Many thanks Jayeff but ***I'VE DONE IT!*** Wow. It took me a long time but now both scan and printing facilities work. I went into "SETTINGS" and found that both of these facilities were not available because, for some weird reason, the printer (HP4650) was no longer my 'DEFAULT' printer. I've no idea what changed it as I have not downloaded anything. Anyway, I changed the printer back to the original, 'default' settings and both facilities now work. Thank you so much for your kindness and expertise in helping me. God bless.
