Hello Robert,
this is what I expected especially when I remember the discussion
about paper sizes and the canon driver last February/March.
So I was surprised to have no problems with the standard print dialogs
in various programs. I did not expect problens with the gutenprint
print dialog in GIMP. Same problems with PhotoPrint.

It happens is that the print job is sent to the printer but the printer
shows no sign of reaction. I can see the data is transmitted because the 
printer is connected via WLAN and I can see the network activity
in the system monitor.

These are my settings in the gutenprint print dialog in GIMP:
Media Type: Photo Paper Plus Glossy II
Media Source: Cassette
Cassette Tray: Upper Tray/Cassette 1
		(no change if set to 'Driver-Controlled')
Resolution: 600x600 DPI PHOTO HIGH
	also tried all other resolutions to no avail
Ink Type: CMYK Color (no real choice here but 'Black')
	(this is changed to 'CMYKk Color' automatically when I set Resolution 		
	to 	'600x600 DPI HIGH (Duplex)')
Ink Set: None (no other choice)
Print Quality: Standard (no change if set to 'Manual Control')
Borderless button is pressed. (no change if released)
Image Type: Photograph (no change for other values)
Paper Size: 4x6 (also tried  'Postcard', '10cm x 15cm')

The working settings in standard print dialog are:
Paper type: Photo Paper Plus Glossy II
Paper source: Cassette
Paper size: 10cm x 15cm (also working 'hagaki (postcard)' and '4x6'
	with no visible changes on output)
Resolution: Automatic (but all others work with no visible changes)
Color Precision: Best
Print Quality: Standard
Shrink Page If Necessary to Fit Borders: Crop (preserve dimensions)
Cassette Tray: Upper Tray /Cassette 1
Ink Type: CMYKk Color
Borderless: Yes	 (Only true for left edge, but this might be a GIMP issue)

The borderless issue I can circumvent by creating a exact fitting
image with PhotoPrint and send that via shell command to an
approprialely setup queue. Then the results are perfect.

Sorry if I missed the obvious and consumed your time and bandwith.
