Well, sort of. But it will not support all the level 2 features. For
example, you will not be able to specify a colour in (say) CIE XYZ and
have it come out that colour on your printer - which is a major reason
many people want level 2 printers in the first place. What will happen
is that the DPS interpreter will calculate the RGB values required
for your _screen_ to display that colour. The printer, on getting
those values, will print out a colour based on dumb RGB->CMYK
conversion, not the colour you would have got with a true Level2
interpreter on your printer.

Also, I suspect that using DPS to render at, say, 100dpi and then
sending this lo-res bitmap to a colour imagesetter is not the route to
high quality ;-)

Of course, I am not knocking NeXT in any way by these comments. They
have done a fine job in getting a DPS together based on Level 2, and
will hopefully spur other DPS vendors (DEC, SGI, and now Sun) into
following suit.

DEC, are you listening? When does the upgrade come out for my DPS?
