Najprije napravite fajl cupsys istovjetan fajlu cups iz shella:
 sudo cp /etc/init.d/cups /etc/init.d/cupsys
Skinite drivere sa [http://ubuntubee.blogspot.com/2008/02/canon-pixma-ip1800-and-ubuntu.html ubuntubee.blogspot.com]  
Potom ih treba obraditi sljedećom skriptom:

 #!/bin/bash
 EDITOR=gedit
 if [[ -z "$1" ]]; then
   echo "Syntax: $0 debfile"
   exit 1
 fi
 DEBFILE="$1"
 TMPDIR=`mktemp -d /tmp/deb.XXXXXXXXXX` || exit 1
 OUTPUT=`basename "$DEBFILE" .deb`.modfied.deb
 if [[ -e "$OUTPUT" ]]; then
   echo "$OUTPUT exists."
   rm -r "$TMPDIR"
   exit 1
 fi
 dpkg-deb -x "$DEBFILE" "$TMPDIR"
 dpkg-deb --control "$DEBFILE" "$TMPDIR"/DEBIAN
 if [[ ! -e "$TMPDIR"/DEBIAN/control ]]; then
   echo DEBIAN/control not found.
   rm -r "$TMPDIR"
   exit 1
 fi
 CONTROL="$TMPDIR"/DEBIAN/control
 MOD=`stat -c "%y" "$CONTROL"`
 $EDITOR "$CONTROL"
 if [[ "$MOD" == `stat -c "%y" "$CONTROL"` ]]; then
   echo Not modfied.
 else
   echo Building new deb...
   dpkg -b "$TMPDIR" "$OUTPUT"
 fi
 rm -r "$TMPDIR"

i to na način da uklonite retke koje sadrže depedencies. 

Dakle gornju skriptu spremite u npr. dep.sh 

Promijenite ju u izvršnu datoteku sa:
 sudo chmod u+x dep.sh
i koristite iz terminala 
 sudo ./dep.sh ime_fajla.deb
Obradite oba fajla (drivera). Dobijete 2 nova pakiranja koja instalirate dvoklikom. Najprije common, pa zatim ip1800. Printer uredno radi u kolor modu!

Evo caka kako ip1800 radi crno-bijelo. Otvorite ppd file /usr/share/cups/model/custom/canonip1800.ppd na dno dodajte

obrišite i na to mjesto dodajte

 *CloseUI: *Resolution


te snimite file. 

Sad taj file treba koristiti. Preko web-preglednika uđite u CUPS sa 

 http://localhost:631 

birajte 

 manage printer 

pa 

 modify printer 

i nastavite dok vas ne pita ppd file. Kliknite dugme i idite do prerađenog ppd fajla i potvrdite ga.

Zatim preko System-Administration-Print nađite printer desno (sekundarno) ga kliknite i birajte Properities. Tu detaljno konfigurirajte printer, a najvažnije je staviti kvačicu na checkbox "grayscale". Restartajte CUPS naredbom is shella kao root

 sudo /etc/init.d/cupsys restart

ili restartajte kompjuter. Sad vam boje ispisuje u raznim sivim nijansama u što ćete se uvjeriti printanjem test stranice.
