Identify Printer Capability 
What is it? 
The Xerox® ConnectKey® enabled device can be identified from remote IPP clients trying 
to find the device by either making a sound or a message at the Xerox Device Local 
Interface. This could be used to help find a particular Xerox® device if a client is in an 
area where multiple devices are supported. 
Requirements 
The fault tone is enabled. 
Limitations 
This Identify Printer Capability is not yet supported on AirPrint™ clients. 
Configuration 
1. By default, the IPP identify printer functionality is enabled.  
2. To configure the IPP identify printer functionality:  
a. In the Xerox Device Web page, click Properties > Connectivity > Setup.  
b. For Protocol, next to IPP, click Edit. IPP should be enabled by default. 
c. To configure the IPP identify printer functionality, for Identify Printer, select an 
option.  
 On: This option enables an IPP client to request the printer to identify itself 
through a graphic or sound.  
 Off: This option revokes the ability of an IPP client to request the printer to 
identify itself through a graphic or sound.  
 
  
Note: When the IPP client requests sound, the Identify Printer feature uses the 
Fault tone. You can configure the Fault tone on the printer control panel. For 
details, see the System Administrator Guide for your printer model. 
d. Click Save.

Workflow 
 An AirPrint™ client (such as a future iOS device) user is attempting to submit an 
AirPrint job to a local Xerox® device. The user has selected a Printer, but isn’t sure 
which of the several output devices is actually the printer they have chosen.  
 The AirPrint user submits an Identify Printer request to the Xerox® device. 
 The Xerox® device sounds the fault tone and/or raises a Local UI message or flash to 
allow that user to identify the Xerox® device.  
Secure AirPrint 
What is it? 
Secure AirPrint is AirPrint communication over IPPS (secure IPP) via HTTPS. By default, 
the ConnectKey® enabled device can support both non-secured AirPrint (over IPP) and 
Secure AirPrint (over IPPS). The ConnectKey enabled device can be configured to only 
support Secure AirPrint by enabling the HTTP configuration item called “Force Traffic 
over Secure Connection (HTTPS)”. 
Requirements 
When “Force Traffic over Secure Connection (HTTPS)” is enabled, the Xerox® device will 
support AirPrint only over IPPS (only Secure AirPrint). 
When “Force Traffic over Secure Connection (HTTPS)” is disabled, the Xerox® device will 
support AirPrint over either IPP (AirPrint) or IPPS (Secure AirPrint). 
Limitations 
Enabling “Force Traffic over Secure Connection (HTTPS)” switches all HTTP requests to 
the Xerox® device to HTTPS, not just those related to AirPrint.

Troubleshooting 
What if I can’t find an AirPrint™ printer from my Apple® device? 
I can’t find my Xerox® device when I try to print from my Apple device or I get a message: 
No AirPrint Printers Found. What’s going on? 
 First try to confirm that AirPrint is enabled on the Xerox® printer. See “How is 
AirPrint™ enabled and configured on the Xerox® device?” above. 
 Next, AirPrint requires that devices are discoverable via the Apple proprietary 
protocol. In some networks, this traffic is not allowed to be passed across subnets. In 
this case, a device will only be discoverable if the Apple device and the Xerox® 
device are on the same subnet. 
– Make sure that your Apple device is connected to the same subnet as the 
Xerox® device. 
a) From the Apple device, tap on the Settings icon. 
b) Navigate and tap on Wi-Fi networks.  
c) Confirm the Apple device is connected to the correct Wi-Fi network (check 
mark next to network name). 
  
Check the IP address of the Apple device by selecting the More Details 
arrow to the right of the network. 
  
d) Confirm that the IP address of the Apple device is for the correct network.

– Make sure that the Xerox® device is connected to the correct network. 
e) Either print a Configuration Report to confirm the IPv4 address of the device 
(See the Connectivity Physical Connections, and Connectivity Protocols, 
TCP/IPv4 sections of the report) or check the Xerox® device’s Control Panel 
and select the Machine Information button and view the IPv4 address in the 
Machine Information tab. 
f) Confirm that the IP address of the Xerox® device is for the correct network. 
 If both devices are on the same subnet and your device is still not being discovered, 
check with your IT administrator to ensure that mDNS traffic is not being filtered on 
your network.  
 Finally, if you still can’t find the Xerox® AirPrint™-enabled device, restart the Apple® 
device and the Xerox® device. 
Where are my AirPrint jobs on the Xerox® device’s queue? 
When an Apple iOS device appears to submit consecutive print jobs to an AirPrint-
enabled Xerox® device, it really only sends the first job and queues the subsequent jobs 
at the Apple device until it gets notification that the prior print job is complete. After one 
job completes, the next job is released from the Apple device. This behavior is driven by 
Apple’s AirPrint implementation. 
For example:  
 On an Apple iOS device, submit five consecutive jobs to a Xerox® device.  
(See How do I send a job over AirPrint™ from an Apple® iPad®? or  
How do I send a job over AirPrint™ from an Apple® iPhone®?) 
 Observe the jobs in the Apple device’s print queue. (See How do I manage/cancel 
print jobs from my Apple® device?) 
  
 
   
						

							 
Using Apple® AirPrint™ with Xerox® ConnectKey® Technology Enabled Devices User Guide  23 
 Notice the status of each of the five jobs by touching each job in the list. The first job 
has a status of Printing, all subsequent jobs are Waiting. 
    
  
On the Xerox® device, select the Job Status button. Observe the device Print 
Queue (Active Jobs) and notice that only the first job from that Apple® iOS device is 
visible. It is the only job that has been sent to the Xerox® device from that Apple iOS 
device. Once this job completes, the next job queued on the Apple iOS device will 
be sent to the Xerox® device. 
  
I discovered the Xerox® device from my Apple device. Why am I having trouble 
with my job completing? 
Please try disconnecting your Apple device from any cellular data networks (by enabling 
airplane mode and re-enabling W i-Fi) and then try submitting the job again.

I submitted a print job from my Apple® device to a Xerox® device via AirPrint™, but 
I am getting a message on my Apple device that says “Check the printer for 
errors.” What is going on?  
AirPrint provides generic error message handling. The AirPrint message, “Check the 
printer for errors,” can correspond to multiple kinds of alerts or faults on the device and 
often it will not impact the ability of the Xerox® device to print. Select Continue and check 
the printer for your output. If your job has not been completed, check the Xerox® device 
for errors.  
 
I submitted a print job from my Apple device to a Xerox® device via AirPrint, but I 
am getting a message on my Apple device that says “Printer out of paper.” My job 
still prints. Why is this happening?  
AirPrint provides generic error message handling. The AirPrint message, “Printer out of 
paper,” can correspond to multiple kinds of paper alerts on the device and often it will not 
impact the ability of the Xerox® device to print. The message may be alerting you that 
one tray is out of paper but other trays may be available to complete the job. Select 
Continue/Cancel and check the printer for your output. If your job has not been 
completed, check the Xerox® device for errors. 
I only see a few printer configuration features in the AirPrint dialog. Why? 
Currently Apple is only providing a limited subset of printer configuration features from 
within iOS. As the AirPrint feature evolves, you can expect to see additional device 
settings and capabilities within the print dialogs. For the time being, only a small number 
of printer configurations are available.  
 
What are some possible solutions for Enterprise Networks that span multiple 
subnets but still want to leverage AirPrint capabilities?  
Please refer to: “AirPrint in multi-subnet networks – Xerox® ConnectKey® Enabled 
Devices Deliver Apple® AirPrint™ to the Enterprise”.
