concatenate output of two commands

[asubedi]

How do I concatenate output of two commands? For example, if I do

$ echo "foo" && echo "bar" > tmp

Then foo will be printed in stdout and bar in tmp. I guess I could do

$ echo "foo" > tmp && echo "bar" >> tmp

But what if I want to print to lp?

$ echo "foo" && echo "bar" | lp

will print only bar.

[geirha]

{ echo "foo" && echo "bar"; } | lp

The semicolon at the end of the group must be there, and there must be whitespace after the { and before the }.

[asubedi]

{ echo "foo" && echo "bar"; } | lp

Thanks!
