Howdy,

I'm using the Brother PS(like) driver (rather than the CUPS driver)  
for my HD-5250DN printer. (Actually, I think you suggested it since  
the CUPS driver wouldn't print certain maths available in the fourier  
package. Thanks again for that :-).)

If I Print Source for a file within TeXShop (with the %!TEX...  
header) I have no problems. Does the PS(like) driver automatically  
wrap the file with a PS header?

Finally, maybe to put this thread to sleep, while I still know it's  
faulty logic to think that `If A then B' implies `If B then A' I will  
admit the (incorrect and illogical) `tradition' that `%!' at the  
start of a file implies PostScript may be well established.

If you use `%%!' will emacsen (etc.) still assume the file is  
PostScript? I ask because TeXShop still recognizes the line as a  
proper setting; e.g. it will still set the proper engine. Then folks  
who use TeXShop to run the engine and display the pdf from within  
emacsen would just add the extra `%' at the head of that line; the  
rest of use need not worry.

Good Luck,
