Ghostscript comes as a seperate disk with the TurboPrint 7.x package.
I haven't got the faintest idea how to get it to work, nor do I know
how to send it a file.
The requirements seem quite big though, something about 64mb to print
a 24-bit picture?
There's Ghostscript equivalents on Aminet but I think the TurboPrint
package is your best bet.
