Same printer here, HP1220C with Kubuntu 8.04.
I worked with V.184.108.40.206 without problems.
To see my printers on dialog i use the command: ln -sf /var/run/cups/printcap /etc/printcap.
After that, portrait and landscape printing were printed well.
On 220.127.116.11 my HP1220C stop to print in landscape mode.
My other Samsung Laser still print in landscape mode very well.
On HP1220C all my drawing are cutted on the right side; If I print A4 paper in landscape mode first 9cm are blank and next 21cm correctly printed in landscape mode with the drawing cutted on its right.
This is a scan of HP1220C A4 printed with 18.104.22.168

I need my Hp1220C to print in A3 landscape.
Now I draw on 126.96.36.199 and print in 188.8.131.52; It's no good!
