Enabling Apple® AirPrint™ with Your ® Xerox ConnectKey™ Device 1
Background ® Apple AirPrint™ is a printing technology introduced with iOS version 4.2 in November of 2010. It enables ® ® ® ® ® Apple iOS devices including the iPhone , iPad , iPod Touch, and even Mac OS X to print without installing additional drivers or software. AirPrint uses well-established, familiar technologies already in use today including Bonjour, IPP, PDF and JPEG. ® ® Xerox is now certified and implementing AirPrint in the latest Xerox ConnectKey™ WorkCentre and ® ColorQube devices.
Step 2: Device Information and Status Assuming that Step 1 has occurred correctly, the next step is for the iOS or OS X device to get all the relevant information about the printer. To do this and to move the eventual job data (in Step 3), AirPrint uses the IPP protocol – specifically IPP 2.0 – to manage print jobs and queues. IPP uses the HTTP protocol and can take advantage of all of HTTP’s security functions (SSL/TLS, etc.) All AirPrint devices must conform to the IPP 2.0 specification.
3. 4. The .dlm file can be submitted to the device via several methods, but upgrades must first be enabled at the device's Web User Interface (Web UI): a. On the Web UI (CWIS) navigate to Properties > General Setup > Machine Software > Upgrades. b. Make sure the Upgrades Enabled box is checked. The following two methods are available for submitting the .dlm to the system once upgrades are enabled: a. b. Via the Manual Upgrade Web UI page: i.
Frequently Asked Questions I can’t find my printer. What is the problem? AirPrint requires that devices are discoverable via the Bonjour protocol. Bonjour is mDNS based, and in some networks mDNS traffic is not allowed to be passed across subnets. In these cases, a device will only be discoverable if the iOS device and the AirPrint-capable Printer or Multifunction device are on the same subnet. Currently Apple does not allow for manual entry of IP addresses on the iOS device side to work around this issue.
About mDNS mDNS is the second piece we need to care about and provides a vital and core role to AirPrint and its operation. Again going back to our house on a street reference, typical TCP/IP traffic uses something called unicasting, which can be compared to the postal service. A letter is addressed to a specific house, and the letter is delivered just to that address.
One additional complication is that iOS devices will be connected to wireless networks, and the printers will likely be connected to a wired segment of the network. This isn’t inherently a problem since many networks in SMB and enterprises now have wireless available and AirPrint does not require wireless on both devices in any way.
