I even found an alternate source for the version 170 drivers (that had a different file name - o84benx.dmg) and uninstalled the previous drivers and tried installing from this file - it said the install was successful - but they still don't show up in the setup list. and when I tried to perform a setup, the PRINT drivers still don't show up in the list of Canon printers. (of course the install process made me restart the computer). and then I reinstalled version 170 PRINT drivers.

So I uninstalled version 161, and uninstalled the fax drivers (version 210), shut the computer down, restarted it, tried another printer setup, and now the Fax drivers are missing (as they should be since I uninstalled them) and the PRINT drivers are not showing up either (as they should be). Same thing - the PRINT driver doesn't show up in the list during setup (but the FAX drivers are still there). I then did a search on the internet, and saw that there was an older version of the PRINT driver, version 161, so I downloaded it, uninstalled version 170, and installed version 161. But that's fine for Faxing, but does NOT let you print. Although I don't expect to use it to fax docs from my computer i finished the FAX setup anyway, and gave it a try, and it shows up in my available printers and responds exactly as it should. When I go to setup the printer again, the FAX driver shows up, just as it should, but the PRINT drivers are still not in the list. I then went back to the Canon web site and saw they had a Fax driver for the printer, so I downloaded it (it's version 210) and installed it.

But when I try to setup the printer in the printer control panel, I set up an IP printer and supply the IP address the printer is set for, but when I try to select the driver, I choose Canon, and the list of canon drivers shows up, and although other Canon models show up in the list, the MF4270 is not in the list. I started by installing the UFRII version 170 software, and the installer claims that the software was properly installed. The REAL problem is getting my Mac's printer system to recognize the driver software. In fact, when I try to access the printer via my browser, the printer responds perfectly. Since the PCs can print to it with no problem we KNOW that it is connected properly and responding to network access/traffic. The problem came when I tried to get my Mac to talk to it. The printer had a setup CD that came with it, and it worked perfectly for the two PCs that she uses in her office. Therefore the USB connection is not being used at all (the printer is not connected directly to any computer - access is only through the network). Since she has a PC and I have a Mac we elected to set the printer up as a network printer (I gave it a fixed IP address). We (me and my wife) bought a Canon MF4270 today.
