ESCP2TOPBM(1)

✨ NAME ✨

escp2topbm — convert an ESC/P2 printer file to a PBM image 💖

---

🎀 SYNOPSIS 🎀

escp2topbm [printfile]

🌸 DESCRIPTION 🌸

okay so first things first, bestie: this is the Escp2topbm User Manual, section 1 of the General Commands Manual, and escp2topbm is part of Netpbm(1) — one of the family, we love to see it 🫶.

So what does it even do? escp2topbm reads an ESC/P2 printer control stream as input. And what does it hand back to you? A PBM image. That's it, that's the whole vibe. 👑

More specifically: escp2topbm filters the raster graphic content out of an Epson ESC/P2 printer control stream and writes the image it would have printed as a standard (raw) PBM image. Like it's reading the printer's mind and screenshotting it, no cap. 😭✨

Where does the input come from? The file named by the printfile argument — or from Standard Input if you don't specify printfile. And the output? Standard Output. Classic. 💅

And the compression tea: escp2topbm understands compression modes 0 (uncompressed) and 1 (RLE compressed) in the Epson input stream. Both of them. Slay. 🔥

💜 OPTIONS 💜

There are, lowkey, no command line options defined specifically for escp2topbm, but it does recognize the options common to all programs based on libnetpbm (See Common Options.) So it's a team player even if it has no special moves of its own. 🌈

• -plain — this is a Netpbm common option, and before Netpbm 10.72 (September 2015) the Netpbm common option -plain has no effect on escp2topbm. So if you're time-traveling back to pre-September-2015 Netpbm, don't expect it to do anything, fr fr. ⏳

🦋 HINTS 🦋

Real talk moment, bestie: as escp2topbm is a simple program, created mainly to test pbmtoescp2, there are some restrictions 👀. Not a flaw, just... the way it is:

• escp2topbm looks only at "ESC." sequences and ignores all data outside these Escape sequences. If it's not in an "ESC." sequence, it is simply not invited to the group chat. 🙈
• escp2topbm assumes that only one raster graphic is in the printer stream. If this isn't true, the result is garbage. Not a metaphor. Actually garbage. 💀
• escp2topbm assumes that all "ESC." sequences use the same width value. If this isn't true, the result is garbage. Again. Truly garbage. 😭

So yeah — one raster graphic, one width value, and everything lives inside the "ESC." sequences. Respect the rules and it eats. Break them and you get nonsense. Periodt. 💅

📜 HISTORY 📜

escp2topbm was added to Netpbm in Release 10.18 (August 2003); it was created around the same time. So it's an OG, basically born and launched in the same era 🎀.
