lpadmin: add-printer (set model) failed: client-error-not-found

[Jacob Friis Larsen <webcom.dk@gmail.com>]

I'm trying to follow a guide that will make my Debian able to print to
a Windows printer.
Guide: http://www.linux.org.za/LDP/HOWTO/Debian-and-Windows-Shared-Printing/index.html

But I get an error I don't know what to do about:

# /usr/sbin/lpadmin -p BrotherPrinter -v
smb://user:pass@desktop/Brother -P /root/laser.ppd
lpadmin: add-printer (set model) failed: client-error-not-found

Any ideas?

Thanks,
Jacob
