How do I read the date code (I believe it's a date code?) and is that manufactured date or expiry date?    Thanks 
What's the difference? I changed the page size and trype directly on the printer to see but on the driver it didn't change. Are both required. I have a PIXMA MX 492 on Windows 10.
How much ML of ink does a PG-245XL contain?
I find the solution to this for printing, print odd page numbers on one then flip them round and printer the uneven pages. But what about scanning or copying, is there a way to easily manual duplex? I have a PIXMA 492 printer.
