Homebrew PCBs

Although I have been making successful single-sided PCBs for a while now, I just recently decided to try making a double sided board with SMD (.5mm TQFP) parts. So, I went out and bought a new inexpensive Samsung ML-2165 printer. The problem I am having is getting the scaling right. It's inconsistent and varies from print to print. Plain paper works pretty good, but the Pulsar paper comes out too short. I tried adjusting the scaling in the Kicad print dialog, but it seems to come out either too wide or too short. Very frustrating, and I have wasted four sheets of TTS paper so far.
I have a couple of boxes of HP glossy photo paper, so I may try that.

Any advice?

Thanks,

Pete
