OkiML6300 0.14 -- 17.8.2026
WHAT IT IS
A dedicated AmigaOS printer driver for the OKI Microline 6300 (ML6300FB-SC),
the 24-pin flatbed dot-matrix printer, driving its Epson-LQ emulation.
AmigaOS already prints to this machine through its generic Epson drivers, but
the generic path cannot reach the printer's own features. This driver can:
Text all eleven letter-quality typefaces the ML6300 actually has,
verified on paper, plus the OKI-only 15 and 20 CPI pitches and
double-height printing, which the standard Amiga printer command
set has no code for at all.
Graphics 24-pin bit-image dumps up to 360 x 360 dpi -- the highest
densities print each band twice with a half-dot paper feed
between the passes.
Text and graphics were both verified byte for byte against captures of the
data on the wire, and then on paper on the printer itself.
Select OKI_ML6300 in Prefs/Printer like any other driver and print as usual.
The package also includes the "OKIPrinter" preferences editor for SYS:Prefs.
It sets the OKI-only text defaults the standard Printer preferences cannot
express -- typeface, 15/20 CPI pitch and the text styles -- for plain PRT:
output, shows the resolution the printer really uses for the PrinterGfx
density, and prints test pages. An application's own commands always override
these defaults, so programs stay in control of their own output.
WHAT YOU NEED
The printer, on the parallel or serial port, switched to its EPSON LQ
emulation (its factory default).
The ML6300 also has a USB socket, and the driver does not care which
interface carries its output -- but AmigaOS has no USB support of its own, so
that route needs a USB stack (on 68k, Poseidon and its printer class, which
presents the printer as a device such as usbparallel.device). Parallel is the
straightforward connection and the one the driver was developed on.
The driver is an ordinary printer.device driver written to render-interface
level 35, so by design it loads on Kickstart 1.3 (V34) and later; in practice
it has been tested on AmigaOS 3.x, and 2.04 (V37) or newer is the safe
choice. It needs no AGA, no extra RAM and no special hardware.
The preferences editor is a ReAction program and needs AmigaOS 3.0 plus the
ReAction classes V44+ (as supplied with AmigaOS 3.2, 3.5 and 3.9, or with
ClassAct on 3.0/3.1). Its pop-up help bubbles want window.class V47 (3.2).
The editor is optional -- the driver prints without it.
Other OKI 24-pin Microline models with a co-resident Epson-LQ emulation may
work once switched to it; the flatbed ML390FB is the closest relative.
Reports welcome.
WHAT IS IN THE ARCHIVE
Install Installer script for AmigaOS 2.x/3.x
Files/ the driver and the preferences editor
Docs/ the AmigaGuide manual, in English and German
Icons/ the icons, in a classic 4-colour and a GlowIcon set
Catalogs/ the German message catalog for the editor
LICENSE the licence, in full
One build of each program is supplied; there are no processor-specific
versions to choose between.
INSTALLATION
Double-click the Install icon. The installer copies the driver into
DEVS:Printers and installs the editor into SYS:Prefs -- or, if you decline
that, into an OkiPrefs drawer it creates in a drawer of your choosing. It also
asks which icon set you want and which manual languages to install, and offers
the German catalog.
Then open Prefs/Printer, choose OKI_ML6300 as the printer type, set the port
and paper, and Save.
CREDITS
The colour GlowIcons -- the "OKIPrinter" program icon and its drawer icon --

They carry the classic 4-colour images in the same files, so they look right
on older systems too.
