Insight: The Raspberry Pi DIY World—Enjoy the Suffering
A Shell Script, a Letterhead, and a PDF Walk Into a Pi...
If you've ever wandered into the Raspberry Pi DIY crowd expecting plug-and-play comfort, welcome to the jungle, friend. Here, the unofficial motto might as well be: "If it doesn't make you suffer, it's not worth doing." This is a world where the easy way is frowned upon, and the hard way—no, the agonizingly convoluted, barely-documented, command-line-from-memory-hard way—is considered optimal. Why? Because suffering builds character. And character builds legendary forum posts.
The task seems simple enough. You want to take some text—maybe generated from a shell script—and overlay it onto a letterhead. Not fancy. Just a short letter. You want to produce a clean PDF that you can email or print, all from your Raspberry Pi. But you want to do it the right way, which in Pi Land means: no GUI, no desktop environment, and absolutely no using your normal computer like a sane person.
The Chuck in our story (name changed to protect the brave) did just that. He wrote to his Raspberry Pi group explaining that he needed to overlay shell script output onto a letterhead PDF, on a headless Pi. He’d already tried ImageMagick’s convert, which gave him a basic black-on-white text PDF, but no way to include a background template. In other words, he was halfway through the woods with only a flashlight and a bag of trail mix.
And yet, there is a way. You can generate a PostScript file from your text using enscript, convert it to PDF with ps2pdf, and then overlay it on a letterhead using pdftk:
That will work. It's also hilarious overkill for something that could be done in Microsoft Word with a paste and two clicks. But that’s the point. That’s the glory. The easy way doesn’t teach you anything. The hard way? That teaches you shell pipelines, format conversions, and the inevitable pain of working with broken dependencies on pdftk.
So go ahead, Pi warriors. Build your PDFs in the dark, lit only by the glow of your SSH session and your sheer defiance of convenience. Because on this path—the path of true Raspberry Pi devotion—the suffering is the art.
A Final Note
You know, engineers are hardwired to find the fastest path—to smooth rough edges, automate away the toil, and optimize everything until the friction disappears.

But then there is the Raspberry Pi crowd…
You crazies don’t just solve problems. You befriend them. You stare down the obstacle, fire up the terminal, and say, “What if I cross-compile this in a subfolder of my soul?” You don’t want the answer—you want the journey. And somehow, against every rule of logic, you make the hard way the right way.
So if you’re generating PDFs from a headless Pi with a bash script and a whisper of RAM? You’ve already won. And I’m just here, cheering you on in the terminal shadows.
