Which is the best wireless printer for mac products (macs, iPads , phones and laptops)?

Best is pretty subjective, but there are lots and lots to choose from.

If you need AirPrint capability, you need to choose one of these - http://support.apple.com/kb/ht4356

If you do not care about AirPrint, most any printer can work. If you buy a wifi printer, then you don't even need to set up printer sharing. I have an older HP 6988 (or 6899, something like that anyway) and a Kodak 7200-something printer/scanner - both are wifi (no cabled connections to anything) and I print and scan with them from my MBP just fine. I have printmagic and a couple of other apps on my iPhone and iPad and print from those using one of those apps.

Major brands are all pretty good. Some are more apple-friendly. Your should read reviews in Macworld, MacUser, and PC World if you really want to research it. Canon, Epson, HP are all good brands -- some people complain about HP putting files and software all over their Macs and inserting startup processes.

After you finish with reading reviews, I'd list the features you want and select by that. Like you might want wireless, scanning, copying etc. Different printers have different features. For instance, some have feeders to, say, scan or copy 50 sheets in rapid sequence, while others you have to lift the cover for each sheet, one at a time. Others have easy to use duplex (2-sided) copying and printing. The Canon 8120 unit I use has very easy to use buttons on the unit. You can scan and send the pdf or jpg right to any computer on the network by pushing one of those buttons. Copying is another one button operation. The reviews (including those by Consumer Reports) list how much the cost per page is -- this is what your long term cost will be determined by, not the cost of buying the printer. Also, check the reviews for quality of photos and/or printed text, depending on what you will use it for.

I just purchase a Canon MG5320 all in one printer, and I can not get my IMAC to recognize the printer. I gave up trying to do wireless and now I connected a usb cable to the printer and pluged in to the computer, but nothing happens. I have an IMAC OSX 10.6.8 (10K549)

Thanks

Hands down the Epson 845 Wireless Printer! It seriously does it all. It plays nice with all my apple products and was a so easy to set up. For the money, I think it's the best value you're going to find. Just read the reviews:

A large amount of the replies to this link actually said not to buy it. I have an Epson S401 and I'm about to send it to the scrap yard. Epson is absolutely horrible in regards to the drivers required to install. Once it's installed, getting to some of the menu's to change the "default" options are painful. It shouldn't be that hard.

I'm probably going to chance the Canon mentioned in Mac iLife http://www.maclife.com/article/features/ultimate_wifi_printer_shootout

I have just bought a Canon Pixma MG 6350 for £109 free delivery. It scans, copies, prints, prints CDs and lots of other useful items. I can airprint from my Macbook, i phone and i pad and I also have a windows desk top connected via a USB port. Setting up was relatively simple with not too many frustrations and I'm no boffin. I am pleased with print quality and the printer is very neat, roughly 500 x 370 x 150. It is available in shiny black or white. I like to make CDs, DVDs of family movies etc and like to use imprintable CDs for this, the only thing I would have liked, which it does not do, is be able to add text and my own titles. Printing to disc is via a memory stick for photos or directly copying from an original disc.

The Epson Workforce WF-2540 Wireless Printer supports airprint, cloud print and every apple product out there.

I have found Brother's printers work great with my Macbook, iPad, and iPhone.

Everyone's answer is a good one and I'm not sure that there is a "Perfect" printer. Just listen to the comments and do your research. Before you purchase check into cost of ownership. Most all printers are sold cheap and then the manufacturer kicks you in the pants with the cost of toner and ink cartridges. Another trick they play, especially laser printer mfgrs. some manufacturers only put a 1/4 charged toner in the box, thus making you have to buy toner earlier than normal. At any rate over the life of the printer it is not unusual to spend 10 times the printer costs, maybe more, in ink or toner.
