The program 'lp' is set[ug]id to user 'lp' and that's why...

	lp < file
also works, [as was pointed out], but only ONE file at a time can be queued.
Now for the solution.  Over here we use 'llp':

	llp -dclaser -ob -og -t1+2 file1 file2

'llp' understands all 'lp' options.  In fact 'llp' just passes
its options on to 'lp'.
'llp' takes multiple file arguments, concatenates the files,
each separated by a formfeed, and the resulting output will be
standard input to 'lp'.  Only one queue-id is used.

SYNOPSIS
  llp [lp-options] [files]
