Contents. What is AirPrint and How Does it Work? AirPrint was devised by to enable an iPhone, an iPad, an iPod Touch or a Mac (referred to as clients or clients later on) to print without having to install drivers on the client device. More and more new printers come with firmware to support AirPrint. There are two technologies central to the AirPrint facility on a printer:.
The printer must be advertised with. The printer must communicate with the client using The broadcast packets contain information about the capabilities of the printer, its identity and its location on the network. They also utilise some extensions (not necessarily fully explained in existing literature) to the existing Bonjour specification to allow iOS clients to search specifically for AirPrint capable printers and display them in a print dialogue.
IPP (version 2.0) is needed for print management. The client uses IPP to send the print job with information about what printer language it is in, whether it is to be duplexed, the number of copies, the resolution to be used for printing. The media output location on the printer etc.
Browsing an AirPrint Bonjour Broadcast Utilities which interact with avahi-daemon are in the package and mDNS and DNS-SD services can be browsed wth. The command avahi-browse -art discovered gets all broadcast print queues (and more) on a subnet.

Printing from an iPhone, an iPad, an iPod Touch or a Mac to an AirPrint enabled printer should just work. Upstream CUPS and AirPrint It didn't take long after the introduction of AirPrint for people with iOS clients to want to print to their non-AirPrint printers by having CUPS advertise queues which a client would be happy to deal with. However, upstream's position on including AirPrint support in mainline CUPS is expressed in and: Sorry, but we do not support AirPrint for shared printers served by CUPS. CUPS does not support iOS.
Jun 08, 2012 It then installs most components of the printer, but the last one and then asks for a dll from a CD called PDL_Common. I have checked the dll - it could be a random one - depend on the printer model and is common with HP drivers. The first is to download the printer driver from the HP Web site and install it. The second involves replacing the.DLL file the printer driver uses to obtain the text that is displayed on the screen. There are two ways to correct this problem. The first is to download the printer driver from the HP.
The two are not compatible, This view is expanded on with CUPS does not support everything that AirPrint needs, and many drivers do strange things (particularly on OS X) when you don't go through the local print dialog. Generally speaking you can get away with it for common office printers using US Letter and A4 paper, but that's about it. And: Printing of emails and web pages to Letter/A4 media generally works, but as soon as you go beyond that things fall apart pretty quickly. Here is a short list of what does not work when using CUPS as an AirPrint server: - Ready media (that's how you get to pick media sizes on iOS) - Many printer status keywords ('out of paper', etc.) - Proper media selection and scaling when printing photos - Proper media selection, rotation, and scaling when printing PDFs - Duplex printing with some drivers - Color/grayscale mode - Copies (yes, really!) Some of these deficiencies would require major changes to CUPS and its driver architecture to fix, others require driver and (in some cases) printer firmware updates to correct. Debian CUPS and AirPrint There are many users who wish to print from an iOS client to an incompatible printer.
With the idea of emulating an AirPrint printer the necessary conditions for success are:. The printer must be used with a print queue which is advertised using Bonjour broadcasting. Communication between print queue and iOS client must be via IPP. The first condition is met by setting up a print queue for the printer. Bonjour broadcasting is automatically done when avahi-daemon is installed. Fulfilling the second condition requires avahi-daemon to broadcast a DNS-SD of ipp.tcp or ipps.tcp.
In principle there is no great problem in meeting the advertising and communication conditions. The problem arises in deciding what to put in a TXT Record to ensure a client recognises the broadcasts as coming from an AirPrint print queue and successfully prints to it. In a process which to some extent involved trial and error the Debian printing system has been patched and enhanced as follows:. Generate a TXT Record for a print queue with a URF key containing DM3. Add image/urf to a pdl key. Produce a Bonjour record automatically without the need of a.service file in /etc/avahi/services. Have CUPS recognise and convert a file of MIME type image/urf.
Introduce a filter into cups-filters to convert image/urf to PDF (urftopdf). The urftopdf filter is provided because it is has become unclear whether all applications on present day iOS clients do indeed send application/pdf when the print queue supports it. Printing from an iPhone, an iPad, an iPod Touch or a Mac to any correctly set up Debian print queue should just work.
Caveat The way iOS clients handle AirPrint printing is determined by Apple and is likely to evolve over time. Future changes to iOS might impact on the ability of avahi-daemon and CUPS to service printing requests from a client.
