Your ULD package doesn't work for you on unstable. Let us see how mine goes on. 1. Go to http://www.samsung.com/uk/support/model/ML-1910/SEE and download uld_v1.00.06.tar.gz. 2. Decompress and unpack the file with 'tar zvxf uld_v1.00.06.tar.gz'. 3. cp uld/i386/rastertospl /usr/lib/cups/filter/. 4. chown root.root /usr/lib/cups/filter/rastertospl. 5. cp uld/noarch/share/ppd/Samsung_ML-191x_Series.ppd /usr/share/ppd/custom/. 6. lpinfo -m | grep ML-191x. 7. lpadmin -p ML191x -v file:/dev/null -E -m lsb/usr/custom/Samsung_ML-191x_Series.ppd. The last five steps are done as root. Now (as root again) 8. cupsfilter -p /etc/cups/ppd/ML192x.ppd -e -m printer/foo message.txt > out.prn 2>log. log and out.prn have been compressed and attached to this mail. Uncompress with gunzip. Note that the log shows all filters being run successfully. As far as I am concerned, cupsd and the filtering system have worked well. message.txt contains a secret message for you. out.prn is a file which can be sent directly to the Samsung printer. But I haven't got such a printer, you say. Ah, but *you* have. So do cat out.prn > /dev/usb/lp0 You can now reveal the message to everyone. An invitation: any of the hundreds of list readers with a USB connected Samsung printer which accepts SPL can have fun trying to print the file too. -- Brian.
