>
> I use the dos emulator, dosemu to print from WordPerfect which prints to the HPLJ Colour 4500
>
> There are two machines, both set up in the same way, one prints without problem and the other does not and produces the following error message (in /var/cups/error_log):
>
> "I [29/Jan/2008:09:20:01 +0000] Default destination set to 'HPLJ4500' by 'root'.
> E [29/Jan/2008:09:20:12 +0000] print_job: Unsupported format 'application/vnd.cups-raw'!
> I [29/Jan/2008:09:20:12 +0000] Hint: Do you have the raw file printing rules enabled?"
