Question about Canon PIXMA MP830 All-In-One InkJet Printer
I am TRYING to print a color photo I converted to b/w (using Photoshop) from a MacBook to my MP830 - on photo paper. I can print to regular paper - but w/ poor quality. I cannot, however, print to photo paper - the images come out green! I've tried various file types, various media options, everything - suggestions?
You need to convert to true black and white by discarding the colour info in photoshop - Open the photo you want to convert to black and white. Choose Image > Mode > Grayscale. When asked to discard color info, click OK. Photoshop converts the colors in the image to black, white, and shades of gray. if you keep the colour info, you will get the composite with all 5 ink colours as Jackboy describes, although it will appear black and white on the screen. With colour info removed, only black ink should get used unless there is a problem with the print head - possibly needs deep cleaning. for instructions on how to do this go to; http://www.usa.canon.com/consumer/controller?act=ModelInfoAct&fcategoryid=123&modelid=12804 then under "tech support" select "frequently asked questions" then type "deep printhead cleaning" into the "please ask your question" box. sorry the Canon site doesn't allow me to post a direct link. If you think you will want the photo in colour again later, make sure you save it separately first. hope this helps :)

The paper you print on is not relevant. What happens is the green tint is the actual printer delivering all the colours to give a 'composite' black. On shiny photo paper this is emphasized where as on plain paper the colour is absorbed and shows as intended. So what can you do? Move away from black and go for a tint such as sepia.
