After i print out a document from my canon mp460 (connected to the wireless network via airport express) the printer seems to freeze. the display reads "Printing from PC..." and will not print or do anything else. Won't even power down. I have to pull the plug and then I'm able to print again but just that one time again and the process starts over again

Adkinsdave, keep in mind that often having someone remotely connect to your computer with you and perform this task is easier than trying to walk you through steps and potentially missing a step. With that being said, the Airport Express was meant to make setting up a WiFi network in your own home a breeze.
We need to first determine if your Canon PIXMA MX310 has a Mac driver. According to the Downloads page at Canon.com, there are several Mac drivers available for OS X, 10.5 and 10.6: usa.canon.com - simply choose your OS on the pulldown from that website. Once your computer has the driver it needs to communicate with the printer, you can use your Airport Express to connect to the printer.
Obviously, make sure the printer is turned on and once you go through the Airport Express connect guide you should be printing in no time.
Let us know if there are still issues.

Check your printer sharing in the system preferences... make sure it's on.. then when you get the print window, look for your printer under shared printers... try it that way... worked for me on my wifi network here.

Here's what worked for me: I had everything set with my wireless network which included an Airport Extreme base station and two Airport Express units to extend range. I still couldn't plug and play with my printer. 1. You have to plug your printer into the Airport Express, turn it on, then select a document to print from your computer. 2. Select print from the pulldown menu (or select 'command P' on the keyboard). 3. When the print dialog window appears, go to the "Printer:" selection bar near the top of the window and select "print & fax preferences..." 4. This opens a new window, "print & fax." Near the bottom left of this window just below an icon list of your printers are a "+" button and a "-" button right next to each other. 5. Click "+". Yet another window opens which will reveal a list with your printer on it. 6. If you don't see your printer, click the "default" icon in the top left hand corner of the new window. 7. Select your printer, then click "add" on the bottom right hand corner of the window. The window will close automatically and return you to the "print & fax" window. 8. You should now see your printer in the list. You may say, "My printer was already in the list," but that's not good enough. The process you just went through enabled the computer to detect it on your network. You may want to use the "-" button to remove any previously listed printers from the list in the "print & fax" window. 9. Now you should be able to close the "print & fax" window and get some wireless printing done.

Airport Express provides only a print server, not a networked usb hub so it can only print. I'm afraid you'll have to go back to wired for scanning.

you need to in stall the drivers on your computer for the printer. and make sure you phone is not connected to the printer at the time you are trying to use it with your computer as this can cause problems to.

I removed any printer configurations for this printer in both my pc and my mac (both usb and wireless). Then I restarted both computers and added the printer via usb again to each. At that point I went back to the extreme configuration and under the printers tab it was finally seeing Hewlett Packard Laserjet 1020. After that, adding via Bonjour went smoothly on both platforms.

I had the same problem until recently. You have to install the drivers FROM THE CD that came with the printer, instead of selecting the drivers from the default list. Then, when selecting which printer driver to use (you'll have two options) choose Canon IJ and NOT Canon MX310 series. This is a problem with their MX310 driver, which is solved using a default/generic Canon InkJet (hence, the IJ) driver. Hope this helps!
P.S. This only works on Mac OS X. I have yet to figure out how to print wirelessly through Vista. Will keep you posted.

Deanna, if the mfc is not that old, take it back to the dealer and ask for changing it to a wireless printer (extension: CW). Do you really need the fax function? If not, try this printer: DCP 750CW. If yes, get the MFC 845 CW. The CN printer have to be connected directly to router or pc/laptop.

Vista has very little drivers for equipment sad but true. However in your case you can use Airport Extream. However here is what an apple tech had to say: If you are a Vista user and you don't have access to a Mac, you will not be able to get this working. Apple hasn't yet stirred itself to release a version of Airport Express Assistant that works with Windows Vista - you can't set it up via Windows' own networking software and nor does the Airport Admin Utility work under Vista. It installs and you can run it, but it returns error messages if you try and connect to the Airport Express. I had to use a Mac to get it working, though once it's set up as a client to your existing wireless network, you can stream from iTunes on a Vista PC to the Airport Express. The documentation is very poor, too, with this: I had to do extensive Googling first to track down the fact that I couldn't set it up with Vista and second to identify the device's IP address and default password. Having said that, it is a breeze to set up via a Mac and works like a dream witih Vista once it's up and running. But don't bother if you have Vista until Apple updates the software. Was this review helpful to you?

i was told that the printer needs to be directly connected to the imac (not airport) for the scanner to work.
i have the same issue w/ the airport extreme.
