I have an HP Dekjet 930C printer that I use with my iBookG4 and when I print, the printer doesn't print in color or fine background grey print. I replaced the color ink cartridge and still no color prints. Black ink and text print well, but fine print on coupons for example that are in light grey printed from the internet either don't appear or come out very faintly even on the "best" print quality setting. I have the printer set to print in color, even color backgrounds. I'm sure all the settings are fine because it worked fine before. Do you think mostly likely I have a bad ink cartridge? Thank you for any insights.
