A printer only prints according to the 'numbers' sent to it. the experiment confirms that either your profile, your rendering intent, or your choice of conversion engine is making file values of 255 into 254 when it sends them to the printer, you can try a few different settings and then do convert to profile and re-read the values, if your white remains white, light the cigar. > > My original file was transparent, the theory being that if there is nothing > there, nothing should print!

Transparent in PS is white when printed, as you will see when you flatten an image with transparent borders. Using convert to profile in PS and printing same as source, 'should' be the same as printing and selecting said profile in the print preview dialogue. Check again your rendering intents etc. Also try to use no colour adjustment in the printer settings, it removes one more variable. Finally, if none of this works with your profile, get a custom profile for your printer, see my last post for a guy I've just used.
