Homebrew PCBs

I've etched a couple of great boards using the Pulsar toner transfer paper and green foil.

The problem I've had is my laser printer doesn't produce accurate artwork. It's not even consistent from page to page, so I haven't had any luck trying to scale the original image to get an accurate print.

This is exacerbated by my wanting to use my CNC router to drill the holes. Holes that are a little off when hand drilling are OK, but not so much when CNC drilling.

Does anyone use a laser printer that produces repeatable and accurate artwork?
