Postscript also does lines and circles and ...

Usually it gets (much) better results with text than you get from gif/jpg 
when they are targeted for screen resolution.

Keep in mind that the scale factor may be a bit off.  If you draw a 1 inch 
line, it might be slightly more or less than an inch.

It's easy to scale postscript.  My linux system has a psresize command.  (I 
haven't tried it, at least not recently.)  With a bit of trial and error, you 
can get a very accurate result.

I used to print gerber layers for PCBs on mylar.  If you were doing 
mechanical checks, it was worth the effort to get the scale right.  (Maybe we 
just had a crappy printer.)

If you like low level hacking, you can write raw postscript by hand for 
simple things.  I have the first 3 postscript books from many years ago.  I 
pull them out every few years.
