G'day Tobias,

While it's been a few years since I used it, I found PDF::API2::Simple allowed me to create PDFs quickly with a minimal learning curve.

It aggregates a PDF::API2 object which you can acces via the pdf method. You'll need this for more advanced/complex features such as changing orientation:

$ perl -Mstrict -Mwarnings -E '
    use PDF::API2::Simple;
    my $pdf = PDF::API2::Simple::->new();
    $pdf->pdf->page->rotate(90);
'

Of course, you can dive in at the deep end and use PDF::API2 from the outset.
