💖 zjsdecode — bestie edition 💖

okay so this is zjsdecode(1), a lil command from the General Commands Manual section (section 1, the classics), and it's here to do exactly one iconic thing: turn a ZjStream into human readable form. no cap.

✨ NAME ✨

zjsdecode — Decode a ZjStream into human readable form.

like. that's the whole job. she decodes. she's a decoder. slay.

🌸 SYNOPSIS 🌸

zjsdecode [options] <zjs-file

yes bestie, that < is doing real work there — the file comes in on standard input, not as an argument. pipe it, redirect it, feed it to her, she's hungry 🍓

🦋 DESCRIPTION 🦋

zjsdecode decodes a ZjStream into human readable form. that's it, that's the mission statement, and honestly? she ate.

so what even is a ZjStream? it's a printer language — the vibe some Minolta/QMS and HP printers speak, like the 2300DL and the LJ-1000. your printer is literally out here with its own dialect and this tool is your translator 💅

if you wanna go deeper on Zenographics ZjStream, the lore lives here:

go read it, i'll wait 🧚

👑 COMMAND LINE OPTIONS 👑

these are the options that can appear on the command line. choose your fighter:

  • -d basename — basename of .pbm file for saving decompressed planes. giving "keep the pretty version" energy.
  • -r basename — basename of .jbg file for saving raw planes. the raw, unfiltered, no-makeup truth 🙈
  • -h — print hex file offsets. hex girlies rise 🌈
  • -o — print file offsets. just the offsets, plain, no hex.
  • -p — don't do 4 byte padding. she's taking the padding OUT. periodt.
  • -D level — set debug level, default is [0]. crank it up if you wanna see everything she's thinking.
