I Assume "real" means real milling machine /
drilling machine or something specific to PCB
or engineering.

Real plotters use HP/GL
Real printers use postscript or PCL
Real photo-printers (often) use TIFF

My photoplotter will also be used to make photo
tools for screen printing. That will be
inherently raster stuff rather than bitmaps.

Someone else has written the software to
convert gerber to bitmaps so I dont have too :D

There are lots of different standards out
there. I would have liked to use one of
them rather than make up my own.

Yes - but by some software someone else
has written and that is also probably
already availabe cross-platform.

You do understand the concept and
advantages of making the machine just a
terminal that accepts a file via x-modem
don't you ?
