Canon MP250: How to add fast greyscale option? (Solved)

#1 Post by jackieflorida »

The pet file for the MP250 works great and I have the printer running.
However, the only print option is RGB at 600dpi.

I want to add a fast greyscale option as can be done quickly and easily in Ubuntu.

How can I do this in Puppy 5.20?

I can't tell from the Ubuntu link how they do it. They may be adding a section to the CUPS PPD file to enable grayscale printing. Or they may be adding that option to the print job on-the-fly.

Have you actually done this in Ubuntu? If so, locate the PPD file and post it here. Look in the folder /etc/cups/ppd.

The following procedure (taken from the German link) works with my MP490.

1. Go to the folder /etc/cups/ppd and locate the PPD file for your printer.

2. Open it in a text editor and go down to about Line 66. You should see the section for "Color Model".

3. After that section at around Line 70, add the following:

Code: Select all

*OpenUI *CNGrayscale/Grayscale: PickOne
*DefaultCNGrayscale: false
*CNGrayscale false/Off: "false"
*CNGrayscale true/On: "true"
*CloseUI: *CNGrayscale
4. Run the CUPS web interface, select your printer and open Set Options. In CUPS 1.4, look under the Administration tab.

5. You should now see a Grayscale option. Select it. Then click the "Set Options" button.

6. Print something that has color.

That's why Ubuntu is so much bigger than Puppy. They have built their own user interfaces to do this kind of thing.

Thank you rcrsn51. It works perfectly.

Yes, actually in LinuxMint10. I no longer have that installatiion but when I reinstall it soon I will try to remember to post the PPD file then.

Now, is there a configuration that can be added to achieve 300dpi color printing? The 600dpi only configuration consumes too much ink for daily printing.

Turboprint offers this but I don't like it.

Go to the German site here referenced by your link. It has the code for several other options.
