Zebra MtP400 Operator's Manual - Wi-Fi

Interfacing to a Host Computer 

When discovered, the default name that will appear will be “MtP400-xxxx” where “xxxx” is the last four digits 

of the Bluetooth interface’s hardware Address.  To obtain the printer’s Bluetooth name, you may use the 

printer’s Setup menus or you may have the printer print it out.  To print all the configuration for the interface, 

press and hold the   Enter Button until “Printing Setup” is displayed. 

Whenever a host device has established a connection to the printer, the 

 Wireless Indicator will be lit.  When 

the host closes the connection, the indicator will turn off.  To conserve battery power, application programs 

should disconnect from the printer whenever possible. 

Wi-Fi

®

 Interface 

In addition to the standard RS-232C Serial interface, your MtP400 may be equipped with an optional Wi-Fi 

interface.  Wi-Fi interfaces are built into some PDA’s and may be added to most others.  Wi-Fi interfaces may 

also be added to notebook or desktop computers and as an “access point” to a wired network.  To communicate 

using the Wi-Fi interface, “Wi-Fi” must be selected in the Interface Menu as described on page 26. 

The Wi-Fi interface uses wireless, radio frequency signals to communicate, which eliminates the line-of-sight 

requirement imposed by the optional IrDA interface. 

The MtP400 Wi-Fi interface acts as a server and will accept connections from a host device such as a PDA, 

notebook computer, or a network server. 

The MtP400 Wi-Fi interface conforms to the IEEE 802.11b standard.  The factory default settings for this 

interface are: 

 WLAN 

Type: 

Infrastructure 

 WLAN 

SSID: 

any 

WLAN WEP Bits:  0 (Off) 

 WLAN 

Auth: 

Auto 

IP Address Assign:  DHCP 

 Port: 

8023 

These settings for the Wi-Fi interface features may be modified using the Interface Setup Menu as described 

beginning on page 26 with the exclusion of the IP Port.  Note that changing the values of some of these features 

may cause additional features to be displayed.  For instance, changing WLAN WEP Bits from “0”, or Off, to 

“64” or “128” will cause the “WEP Key” feature to be displayed so that the appropriate sized encryption key 

may be entered. 

To print out the current Wi-Fi configuration details, you may press and hold   Enter Button until “Printing 

Setup” is displayed.  This feature is especially useful for obtaining the current IP address when assigning 

addresses via DHCP.  When doing so, be sure to wait several seconds after turning the printer on to allow it to 

establish a connection with the network and be served an address. 

The 

 Wireless Indicator will light whenever the printer is currently receiving a print job. 

When operating in Infrastructure mode, the printer will attempt to conserve battery power whenever possible by 

placing the Wi-Fi interface into a low power mode when not communicating.  However, according to the IEEE 

802.11b standard, the printer must be granted “permission” from the network’s Access Point before operating in 

the low power mode.  Since different Access Point manufacturers implement this feature differently, the amount 

of power saving actually achieved varies.  The actual power saving also varies with the amount of network 

traffic.
