line.
*It is not possible to use these on PrintBitmap method.
