One dot of the average 1200DPI printer is about 1 mil, so it is not  
surprising it doesn't form a good line one dot wide.
You already know what you can reasonably do - around 5 mil, and that is  
about the same TT or potoprocess.

You could have your artwork professionally printed, but the restrictions  
due to etching won't allow you to make a much better PCB anyway, so it is  
probably not worth the cost.
You might also try one of the high resolution inkjets, maybe they make  
better lines.
