💖 foo2lava — the group chat guide 💖

okay so bestie, listen. this is the manual page for foo2lava, and it lives in the General Commands Manual section 1, which is giving "grown-up command line tool" energy and honestly? it eats. let's get into it. 🫶

✨ NAME ✨

foo2lava — convert Ghostscript pbmraw or bitcmyk format into a LAVAFLOW or a OPL printer stream. yes really. that's the whole job. slay. 💅

🌈 SYNOPSIS 🌈

foo2lava [options] <pbmraw-file >lava-file

foo2lava [options] <bitcmyk-file >lava-file

foo2lava [options] <pksmraw-file >lava-file

three whole ways to feed it, bestie. it reads from stdin, it writes to stdout, it's literally that simple. 🦋

🌸 DESCRIPTION 🌸

okay so foo2lava takes Ghostscript pbmraw, bitcmyk, or pksmraw output formats and turns them into monochrome or color LAVAFLOW or OPL streams. why, you ask? so you can drive:

  • the Konica Minolta magicolor 2530 DL network color laser printer 👑
  • the Konica Minolta magicolor 2480/2480 MF AIO printer
  • and honestly, other Zenographics-based LAVAFLOW printers too, iykyk ✨

it's giving "glue code that just works." periodt.

  • -d duplex — duplex code to send to printer [1].
    • 1 — off
    • 2 — long edge
    • 3 — short edge
  • -g xpixxypix — set page dimensions in pixels [10200x6600]. big page energy.

    • 1 — Tray 1
    • 4 — Tray 2
    • 255 — auto

🧚 Printer Tweaking Options 🧚

these are the options used to customize the operation of foo2lava for a particular printer. this is the "make it fit your machine" section. 🫶

  • -u xoffxyoff — set the offset of the start of the printable region from the upper left corner, in pixels [0x0].
  • -l xoffxyoff — set the offset of the end of the printable region from the lower right corner, in pixels [0x0].
  • -L mask — send logical clipping amounts implied by -u/-l in the LAVAFLOW stream [3].
    • 0 — don't send any logical clipping amounts
    • 1 — only send Y clipping amount
    • 2 — only send X clipping amount
    • 3 — send both X and Y clipping amounts
  • -A — AllIsBlack: convert C=1,M=1,Y=1 to just K=1. works with bitcmyk input only.
  • -B — BlackClears: K=1 forces C,M,Y to 0. works with bitcmyk input only.
  • -z model — Model. the default is [0].
    • 0 — protocol LAVAFLOW — magicolor 2490 MF
    • 0 — protocol LAVAFLOW — magicolor 2530 DL
    • 1 — protocol OPL — magicolor 2480 MF
    • 2 — protocol LAVAFLOW — magicolor 1600W
    • 2 — protocol LAVAFLOW — magicolor 1680MF

🔍 Debugging Options 🔍

these options are used for debugging foo2lava. detective mode: activated. 🕵️

  • -S plane — output just a single color plane from a color print and print it on the black plane. the default is to output all color planes.
    • 1 — Cyan
    • 2 — Magenta
    • 3 — Yellow
    • 4 — Black
  • -D level — set Debug level [0].

⭐ EXAMPLES ⭐

create a black and white LAVAFLOW stream:

gs -q -dBATCH -dSAFER -dQUIET -dNOPAUSE
    -sPAPERSIZE=letter -r1200x600 -sDEVICE=pbmraw
    -sOutputFile=- - < testpage.ps
| foo2lava -r1200x600 -g10200x6600 -p1 >testpage.zm

create a color LAVAFLOW stream:

gs -q -dBATCH -dSAFER -dQUIET -dNOPAUSE
    -sPAPERSIZE=letter -g10200x6600 -r1200x600 -sDEVICE=bitcmyk
    -sOutputFile=- - < testpage.ps
| foo2lava -r1200x600 -g10200x6600 -p1 >testpage.zc

see how it's literally the same pipeline both times? the only glow-up is -sDEVICE=pbmraw versus -sDEVICE=bitcmyk, and the output file going to testpage.zm versus testpage.zc. chef's kiss. 👑
