Zebra QL420 Printer using PEAP (Verisign Certs)

Unanswered Question
Sep 29th, 2009

Hi,

Has anybody been able to successfully get a Zebra printer QL420 Plus connected to Cisco LWAPP/CAPWAP APs ?

We are using WPA2 - PEAP with Verisign Signed Server Certificate.

I have this problem too.

Hi ,

   we have connected Zebra printer QL420 Plus to Cisco 1242 LWAPP & & 1141

   We are using WPA2 - AES - LEAP (to avoid Certificate)

   Strange thing , when you ping the device , one reply is 3ms the next 2040ms!!!

   Probably the encryption is overburden

   We are upgrading on 22/3 to firmware Z71, hope this sovles the issue

Yes I have the QL420 + printers working with 5508 WLC and 3502E CAPWAP APs and PEAP

Fotis - You will most likely find the reason for the slow ping resonce is down to the setting for "Power Mode". You likely have it set to "best". This setting controls how long the device "sleeps" before it awakens and downloads queued traffic from and AP. Setting it to "off" will put the device in to CAM (Constantly Awake Mode). This means that the device never switches its radio card off and never allows traffic to be queued on an AP. However this will mean that the drain on the devices battery will be much greater, I believe there is a slidding scale of settings for this device that go in order of highest battery drain as follows:

Best

1

2

3

4

off

Off will give you the best performance with maximum battery drain. play with the settings and see which gives best performance/batery drain balance.

Ok we will test it tomorrow

  Update 24/3/2012

 

We followed you suggestion,

most of the problems are solved, QL Printers are behaving like it should!!

Since we do not care so much about battery life we have set it to off

Many thanks for the help
