I have a student working in the studio right now who is using ink jet transparencies on a high quality Epson film to expose polymer plates. She pumps things up a bit in curves to insure that the ink is dense-- and it is completely black. Her printer outputs at 1440 dpi. The line art and text look great so far. Next we'll be playing around with high resolution halftones if she gets the research grant for which she applied. I'll keep you all updated.

I don't remember a thread on this so I'm guessing you are asking
whether separations can be made on a laser printer for four color
If so, yes they can. The separations could be made in Photoshop (or a
page-layout program) and printed separately on transparencies. You
would want at least a 1200dpi printer (CRC quality). A spray-on
product called Laser Buddy (used by serigraphers) can enhance the
toner to the point where you will get adequate density.
I would not have believed this myself but this weekend a Laser Buddy
enhanced transparancy was brought in and though the thing looked like
total crap the processing went well and the letterforms' edges looked
quite sharp. I did not proof this but I was told it printed well.
If, on the other hand you are asking if plates be made from a color
laser print, I'd have to say no, unless there is something about the
letterpress process that I missed along the way. And I'm not
