Gawd, I hope not... :-O  I tried that dren *many* a time, and it just 
doesn't work. You'll spend more time retracing the traces that didn't trace 
by hand than if you'd have done it with those wacko little RadioShack 
templates and a burnisher!

Oh, did I mention that it's rather expensive for what you don't get? Last 
time I checked, it was around $15 for 5 sheets - when it takes 3 sheets to 
almost maybe make something work...[1]

If you're time is worth more than $0.50USD per hour, it's cheaper (and much 
easier) to invest in a decent hobbyist 'photo-developer' kit.

www.circuitspecialists.com has good prices on decent 'lower-end' equipment; 
well, a lot higher-end than that laser-crap. As usual, the lawyer shiznit: 
I have no affiliation with them other than a one-time satisfied customer 
due to a google search.

Well, that's my take anyway... Laterz,

[1] OK, maybe I'm being harsh -- maybe I was using the wrong equipment. I 
*heard* (but I'm no laser printer specialist or anything) that any printer 
that uses 'microfine' toner needs more heat to do it's job. The two 
printers I tried were an HP laserjet 5L and my QMS MagiColor 2+ [2] -- 
Maybe the printers damaged it in some way, but when they say "any laser 
printer" dammit, it should mean any...

[2] Out of the 2 sheets I ran thru the QMS, one didn't feed, the other 
wouldn't transer at all -- maybe from the Fuser Oil that's necessary on 
those color lasers??? A little warning in the instructions: "Fuser Oil No 
Touchie" would've been nice... ;-)
