HP Laserjet 1020 printing negative images and photos. Text prints fine

HPLIP software version 3.11.3a.
Operating System Opensuse 11.4 x86_64
HP Laserjet 1020 printer prints good text from any application, but when printing images or photos printed on the paper negative.
If the application is tested with Version 2.6.0 Gwenview
Using the KDE Development Platform 4.6.0 (4.6.0) "release 6. and in the print options you choose grayscale print correctly. In the color printing option in the negative.
Firefox 4.0 with openSUSE 11.4 for printing the pictures of web pages in the negative. Firefox does not have the grayscale option in print.
Thanks

The original installation of OpenSUSE 11.4 (64 bit) version is 3.11.1.19 HPLIP which expresses the same problem mentioned before with the HP Lasejet 1020 (printed in negative images of any application).
Tested with an HP Laserjet P1006 and prints correctly.
Updating HPLIP Version 3.11.3a was made from the website: http://www.opensuse.org/es/ in one click to install section was added to the repository from yast and then updated only from the same YAST.
The output of "hp-check-t" is:

Note: hp-check can be run in three modes:
1. Compile-time check mode (-c or --compile): Use this mode before compiling the HPLIP supplied tarball (.tar.gz or
.run) to determine if the proper dependencies are installed to successfully compile HPLIP.
2. Run-time check mode (-r or --run): Use this mode to determine if a distro supplied package (.deb, .rpm, etc) or
an already built HPLIP supplied tarball has the proper dependencies installed to successfully run.
3. Both compile- and run-time check mode (-b or --both) (Default): This mode will check both of the above cases
(both compile- and run-time dependencies).

La impresora HP Laserjet 1020 imprime bien los textos de cualquier aplicación, pero al imprimir imagenes o fotos las imprime en el papel en negativo.
Si se prueba con la aplicación Gwenview Versión 2.6.0
Usando la plataforma de desarrollo de KDE 4.6.0 (4.6.0) "release 6". y en las opciones de impresión se elige escala de grises imprime correctamente. En la opción en colores imprime en negativo.
con Firefox 4.0 para openSUSE 11.4 imprime las fotos de las páginas web en negativo. Firefox no tiene la opción de escalas de grises en la impresión.
Gracias
La instalación original de OpenSUSE 11.4 (64 Bits) del HPLIP es la versión 3.11.1.19 la cual manifiesta el mismo problema mencionado antes con la impresora HP Lasejet 1020 (imprime en negativo las imagenes de cualquier aplicación).
Se probó con una impresora HP Laserjet P1006 e imprime correctamente.
La actualización de HPLIP Versión 3.11.3a se realizó desde la página web : http://www.opensuse.org/es/ en la sección un click para instalar se añadió el repositorio desde YAst y luego se actualizó solo desde el mismo YAST.
