I finally got it to work thanks!!DRIVERS for the CANON Pixma iP2600 are indeed located at:
http://support-asia.canon-asia.com/ as "naildeca" says.
Couple Notes, FYI:
This install took about 5 minutes... easy for a noob like me.
In addition to the two .deb files (the drivers) mentioned by "naildeca" above at this site (the drivers appear when you select the Injet, Pixma, iP2680 printer, Downloads), are the VERY USEFUL Linux install instructions (Ubuntu included) listed if you then select "Manuals":
"IJ Printer Driver Ver. 2.90 for Linux (Operation guide [Explanation of the iP2600series operation (html file)]"
With this wonderful documentation the installation went a bit easier... since there is one install step one must take before installing the .debs.
Noteworthy in these instructions, CANON recommends the following command at the Terminal before installing the .debs, to ready the system to "receive" them. I found this necessary and fundamental:
sudo aa-complain cupsd
The install instructions include a step called "Register the Printer to the Spooler." A sample command is shown, so this is easy to do. However, part of the command needs two things that are peculiar to your computer after you install the .debs.
Printer name and the URI may be easily found at System, Administration, Printing ... and your iP2600 PPD can be found using "locate *.ppd" at the command line.
If it helps, mine was located in /usr/share/ppd/canonip2600.ppd, and after the Registration command, in /etc/cups/ppd/canonip2600.ppd
Some applications need to be told the Printer "PPD" to allow them to understand how to talk to the iP2600, so you may want to save this location in a text file--for later recall or copy & paste.
Thanks to those who forged the path and helped me find the drivers.
i found that i needed to remove and reinstall the cnijfilter-common2 package before i got it to work.
