I've done a few experiments that might be of general interest, trying to
print PostScript files on a non-PS color inkjet printer. I suspect that
I do not have the correct driver for GhostView to work with my printer
in color, but even the gray rendition has very jagged lines, presumably
because it rasterizes the image rather coarsely.
I have had better success doing the following:
Save the plot in a PS file, with /COLOR enabled. You can choose
either standard PS mode or /ENCAP for encapsulated PS. Then, should
you have it, fire up Adobe Photoshop5.0. Import the file, and
when it tells you it will rasterize the image, choose RGB rather
than the default gray scale mode. For a quick print, the default
72 bpi is possibly adequate, but I found that I had to go to
300 bpi rasterization to get a good quality plot with uniform line
weight, and characters that had smooth edges. This rasterization
can generate a very large file (17 Mb in the example I did),
and it is not particularly fast to print, but at least you can
use your machine for other things while it is grinding away.
I'd still appreciate other ideas that might not involve so much
messing around! If anyone has had good luck with PCL mode, that
would be of interest.
