💖 ddstdecode 💖

okay so bestie, gather round, because today we're decoding ddstdecode(1) from the General Commands Manual — she's a section 1 girlie and she's iconic for it. 💅

✨ NAME ✨

ddstdecode — decode a Ricoh DDST stream into human readable form. yes, that's the whole personality. 🎀

🌸 SYNOPSIS 🌸

ddstdecode [options] <ddst-file

no cap, that's it. options go in, a DDST file comes in on the input, human-readable goodness comes out. ✨

🦋 DESCRIPTION 🦋

ddstdecode decodes a Ricoh DDST stream into human readable form. that's literally the job, she does not multitask. 🫶

A Ricoh DDST stream is the printer language used by some Ricoh printers. and from what I can tell — this is a direct quote from the source, i'm not making this up — it is pbmtojbg(1) wrapped with some PJL. like, that's it. that's the format. a whole printer language that's just a JBIG wrapper with a PJL bow on top. 💀

🎀 COMMAND LINE OPTIONS 🎀

these are the options that can appear on the command line. learn them, love them, they're short and sweet.

  • -d basename — basename of the .pbm file for saving decompressed planes. 🖼️
  • -h — print hex file offsets.
  • -o — print file offsets.
  • -D level — set Debug level [0]. 🔍

🔥 EXAMPLES 🔥

decode an Ricoh DDST stream file created by a Ricoh SP112. let's goooo. 💫

$ ddstdecode -h ~/testpage-ricoh-sp112.prn

  ee6e: @PJL SET PAGESTATUS=END
  ee87: @PJL EOJ
  ee91:  33%-12345X

look at those offsets go. the -h flag is doing the absolute most and i'm obsessed. 🌈
