[cups] forcing printout in colores, even on pages in b/w

[Matthias Apitz]

Hello,

I own on my home a laser jet printer of the type HP-Color-LaserJet-MFP-M277dw.
which works nicely with cups version:

cups-2.2.10                    Common UNIX Printing System
cups-filters-1.21.6            Additional backends, filters and other software for CUPS
cups-pdf-2.6.1_4               Virtual printer for CUPS to produce PDF files

Since some weeks the printer shows the following problem: all printout
in black and white (i.e. just printing a text file from the shell with
'lpr -Pps file.txt') comes out on the paper with stripes in magenta. A
scanned examlpe is here: http://www.unixarea.de/HP-Color-LaserJet-MFP-M277dw.jpg
If I print something with colors, for example with pictures or from
Libreoffice with text in color, all is fine.

My question is, how could I force the printer via CUPS to always print
in color, even if the text or Postscript file does not have anything in
colors?

My other question, a bit off-topic, is here anyone who can imagine the
reason of this problem with the printer? The printers web admin
interface shows the three color toner yellow, blue and magenta in 70%
and the black one in 50%. Any ideas?

Thanks

	matthias
