Overview

If you are having problems establishing a wireless connection to an Access Point, check what radio channels are being used. QL printers are normally shipped with channels 1 to 11 enabled. However, for full European compliance two extra channels are required - channels 12 13. To enable international mode, use the send option in Label Vista to send a file with the following command to the printer:

Procedure

QL Printer with 802.11b wireless option cannot connect to an Access Point using channels 12 and 13.

Problems establishing wireless connection to an Access Point

 To enable international mode, use the send option in Label Vista to send a file with the following command to the printer:

! U1 setvar "wlan.international_mode" "on"
An example channel mask is illustrated below:

! U1 setvar "wlan.channel_mask" "1FFF"

The channel mask command has been "added' to the 'G' radio, and International mode is currently not supported. On the Symbol, Cisco, and Zebra 'B' radios"  International Mode and the Channel Mask feature are two separate entities. On the Symbol card if you enable International mode by sending the command ! U1 setvar "wlan.international_mode" "on" the AP takes over and determines the channel and power settings. On both the Symbol and 'G' radio with International mode off you can enable all or some channels including 12-14 using the ! U1 setvar "wlan.channel_mask" command. The Cisco and Zebra 'B' radios"only support International Mode, not the mask command.

                           International Mode      Channel Mask
 
Symbol 802.11b        Yes                             Yes
 
Cisco 802.11b           Yes                             No
 
Zebra 802.11b           Yes                             No
 
Zebra 802.11g           No                              Yes  

If your QL printer has a Cisco wireless card installed, you WILL NOT see the 'International Mode' parameter listed in the configuration label and channel masking is not supported. However, you can verify this setting by sending the following commands to the printer: 

! 0 200 200 150 1
CENTER
T 5 0 10 10 !<wlan.international_mode
PRINT

(the data will be printed on a label)
