One way to effectively buffer your print output is to open a filehandle directly to a scalar variable, then select the filehandle. Then you can print to STDOUT at a later time. This allows you to avoid modifying your sub. The following snippet is UNTESTED: 
my $out;
open my $fh, '>', \$out or die "cant open variable\n";
select $fh;
print1('foo');

# do some stuff

print STDOUT $out;
