In Windows, if I've done something that I think has/will cause system instability I can run System Restore to get me back to a time when I knew I had a good configuration. Last night I was trying to get my Canon Pixma IP5200R printer which has already been set up and on my network to work with my MBP. Using the System Preferences > Printers tool didn't seem to find it. So I went to the Canon web site and installed the latest driver. This didn't do anything (that I can find) I then downloaded the printer Setup Utility for Mac. That didn't want to work unless I plugged it in via USB. So I installed the Canon IJ Network Tool. I can't even find that after installing. I'd like to get rid of this Canon software now. I threw the Setup Utility in the trash but I can't find the IJ Network Tool to do so. Also, how would I uninstall a driver? If I can't find these things to throw them out is there anything else I can do short of clean installing Mac OS? Is there "System Restore" functionality maybe? Thanks!
