URF is obligatory. PDF is the PDL of choice if the device supports it. So, you do not *have* to send PDF to Airprint but is very common for that to happen.

The file type sent by Safari (say) from an iOS device is controlled by
Apple. Observation shows it is PDF.

I've said specifically it has a PDF converter. It must have; the printer
does not understand PDF.

That last line is not correct for using Debian CUPS with an iOS device.
The process is:
iOS device -> CUPS (BUL out) -> Printer -> Print
With CUPS the process is:
This is done by CUPS
+------------------------------------------------+
| Input file -> convert to PDF -> Convert to BUL | -> Printer does something
+------------------------------------------------+
Because the sending device is driverless all I am saying (I have no
special insight) is that with Airprint we have:
Done on the printer
+------------------------------------------+
iOS device -> Sends PDF -> | Convert to BUL -> Printer does something |
+------------------------------------------+
One filtering stage has to be moved to the printer. I do not know how it
is done but it reasonable to guess the same method which CUPS uses is
also used. What I am sure about is that there is no PDF interpreter on
the printer. Brother already have the technology to convert from PDF to
BUL and, as a practical point, an interpreter would raise the cost of
production of the printer.
Substitute PS, PCL, QPDL etc for BUL to see how other manufacturers
might deal with AirPrint.

The part played by what is in the Bonjour broadcasts is crucial to the
whole thing working. Apart from the questionable use of cp, IPP is used
for printing and is what is advertised in the broadcasts.
The CUPS backend converts PDF to BUL. But, as it happens, you do not
need cupsd to print to an AirPrint printer.

Once again, I don't understand this statement because I don't understand your terminology... My question with pronouns removed: "So if a PDF arrives by AirPrint, how does the MFC-J5720DW printer interpret the PDF if the MFC-J5720DW printer doesn't have a PDF converter?" Your response AIUI with pronouns removed: "I've said specifically the MFC-J5720DW printer has a PDF converter. The MFC-J5720DW printer must have; the MFC-J5720DW printer does not understand PDF." Is that what you mean to say? If not, couuld you replace the appropriate nouns by different nouns. > > I'm used to this: > > > > Paper -> scanner -> PDF containing image -> [...wifi...] -> computer > > > > where the PDF is really just a container with an image in it. > > And then its converse (but not its inverse): > > > > Computer PDF -> CUPS -[convert]-> BUL -> [...wifi...] -> BrotherPrinter -[RIP]-> paper > > > > where the Computer PDF contains some postscript-like code mixed > > in with fonts etc which has to be "converted". > > > > So now with AirPrint we have: > > > > Phone PDF -[no-driver]-> [...wifi...] -> AirPrint -[convert]-> BUL -[RIP]-> paper > > > > Linux computer PDF -> CUPS -> [...wifi...] -> AirPrint -[convert]-> BUL -[RIP]-> paper > > That last line is not correct for using Debian CUPS with an iOS device.

None of your examples (the bits -> like -> this) have "AirPrint" mentioned in them. I'm trying to learn from you what AirPrint is and what it does. And yet your statements about it say things like "The AirPrint facility handles a PDF (it has to)." and "Substitute PS, PCL, QPDL etc for BUL to see how other manufacturers might deal with AirPrint." which tell me nothing specifically about AirPrint. > > but what does the backend of CUPS have to do?

I can see that CUPS has some work to do to find the printer with whatever it uses (dnssd/avahi/bonjour/...). That part doesn't really interest me in this discussion. > The CUPS backend converts PDF to BUL. Why bother? The AirPrint technology built into the MFC-J5720DW printer can do that. Why can't CUPS send PDF down the wire to the printer, thereby avoiding all the driver-crap? You've just said "The AirPrint facility handles a PDF" (requoted above). Why not let it do so? > But, as it happens, you do not > need cupsd to print to an AirPrint printer. OK. What's the minimum that you _do_ need? By minimum, I'm meaning things like drivers; the things that linux users get tripped up by; the things that make "perfectly functional" printers into doorstops. Cheers, David.

Why not let it do so? my guess is that airprint is a black box between the "air" (what ever it means) and the printer, like an ethernet card can be. If you send ethernet signal through usb, the printer wont understand it. If it's so, the printer only understand pdf if used with airprint. the other solution is having in the printer a linux box (invisible to user) having an airprint interface, an usb interface, etc, and then the usb may also understand pdf. jdd

Not having such a printer, I can only quote what I see written by people who should know: "AirPrint is built into most popular printer models, like the ones listed in this article." which includes MFC-J5720DW in the list. "On your Mac, you can also connect your AirPrint printer to a USB port or Ethernet port if you don't want to print wirelessly. Check the documentation that came with your printer to see if it includes one of these ports."

AirPrint uses open standard protocols to operate. A large, influential international company has all its printers at head office AirPrint enabled, You visit there with a proposal for a 10M Euro contract. You are asked to print the contract. Your laptop runs Debian and can pick up the Bonjour broadcasts of a printer. You print and an hour later the contract is signed. I do not know what your point is.

