GS and Epson
Stefan,
Try the following version of gdevupd.c and let us know if it solves your
problem.

[mailto:bug-gswin-admin@ghostscript.com]On Behalf Of Radke, Stefan
Sent: Monday, January 20, 2003 10:26 PM

Subject: [bug-gswin] GS and Epson
Symptoms:
After installing GV 4.3 and GS 8.0 I can't print correctly. I get yellow
pages with white letters instead of white/black.GV4.3 and GS7.04 work fine.
Ghostscript version
GS 8.0 for OS2
Hardware
Epson Stylus Color 880 (USB)
.upp Files from http://murakami.best.vwh.net/uppfiles
Operating system I'm using:
OS2 eCS 1.02
Do you have any ideas how to solve it?
Will there be any OS2 solutions in the future?
Mit freundlichen Grüssen/Kind regards

"uniprint" supports a hole bunch of external parameters. This Parameters
fall into the following categories:
0. special-string the upd_version, readonly upd_version
1. choice name-indices, stored in upd->choice
2. boolean single bits, stored in upd->flags
3. integers single numbers, stored in upd->ints
4. integer-Arrays arrays of numbers, stored in upd->int_a
5. string device-commands, stored in upd->strings
6. string-Arrays arrayed device-commands, stored in upd->string_a
7. float-Arrays arrays of floats, stored in upd->float_a
Currently there is no need for single floats, but they may be introduced =
in
future versions. Since "uniprint" somtimes manipulates the contents of =
the
array-variables it dynamically allocates storage for all this =
parameters.
The following sections defines the names for this parameters in the =
order,
they are stored within the mentioned dynamic fields of the =
upd-structure.
A NULL-name means that the corresponding parameter is not externally =
visible.
Besides the name, there is always a symbolic index #defined, that MUST =
match
the Index-Number of the name.

Function: upd_print_page
This is the top-level printing routine. It works through this
steps:
1. Once for each generated file, the "device-open-sequence" is written.
2. The "page-begin-sequence" is written.
3. The data are generated and written:
3.1: Data are converted into a "printer-family"-specific format.
This step includes the halftoning, if selected.
3.2: Data are written with a printer-specific function.
There is not much code-compression inside theese functions,
since i observed to improvments in print-speed. Other
drivers do a better job in this.
4. The "page-end-sequence" is written.
5. If a one-page-per-file mode is selected, the "device-close-sequence"
is added to the output. For multi-page files, this writing is
performed in "upd_close", the drivers close-function.
The routine is quite short, since all the allocation and checking
occur in upd_open and upd_putparams. The only test, that upd_print_page
does, is the verification wether the device is in a sane state. This
must be done here, since during the initialisation, the device is
usually opened several times, before obtaining a valid state.
