ppm stands for Portable Pixmap among others like Page Per Minute or Perl Package Manager or ...
But I need a pdf from some scanned images.
Some searching through Synaptic Package Manager on keys like 2pdf and todpf
Unfortunately gscan2pdf has a GUI but it works. So fireup gscan2pdf, add some images, and click the 'pdf' button.
