For the record, Ubuntu 9.10 comes with a driver that works for the MP500 out of the box, which I was very happy to see! @SomeName: Thanks for the post.

The accompanied problem however is not. I just tried to install the "Canon PIXMA MP550" and after a rather long search for suitable drivers (Gutenprint, etc. pp.) I finally chose to install the drivers provided by Canon: "cnijfilter-common-3.20-1.i386.rpm" and "cnijfilter-mp500-3.20-1.i386.rpm". This, of course, didn't work (same problem: CUPS accepted printing job but didn't print) and after digging deep through log files and juggling config variables I finally tracked the ostensible culprit in the CUPS error log file: "Error: invalid printer model name" (It was right about then that I found this blog entry) So I had the same problem but I didn't want to downgrade CUPS, as was suggested here. So I "strace"d the program "cifmp550" and found the real culprit: "$> strace ./cifmp550 … brk(0x8077000) = 0x8077000 open("/usr/lib/bjlib/cifmp550.conf", O_RDONLY) = -1 EACCES (Permission denied) write(2, "Error: invalid printer model nam"..., 34) = 34 close(0) = 0 exit_group(0) = ?" So in my case, instead of downgrading CUPS, a simple $> chown lp:lp /usr/lib/bjlib/cifmp550.conf sufficed. I hope this helps people who have the same problem and happen to stumble onto this page… and thanks to you Mr. Chai for linking the error message to the misbehaving program (else my search had probably continued).

I just tried to install the “Canon PIXMA MP550″ and after a rather long search for suitable drivers (Gutenprint, etc. pp.) I finally chose to install the drivers provided by Canon: “cnijfilter-common-3.20-1.i386.rpm” and “cnijfilter-mp500-3.20-1.i386.rpm”.

This, of course, didn’t work (same problem: CUPS accepted printing job but didn’t print) and after digging deep through log files and juggling config variables I finally tracked the ostensible culprit in the CUPS error log file:
“Error: invalid printer model name”

(It was right about then that I found this blog entry)

So I had the same problem but I didn’t want to downgrade CUPS, as was suggested here. So I “strace”d the program “cifmp550″ and found the real culprit:
“$> strace ./cifmp550
…
brk(0×8077000) = 0×8077000
open(“/usr/lib/bjlib/cifmp550.conf”, O_RDONLY) = -1 EACCES (Permission denied)
write(2, “Error: invalid printer model nam”…, 34) = 34
close(0) = 0
exit_group(0) = ?”

So in my case, instead of downgrading CUPS, a simple
$> chown lp:lp /usr/lib/bjlib/cifmp550.conf
sufficed.

I hope this helps people who have the same problem and happen to stumble onto this page… and thanks to you Mr. Chai for linking the error message to the misbehaving program (else my search had probably continued).
