Here's a very simple configuration guide for CUPs and Avahi to allow iPads etc to print. I did it on a Linux system but really this will work on anything including those hacked Linksys routers.

Just when we thought it was about to be released. BOOM! Another update. It's still possible it'll be released early next week if there are no issues at all.

Maybe they found a last minute problem with Build 10H568.

Yeah, they have a small AirPrint problem:

Apples servers are going to get rammed when these all hit

No, Akamai Networks provides a worldwide infrastructure, so that the downloads can be as fast as possible. Apple distributes all software updates over the networks/servers of Akamai.
 
How do you think Airprint can print to a non wi-fi printer without anything in between to communicate with it?

ive set up my wireless printer to my macbook pro. so when i get home, and i want to print something, i just click print and itll print out for me
why cant that happen in iOS?

Currently under OS X print drivers are custom written by the manufacturer to convert the output of each program to the format needed for each model of printer. These drivers live on your MacBook.[1] Most (cheap) printera take a very limited format of input. So what happens now is that all the hard work is done on your Mac and the simplified output is sent over WiFi to your printer.

Apple wants to move the printer drivers onto the printer so they don't have to be stored on the iDevice (a mobil device would need to keep ALL the driver around because it would never know which ones it would need at the next location), and don't have to be run on the iDevice (which doesn't have a lot of RAM to load the driver and buffer the output on top of the running app).

AirPrint sends the output, using as single standard format, to the printer and expects it to do the hard work on its end. That doesn't work for most current printers so you need another computer (Mac or PC)) in the middle to translate.

Over time, more and more printers with come with software to accept the AirPrint format as direct input and therefore not require an intermediary to convert it to their custom format. HP seems to be in the lead at this for now but its reasonable to expect others to get on board the AirPrint bandwagon.

[1] In fact, most of the work is done by a standard library called CUPS with each manufacturer supplying only some specific bits of code specific to each model.

ummmmh :D did you read his statement? wireless vs. WIRED! :rolleyes:

if you don't have a wifi printer it has to use a computer to manage the jobs, if you have a wifi printer it should be good to go as it can find it over the network itself.

I don't have a wifi printer but it's connected to airport extreme which means I can print from any of my 4 macs of home regardless of where I am but if you have nothing like my setup then you just share your printer out from system prefs. which isn't a big deal since a print server doesn't take that many resources.

Well, considering that all of these practically have to hit within hours/days of one another, likely Mac OS X 10.6.5 first, and a day later, iOS 4.2 and iTunes 10.1, someone will be hammered, considering the sheer numbers of people after this - Mac users are more savvy than Windows users, so the vast majority will update to the latest and greatest within hours of release, adding a large strain for this 700MB+ file, plus the 700MB iOS 4.2 firmwares for iPad, iPod touch 4, and iPhone 4. This is a LOT of stuff. Just saying.
 
umm... Did you read the original statement? ;) ... There was discussion whether printers would work when shared through an AirPort base station or Time Capsule. Seems like that's a no-go: Printers need to either provide AirPrint themselves (through WiFi, of course) or be shared through a computer. Basically, this all means that while you now (soon) _can_ print directly from an iPad, you still probably won't want to, because wherever you've got a printer, there's a hiiiiiiiiiiiiiigh probability that you've also got access to a computer, where you have much more control over print jobs. For example what paper to use. Whether to print in colour or not. Etc.

Thanks "SBeardsl" for a clear explanation written without any nastiness to others! Great post!

Thanks for the clear explanation of AirPrint. Based on this, it sounds like Google Cloud Print (when released) will be better than AirPrint, because the print drivers will live in the cloud and will not require another computer or a special printer to print directly from your mobile device. This seems like a distinct advantage for Google's forthcoming system. Am I wrong on this? Why didn't Apple take this approach?

Simple. Apple is not a cloud advertising company that makes money by combing through your personal data to sell to advertisers. Data you naively think is private, but is actually not.

And if AirPrint was like Google's Cloud Print, you couldn't print unless you had an Internet connection.

Yep, thats exactly what it is. Just suck it up and use your gateway mac for now until new printers are released. Trust me, its going to be better than spewing your printing data all over the internet.
