Cannot print to a Canon networked printer

There's a new printer driver from just last month at Canon's web site. DL and install it to see if that resolves your problem. I'm printing on my in-laws' Epson printer that is connected by USB to their WinXP machine without problems (but am using 10.5.1).

 

The .dmg file is a disk image. When it downloads, double click on it if it doesn't automount as a virtual hard drive. In this vhd should be the driver installer for the printer. You must run this installer on any Mac from which you wish to print to that printer. After you successfully run the installer and the driver is installed (which may or may not require you to reboot - the installer will let you know), then you will have to select that printer from the pull-down of the print dialog box from which you are trying to print. Depending on whether you're using 10.4 or 10.5 it's a bit different, but either way you likely will have to navigate the pull-down to select the driver for that printer.

It's not this complicated if the printer is connected to a Mac because Macs query printers for this vital info and setup is pretty much automatic. Unfortunately, Windows does not, thus the need to explicitly tell the Mac what the printer is (since Windows will not collect that info and tell your Mac what the printer is). You're close.

One more thing; the PC that the printer is connected to cannot be in 'sleep' mode, otherwise you're computer cannot see it. Windows is clunky.

 

If you are running Leopard (10.5) your computer should already have the drivers for the MP450:

No need to install drivers unless you're on 10.4.
