Notes on Security when Using Wireless LAN
(Important information on customer rights (maintaining privacy)
The advantage of using a wireless LAN over a LAN cable is that, because information is
exchanged using radio signals, you can easily connect to the network if you are within range of
the radio signals. A disadva

implemented in some way, problems such as the following may occur.
•Communication data can be intercepted
A third party may be able t

card numbers, or they could intercept the contents of personal e-mail messages.
•Unauthorized access to the network

Overwrite the contents of intercepted data and resend it (falsification)
Introduce a computer virus which could cause data loss or system crashes (damage)
Initially, the possibility that such problems could occur through settings concerning the
security of the wireless LAN product and by using the product are decreased, because the
wireless LAN card and the access point have security measures to deal with these problems.
We recom m e nd that you use this product

printer that can print on die-cut/full-surface labels and thick paper. Its compact size allows
installation in a variety of areas. It is a model of the TM-i series.
Printing
•Printing on die-cut labels (labels pre-cut to the desired size) is possible.
•Printing on full-surface labels (labels cut to the desired size with an auto cutter) is possible.
•Printing on thick paper (up to 145µm) is possible.
•Supports a maximum paper width of 80mm, and paper widths of 38mm to 70mm when using
a roll paper spacer.
• Roll paper wit
h a maximum 90mm diameter can be used.
Handling
•Can be installed horizontally or vertically.
•Easy drop-in paper loading
•Cable connectors can be stored inside the printer.
Intelligent functions
•Supports ePOS-Print.
•Direct server printing with data sent from a web server to the printer (supported by ePOS-
Print XML)
1
•Printer driver is not required.
15
Software
•Highly versatile through the adoption of control commands that conform with ESC/POS.
•In addition to a variety of bar codes, printing 2-dimensional symbols (PDF417, MaxiCode,
QRCode) is possible.
•A maintenance counter function is supported.
Interface
•Ethernet interface, USB host with 4 ports.
Others
• Development kits such as MSDN are not required for application development.
•Registering web pages on the TM-L90-i makes them accessible on the Web.
•Methods to efficiently construct multiple systems are included. For details, see the "TM-i
series Easy Setup Guide".

Power Switch
When DIP switch 1 is OFF (power switch: enabled), the power is turned ON/OFF. Press and
hold the switch for 1 second to turn the power on, and 3 seconds to turn the power off. After
turning the power on, approximately 30 seconds is required before printing is possible.
Before turning on the printer, be sure to check that the AC adapter is connected to the
power supply.
It is recommended that a power-off processing command be sent to the printer before
turning the power off. Doing so allows the latest maintenance counter value to be saved.
(Maintenance counter values are generally saved every two minutes.)
For more information about commands, see the "ESC/POS Application Programming
Guide".

NV Memory (Non-Volatile Memory)
The printer's NV memory stores data even after the printer power is turned off. NV memory
contains the following memory areas for the user:
•NV graphics memory
• User NV memory
•Memory switches
•User-defined page
•Maintenance counter
•Paper layout settings
As a guide, NV memory rewriting should be 10 times or less a day when you program
applications.
NV Graphics Memory
Graphics, such as shop logos to be printed on receipts, can be stored.
Use the TM Flash Logo Setup Utility to register graphics.
User NV Memory
Yo u can store and read text data for multiple purposes, such as for storing a note including
customizing or maintenance information of the printer.
Memory Switches
Yo u can make a variety of printer settings, such as print density and printing speed.
For more information about memory switches, see
"Setting the Memory Switches" on page 96.
User-defined Page
Yo u can store character data in the user-defined page (character code table: page 255) so that you
can also print characters not resident in the printer.

Chapter 1 Product Overview
Maintenance Counter
With this function, printer information, such as the number of line feeds, the number of autocuts,
and printer operation time after the printer starts working, is automatically stored in NV
memory. Refer to the counter information when performing regular maintenance and replacing

Paper layout settings
Paper layouts can be registered in this printer.
Registration is performed through panel operations or by executing commands.
If a paper layout is not registered, the printer will automatically determine the layout. The
results of this determination are temporarily saved in the printer. Whenever the printer is
turned on or the roll paper cover is closed, the paper is fed and the printer automatically
determines the paper layout.
(See "Auto paper determination" on page 95.)
