I have searched the web for a way to increase  the standard setting-resolution, but have not been able to find anything. The 600x600 dpi's is very low for a printer that is designed for 9600x2400 dpi's. 600x600 dpi is not exactly photo quality!

Hello,

This is not a CUPS issue.
I'm the maintainer for the Canon backend in the gutenprint project. You 
should direct your queries to the gutenprint project:

webpage: http://gimp-print.sourceforge.net/
ML: gimp-print-devel at lists.sourceforge.net

To answer your question---and since I just made modifications to the 
iP4300 code last night---it is currently not possible to print with 
multiple passes on Canon devices. So they can only produce the highest 
resolution available in the printhead (usually 600dpi).

The Epson backend already includes such code, and it is my plan to port 
that to the Canon backend as soon as many other jobs---mainly addition 
of many printers and support for more printer modes---have been 
completed. You can stay tuned to more on the gutenprint MLs, and of 
course I welcome any testing you can do with the iP4300!

Best regards,
