Can't print black/white photos
Actually there is no solution to this "problem" nearly for all Inkjet machines.
The reason is that Printers are Dummy Receivers, meaning that they can not process the print file, sent to them by any source. They are programed to just print the file without "asking questions".
The Manufactures now, of Inkjet machines, in order to avoid the possibility of printing something with a certain colour missing, they have just programmed their machines NOT TO PRINT ANYTHING whenever ANY colour is empty.
So, dont bother trying to print making all kind of adjustments and change settings and get a new cartidge :)
