To start out with, you need to determine you are using the correct driver. The easiest way i know to do it is to select "print to file" in the print dialog, when asked what file to write, enter "c:\trash.txt" (without the quotes).
Once the file is written, right click and select "open with", then under that, "notepad". If you are using a postscript driver, you should see something similar to what is below. In postscript "%%" is a comment line. If the file is HP/PCL, it will look nothing like this.

Once you are sure you are printing in postscript, go though the driver and look for something that says print b&w. Often without the B&W option selected, printers prefer to print a pseudo grayscale. While it looks nice, it is not a halftone.
Check the printer and drivers setting that toner saving is OFF and edge smoothing is OFF.

Ok. I did what you suggested and came up with this:

So, it appears I am using the correct driver, the toner saver is OFF, but I cannot find a B&W option or an edge smoothing option. Still no luck.
Is it really this hard to set a printer up to print halftones? I was pretty naive. Thought you just bought the printer, installed the driver and messed around with the dots until you found a medium that made the screenprinter happy!
Thanks for all the help. I hope I can get this resolved. I feel like an idiot, not being able to produce the separations for the owner...
