Description of problem:
I'm excited that my ALPS MD1300 is at last getting some Linux support.
Alas there are problems.
is a 17K PostScript file that demonstrates a bug in the Steinberger
32bpp dithering as implemented in the md2k filter and used to drive
an ALPS MD1300 printer.
If you set "Simple Color(4bpp)" this file prints fine. (It's the
latter portion of my home page rendered by Mozilla.)
If you set "Steinb. High Qual (32bpp) only the Magenta layer prints
onto the page.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. fetch the postscript file
2. set Steinberger 32bpp mode
3. Print this file on your ALPS MD1300
4. set 4bpp simple mode
5. Print this flie on your ALPS MD1300
6. Notice the difference.
Actual Results: Only the Magenta printed.
Expected Results: Proper rendering of the page, including the text in

Red Hat Linux is no longer supported by Red Hat, Inc. If you are still
running Red Hat Linux, you are strongly advised to upgrade to a
current Fedora Core release or Red Hat Enterprise Linux or comparable.
Some information on which option may be right for you is available at
Red Hat apologizes that these issues have not been resolved yet. We do
want to make sure that no important bugs slip through the cracks.
Please check if this issue is still present in a current Fedora Core
release. If so, please change the product and version to match, and
check the box indicating that the requested information has been
provided. Note that any bug still open against Red Hat Linux on will be
closed as 'CANTFIX' on September 30, 2006. Thanks again for your help.
I think I gave that printer away a couple years ago.
I would say that sweeping through and closing all the bugs that really are NOT going to get addressed
is a good step forward to focusing on answering bugs in a timely manner. I agree that you should
CLOSE as WONTFIX, and I hope that other bugs opened in the future will be resolved more quickly.
I think we should have done this with the bug 3 years ago. Unfortunately, at that time we didn't know
that the ALPS 1300 would fail to become an interesting printer, or that there'd be a protracted lack of
