pwillard, what paper are you using? I've just today used a new paper, it's Genuine Parchment paper,Oven safe to 420 deg F, 30 Sq FT 24ft x 15 inches @ Cost $2.45 USD. That stuff works good!
I just did a 2X3" board with traces and full ground planes. Ran thru twice at 300F and the paper just slides off with NO trace of toner left on paper, nor any paper on PCB. The traces look good and dark - the ground plane does have some thin spots, but since there is no toner left on the paper I have to lay that blame to the HP P1006 printer as it was starting to show those light spots on Pulsar and HP Presentation paper. I have 500 pages on a starter toner so that might be the problem... low toner?
One thing that just occurs to me - double sided boards. The parchment paper is so thin and slick it might be hard to hold in place while lining up both sides.
I think it's still best to setup for my own PCB stuff - the laminator is only $25 delivered, the laser printer is a replacement for inkjet. To me, the BIG thing is I can do prototyping with PCB which requires me to etch up a board, then as I build it find how it needs changed, and make another board - and I can have a board in less than 30 minutes after finishing the layout in a program.
After buying the $25 laminator and with the laser printer, the cost of a PCB is only a couple of bucks for PCB, etching chemicals, bits, etc. the PCB can be anything from a 2X2" board to a 4X6" board (my largest todate).
