Maybe this is a little more clear:

(a link from the webpage: www.nec.com | products | printers | 860 )
Adobe Systems Inc.'s inexpensive PrintGear system speeds the printing 
process by dovetailing a new printer driver with a new dedicated 
image-processing chip, the 50MHz PrintGear Imaging Processor.

The driver sends page data as RISC-like image operators to the new 
chip. In addition, the new technology dedicates a 16MHz 68EC000 
coprocessor to managing I/O functions. This driver also manages the 
printer's PCL 4 emulation mode.

Now, you might note that this doesn't say GDI.  In fact, I've read some 
reviews that draw a distinction between PrintGear and GDI, although I 
don't have enough knowledge to comment on this.  I said GDI because 
those were the words NEC used when they replied to me (I asked if the 
860 was compatible with Linux, a Unix-like os, and noted the PCL 
emulation mention). As you, NEC and I have each noted, PCL is emulated; 
i.e.: you have to run the base driver first.  In this case, that's 
Adobe's PrintGear.

Adobe markets PrintGear to the low end: primarily toward windoze and 
mac, with some mention of os/2, no unix.  One might conjecture that 
PrintGear competes against Adobe's own PostScript at the low end, that 
PostScript is marketed more at the high end of the market, and that 
traditionally unix users are at the high end, so there's probably not 
much demand for a unix driver for PrintGear in Adobe's marketing 
department. This doesn't mean a PrintGear driver cannot be written for 
Linux, but PrintGear is relatively new, so I wouldn't expect to see one 
anytime soon.

If you want to know the details on PrintGear, try this:
