I-know-what-I mean-so-you-must-do-as-well practice

Sorry Barclays, but you are up again. Just a small thing - but its another one of those 'you wouldn't do something like this offline, so why is it acceptable online?' issues. I had conducted a transaction and wanted to print the page for my records - and the instruction read:-

Yes, I suppose most of use have a print icon to print - but not everyone. 'Use your computer's print facility... ' might be more generic. Oh, and while I think about it, I know what a 'browser' is [I write about e-commerce] my wife does not. She would ask me what the instruction meant. She is far from stupid, she is simply an online newbie.

And in the same vein, this instruction was on another one of their pages:-Again, I know what it means - would every customer? If the answer to this is not 'yes absolutely' then it is not good usability practice.
