My printer is printing a blank sheet of paper each time (on single sheets).

[LucyB21]

Not having done this before my printer is printing off a blank sheet of paper every time I ask it to print.  This is if I ask it to print 1 page or 10 pages - there is always one extra blank page.

Also it ignores the instruction to print on both sides and prints the document a page at a time (plus a blank page)!

It never used to do this!  Only thing that has changed is I have changed my broadband supplier and have a new router.  The printer would not work at all initially as the router was set at 5GHz but that has been sorted so that it runs at 2.4GHz and hey presto my printer prints wirelessly but as above ignoring a print both sides instruction and spitting out a blank page every time
