In any case, the happy ending is that the problem is soluble: using the printer's firmware for B&W prints. In the case of Canon printers operated from PCs, switching back and forth requires two changes: both a change in the software and a change in the dialogs for the printer's firmware. There is a specific option for B&W printing in the top page of the printer dialog. When you want a color print controlled by software, you have to uncheck that and then separately turn "color matching" to none on a different page.