Writing "why not" implies disapproval. I'm not sure if you meant that. Much of this long thread is about trying to find out if there's a way of getting AirPrint to facilitate sending raw PDF files from non-iOS devices (like linux PCs) to a printer that otherwise might not accept this format. If they've followed the thread this far, they're unlikely to reject it just because Apple were behind it. Cheers, David.

OK, the fact that you only addressed that part of my posting means that I'll stop here. None of your earlier suggestions has seemed sensible to me or advanced my understanding of AirPrint. (Notice "me": I'm not claiming to know what others think.) You write "Is Airprint free?". Is this a real question or a pointed remark designed to create more discussion? I can't tell. Why don't you just look it up? You write "not from me, but from others, may be." Perhaps you might google the following phrase. That's what I think. "creating an impression that a specific and/or meaningful statement has been made, when only a vague or ambiguous claim has been communicated" Cheers, David.

I got the impression than you don't want to use the brother driver because it's not free. If it's not that, I'm sorry. if It's that, I think that a driver is just an extension of the hardware, so why use a non free hardware an don't use the same non free driver. this don't mean working on a free solution is not interesting, but replacing a non free solution by a non free other solution is not very funny. We all work constantly with non free solutions, including RMS, whatever he says... the more the better, but where to stop? jdd https://libreboot.org/ http://www.openfirmware.info/Welcome_to_OpenBIOS (and so on...)

This sort of breaks down when you realise that drivers are actually software to be used with hardware. They are only 'extensions of hardware' in the sense that hardware requires drivers to work, and so certain drivers must be used with certain hardware. There is no such thing as 'non-free hardware'- just hardware for which there are no free drivers available. That situation can be remedied by the development or release of free drivers and firmware. > We all work constantly with non free solutions, including RMS, > whatever he says... the more the better, but where to stop? Indeed. Until recently Stallman himself used a computer with non-free BIOS, until his fling with MIPS and now LibreBoot.

You've just said "The AirPrint > facility handles a PDF" (requoted above). Why not let it do so? Why not, indeed? The Bonjour broadcasts of the printer should be picked up by avahi-daemon and the printer listed in the print dialogues of some applications (e.g Iceweasel/Firefox). These applications produce PDFs as a matter of course. They are sent directly to the printer and the printer sorts them in some way. No filtering on the machine is necessary so cupsd is not involved, whether or not it is on the system. This implementation of this idea was the objective being worked towards in https://lists.debian.org/debian-user/2016/03/msg00401.html as a solution to Jarle Aase's issue. All we need is someone with an AirPrint printer to test it. :). But if the printer is not AirPrint-compatible we will need cupsd and the backend filter.

When cupsd isn't running no drivers are needed because the print job is sent directly to the AirPrint-compatible printer. avahi-daemon is required, of course. When sent to a non-compatible printer the minimum number of drivers needed is determined by the printer make and model when it is set up as a local or remote shared printer with CUPS.

It's of the greatest consequence if there's a way of getting a linux box to send PDF files to an AirPrint printer and have them print. It means you can walk into a store and just buy something, take it home and it works. A bit like when I worked in a university: the printers understood PDF files so I knew I could just send stuff to the queue and it would print it. Here's my old methodology for buying a printer: -Go to the store and look and printers. -Persuade wife to "check reviews" rather than buy straight away. -Go home and look at linuxprinting-type websites for linux compatibility. -Search forums for complaints/difficulties. -List some linux-compatible models. -Go back to store only to find that all these model numbers are out of date and unavailable, replaced by shiny new models. -Persuade wife that the shiniest model she wants is going to be a great doorstop (or else she's going to have to print all my wants from a stick). -Buy a printer. -Find a driver that kind-of works. -Work round the problems that the driver throws up. > > > The part played by what is in the Bonjour broadcasts is crucial to the > > > whole thing working.

I thought we had established that the filtering process takes place
entirely on the printer. After all, there are no drivers on the sending
device.

Ok, yes. But I have said what I mean by an interpreter. You haven't.

CUPS is not involved in printing to an AirPrint printer. Debian CUPS has
been patched to enable an iOS device to send to any printer (AirPrint
capable or not). The principles to do it have been worked out and it is
Bonjour broadcasting which is the key.

Since it is mentioned twice, your major tussle with printer purchase
appears to be with your wife. Driver choice and adaptation pales into
insignificance compared with this, :)

Unless the printer has a PDF interpreter you will be disappointed with
the result.

Gene Haskett has an HL-3170CDW, which he now knows does AirPrint. I
believe he is someone who is up for a challenge. Compared with flooded
basements, lightning strikes, falling trees and power cuts this is small
beer. If he is amenable he could
1. Install avahi-daemon and avahi-utils.
2. Do
avahi-browse -art > discovered
and post the file "discovered" here. Then we might progress.
Your printer cannot deal with files sent directly from an iOS device.
Through the mediation of Debian CUPS it can.

But in order to do it, he would have to install Jessie, would he not? And I don't think he has a spare computer on which to do so. :-( Lisi
