Papercut kb common ios printing questions gas pain in chest


No. PaperCut’s application is custom configured for your site based on your network, print environment and settings. Hence it’s not a generic app that’s distributed in the App Store. Specifically, it’s a Web Clip App distributed via an iOS configuration profile. You make this profile available only to users in your organization/network. Installation is actually easier than installing software from the AppStore. No iTunes account is required. Your users/students/staff simply need to type in a URL in the browser and the App will automatically install.

Asking users to manually enter/hit the install URL is one solution, however, if you have hundreds of devices and are using Apple’s profile management tools, other methods may be more convenient/appropriate. Check out the Advanced App Deployment methods outlined in Chapter 21.

• Ensure that the macOS server is on the same subnet as the iOS devices. Bonjour/mDNS, the protocol used to publish/advertise the queues, will only broadcast to the local subnet without further configuration (a “reflector”, the configuration of which is beyond the scope of the documentation).

• If the print server is connected to a wireless network, make sure the connection method is not preventing mDNS broadcasts. For example, some customers have reported success by connecting the server to a wired network rather than replying on a wireless network card in the macOS system for connectivity.

• Go into the CUPS web interface ( http://localhost:631/ on the macOS print server), then Administration → Server → Server Settings, and confirm that ‘Allow printing from the Internet’ is checked. CUPS may ask to be restarted after applying that setting.

There could be a number of reasons for this. The first step is to check that the job has arrived in the macOS system’s print queue. It should be listed under the user “guest”. The guest job needs to be authenticated. PaperCut does this by matching the job’s originating IP address with the IP address of the iPad. This is done using the PaperCut Web Clip app on the iPad. If there is a proxy server in between the iPad and the PaperCut server, this IP address matching may fail. Please see this KB article for more details: iPad Printing and Proxy Servers.

We have found that selected iPad firmware versions have problems with double sided printing (duplex) – silent failure with no print. Our analysis suggests that it’s a problem with iOS because no network traffic is sent through to the print server. The only known workaround at the current time is to print single sided. We hope Apple address this in a future iOS update.

Update: with more recent versions of iOS, we’ve found that we can change some of the behavior in the Bonjour advertisement that fixes most of these failures. If you’re finding that you’re seeing this issue in your environment, make sure that you upgrade to version 15.3 or greater – and also take a look through this overview and troubleshooting reference.

We are officially supporting devices with iOS 5, and we recommended running the latest version of iOS wherever possible. If your organization has iOS 4 devices that you do not wish to upgrade, we are not aware of any reasons they will not work, but you may encounter compatibility issues due to the older patch levels.

Are you printing double sided? Try turning double sided off. There seems to be issues with double sided printing on some iOS devices, as of iOS 5.0.1. note: this should now be fixed with PaperCut version 15.3 or later – see this KB article for more information!

Try printing with PaperCut tracking disabled (using Control Printer Monitoring.command) to help diagnose the problem. When PaperCut is disabled from the queue, “it’s one less variable”. If printing problems persist after disabling, then check the CUPS event log and/or look at the print queue/driver configuration/setup.

Yes. This is possible. Once an iPad print job has entered the PaperCut system, it’s treated like any other job. This extends to job release. An iPad printing job can be released from a release station (sitting on any operating system, including Windows), or even from an embedded application running on an MFP (if you’re running PaperCut MF).

AirPrint is a technology that exists on printers to support direct printing from an iOS device to a printer. PaperCut can’t work with this technology because it needs to intercept the print job before it reaches the printer (e.g. to stop the job if the user is out of print credit or is violating a print policy rule). For PaperCut’s iPad printing, the iPads pass the
