AirPrint lock without the hack with urftopdf
  

So, iOS 4.2.1 is out and before has been written a lot about AirPrint how you can unlock by using three files (from one of Vorverson 10.6.5) for all printers. So far so good. But it goes much easier. And all without loading the three files.

Here for the first time the solution, what to do. For the impatient among you. Then I will give some background information about this. AirPrint to unlock a file only needs to be generated with one line of text in the directory / usr / share / cups / mime stored. In this case no system files are changed, which is ever quite positive. The line is:
  • image/urf urf (0,UNIRAST<00>)
Now in the IOS device you can select the printer in the Print dialog.

The previously known tips for AirPrint go to 10.6.5 to allow for any printer accessible from the same. It installs a printer driver (the file named 'usbtopdf') and it will be a new file type called "URF" made famous. And although in two places. Once it is saved as a file type definition itself and then this new file type associated with the printer driver.

With snow leopard 10.6.5. Funchal, is well known, so HP printer with AirPrint. In this case, these printers on the network via Bonjour will be announced. The Linux users have now discovered that it also has a new type, namely type "URF" and is, and this is the approach that the IOS device, just send PDF files to the printer and a new file format. Obviously this new file type is used only to indicate to the printing and to enable quasi possibly future functions. Whatever the case, the whole thing then led to a rethink.

If AirPrint for the file type "URF" is not used, then the printer driver is not very likely to need. If the new printer driver is not necessary, it is also the link for the file type with the driver makes no sense. And since the printing system in Mac OS X handles everything from house internally only once in PDF, so stay left only the definition of the new file type. And that's caused by this one line. It gives the new file type "URF" known.

After a reboot of Mac OS X, CUPS printing system of all files in the / usr / share / cups / mime with a file extension *. load types. And that causes snow leopard also to recognize the new URF AirPrint type and the network to announce. And so now can also use 4.2.x iOS recognize the printer and devices.

Well, that was then, the solution. Simply enter only the new file type known and install any other driver.

  • The underlying concept should work on Leopard, and also to Tiger. More specifically for each system on the "CUPS (the printing system) and Bonjour (the service that makes the printer on the network known) and would also run Linux, other Unix and Windows. However, it needs to have a few other things. I've already made, try the times on Leopard. About the result I think you, of course, up to date.
  • If the printer is connected to the Mac? Is the Mac? Have you installed the script as described, the Mac restarts, printers deleted, added together and share? In that order? Then everything should work
