Lawyers are not a problem -- the PS _language_ *IS* in the public domain.
Anyboy is free to implement their own interpreter. See -'ghostscript' for
a _very_ well-known example. <grin>
Many "lower-price" printer manufacturers use a 'private' implemention -- the
Adobe License fee is (or at least used to be, a couplee of decades aoo, when
I was dealing with such things) in the hundreds of dollars _per_unit_.
Even higher priced models. HP uses a compatible version in many of
their office printers. It's very good.
I haven't tested a current Brother implementation. A couple of decades ago,
their 'PS-level 2" implementation 'just worked' for anything I happened to
throw at it in a production environment.
Some of the 'alternative' implementations actually have -fewer- bugs in them
than the genuine Adobe-licensed code does. <wry grin>
Been a long time since I tried BRScript, but memory suggests it was
adequate then, and will have improved since. Machine-generated PS code
generally doesn't try anything unusual, and should work fine.
The ability to print PDFs directly was added with PostScript 3.
Pretty much any printer with a PS interpreter will also accept PCL.
Interpreting the PS on the host with ghostscript and then sending PCL
bitmaps might be faster. It depends on the document and the bandwidth
to the printer.
