The access point’s event log should also contain information
regarding the printer’s successful connection.
CONFIGURING FOR WPA EAP-FAST AUTHENTICATION
Next, we will modify the access point settings and the Zebra
mobile printer configuration to use WPA EAP-FAST. WPA in-
creases security further by using TKIP (Temporal Key Integrity
Protocol) as an encryption scheme instead of WEP.
You must ensure compatibility of your printer with the WPA
EAP-FAST protocol. At the time of writing the following mobile
printer models and radio options will support WPA EAP-FAST:
Radio Option
Model 802.11b CF
802.11b
PCMCIA
Zebra
802.11b
QL 220
yes no yes
QL 220 Plus
QL 320 yes yes yes
QL 320 Plus yes no yes
QL 420 yes yes yes
QL 420 Plus yes no yes
RW 220 yes no yes
RW 420 yes no yes
All the access point settings are the same as described previ-
ously for standard EAP-FAST except for the changes below:
• Set the access point to use a cipher as the encryption
mode, and select TKIP as the cipher type.
• Configure the Authenticated Key Mangement to be manda
-
tory using WPA.
• The WPA Pre-shared key should be set to ASCII.
To configure the Zebra mobile printer for WPA EAP-FAST
authentication type the following command strings and termi
-
nate them with carriage returns. The fields in blue italics will be
unique to your network and printer.
NOTE: If you previously configured your printer for standard
EAP-FAST, only the lines in red need to be typed in:
! U1 setvar “wlan.essid” “MyESSID”
! U1 setvar “wlan.wpa.authentication” “fast”
! U1 setvar “wlan.8021x.eap.username” “MyUsername”
! U1 setvar “wlan.8021x.eap.password”
“MyPassword”
! U1 setvar “wlan.8021x.eap.privkey_password” “MyCertPassword”
Or if your PAC file is not password protected:
! U1 setvar “wlan.8021x.eap.privkey_password” “”
! U1 setvar “wlan.wpa.enable” “on”
At this point you are done with the configuration of the printer.
Turn the printer off and then back on to initialize all the settings
for the radio. If your printer has an LCD display you should see
the “Security connection successful.” message for a couple of
seconds prior to the regular menu appearing.
