After updating to O/S Big Sur I was able to access the MP990 purchased long ago.
However, I cannot change any printer settings.
Previously, the MP990 offered many settings.
But now, I can only use the default settings, and I can't determine the default settings.
I need to print "plain" documents.
1). How can I print to the MP990 in Black & White-- abd only Black & White?
I don't want the printer using any color cartridges.
I purchased the MP990 to generate photo-qaulity output.
2) How can i create photos using the MP990?
