scary command line output when file printed

Version: Ubuntu 7.10 gutsy
When run from the command line, and a file is printed, gedit spews out the following. The printer model is a Samsung ML-1210.
The print succeeds, and the job shows up in the print queue. I didn't actually print the document, but I can do that if needed.

Output:

Model not found, discarding config
