I have created text in a grey tone. These are the colour settings for the text



When I create a PDF and then print, my printer uses a combination of colours to achieve this grey. I have attached a copy of the .svg file.
Is there a way to create the PDF so that it is using the black toner to print?

OS: Win7
Inkscape v: 0.48
Printer: Canon MG6250

It is possible with ghostscript to convert the pdf from devicergb as described here:

Hi.

Some (most?) inkjet printer emulate grey-scale using colors as the black ink is either too dark or you will get dithering patterns in (http://en.wikipedia.org/wiki/Dither) your prints.
Some photo printers get around this by having several different black inks.
My Epson uses three black cartridges where one can swap Glossy for Matte black depending on the required output.
Most printer drivers will enable you to set "Grey-scale mode" to use the black ink only.
Even if your PDF's contains greys only the printer will still use colors - unless the printer is set to grey-scale mode.
Examples from some of my printers:







Check your printer setting to see if your printer can be set to greyscale.
