I have few images compressed with Adobe Photoshop's "Adobe JPEG
Compress" Plug-in and they are in PostScript format. The header states
that I must have a level 2 printer to print these with, but when I try
to print them with my LaserWriter IIf, it only gives an PostScript error
(%% Image - TypeCheck ...%%)

What to do? Where is the problem?

Here's the header if someone is interested (from a grayscale pic):
