Dapper chokes on printing graphics

[Dave M G]

Ubuntu Users,

I'm using Dapper 6.06 LTS. I installed CUPS, the Gnome printer manager, 
and the necessary drivers for my Canon USB printer.

Then I tried to print a test page. I was thrilled to see it start 
printing. And then depressed to see it stop printing... half way through 
the page.

I waited to see if eventually the page would finish, but after a quarter 
of an hour I figured it had stalled. So I reset the printer, turned it 
off and on and waited a bit, then tried another test page. It halted in 
the exact same place. Just a little less than exactly half way.

I tried printing in other applications. From Thunderbird I could print 
an email, and from OpenOffice I could print at a page of text.

 From PDF Viewer and XPDF I could not print anything. With FireFox, I 
tried printing a page that had some images on it, and it choked half way 
through the first page.

My amateur guess as to what the difference with these things is that 
things that are just text seem to print, graphics seem to choke. But I 
don't have any good idea about what would be the reason why graphics 
would choke. Is it the size? The use of the colour ink?

Am I missing some obvious package or driver or something that 
facilitates graphics?
