The m2300w driver
requires that Ghostscript is installed on the system (as /usr/bin/gs),
and the correct operation of the driver heavily depends on the correct
functioning of Ghostscript.
Basically, the m2300w
driver is supposed to work with different versions of Ghostscript:
However, the color matching of the m2300w
driver is based on CIE-based
color rendering and PostScript
level 3 color management features, which seem to work best with AFPL Ghostscript 8.xx. For printing
of images, gs 8.xx also gives better color rendering, with e.g. less banding
artifacts in color gradients.
We've also encountered a few PostScript documents, which did not print correctly in conjunction with our driver framwork and gs 7.xx (due to an apparent bug in gs 7.xx), but which did work fine with gs 8.xx. But you shouldn't overestimate the latter problem, since every Ghostscript version is buggy, and gs 8.xx may have different bugs. We'll also attempt to find a workaround for this problem.
Current Linux distributions
usually include either GNU
Ghostscript 7.xx or ESP
Ghostscript 7.xx. The apparent reason why they do not include gs 8.xx yet,
seems to be that AFPL Ghostscript 8.xx is not distributed under the terms
of the GNU GPL, but under the terms of the AFPL license, which does not
fit with the business models of Linux vendors. The AFPL license basically
grants free usage, but limits redistribution.
AFPL Ghostscript 8.xx is available from http://www.ghostscript.com. The drawback is, you need to compile it from the sources. If you are an experienced Linux guru, this won't be a problem for you. But if you are a Linux newbie and/or don't feel able to compile and install AFPL Ghostscript 8.xx yourself without help, then rather live with the ghostscript version that comes with your Linux distribution and DON'T consider upgrading ghostscript.
For the convenience of all m2300w
users who do not want or do not have the know-how to build ghostscript
from the sources, we have built a binary RPM package of AFPL Ghostscript 8.xx which we distribute below under the
terms of the Aladdin
Free Public License.
Don't download the package, if you don't agree with the licensing terms.
This RPM package was built on SuSE Linux 8.1, but it will likely
also work with other Linux distributions which support packages in RPM
format.
It is considered as "goodie"
and is not part of the m2300w driver. If the package works for
you, then your're lucky, otherwise just don't use it and compile and install
ghostscript 8.xx yourself, or live with the ghostscript version of your Linux distribution.
The m2300w-ghostscript
package only contains Ghostscript 8.xx, but it does not contain
any fonts. Therefore you always need to install the ghostscript packages
from your Linux distributions in additition to m2300w-ghostscript. If the m2300w-ghostscript
package is installed, then the m2300w driver still executes /usr/bin/gs
(from the Linux distribution) in order to locate the installed fonts,
and then runs /usr/share/m2300w/gs/bin/gs to "rip" the PostScript documents.
Ghostscript is not part of the m2300w driver, but a separate product. In fact, it is a very complex product. It is maintained at http://www.ghostscript.com. Please understand, that we cannot and DO NOT PROVIDE SUPPORT FOR GHOSTSCRIPT. So please don't ask the m2300w team for help if you e.g. attempt to build ghostscript from the sources and run into problems. Sorry for this inconvenience.
