-devices can print without installing the Brother driver themselves.
+printer over IPP and advertises it via AirPrint (mDNS/DNS-SD). It prints by
+sending **PostScript (BR-Script3)** straight to the printer, so no vendor driver
+and no 32-bit libraries run in the container.
 
 The container bundles:
 
-- CUPS (IPP/IPP Everywhere + web admin on port 631)
+- CUPS (IPP + web admin on port 631) with cups-filters for format conversion
 - Avahi / DNS-SD for AirPrint discovery (UDP 5353)
-- The Brother HL-4150CDN LPR + CUPS wrapper drivers and 32-bit runtime libs
+- Brother's official HL-4150CDN **BR-Script3 PPD** for device options
+
+## How it works
+
+The HL-4150CDN emulates PCL6 and BR-Script3 (PostScript 3), and accepts
+PostScript over raw AppSocket (port 9100). CUPS converts whatever a client
+sends into PostScript and the BR-Script3 PPD turns the selected queue options
+into PostScript `setpagedevice` instructions:
+
+```
+ macOS / iOS / Windows / Linux              container                    printer
+ ┌─────────────────┐   IPP/AirPrint   ┌──────────────────────────┐   raw   ┌────────────┐
+ │ AirPrint (URF)  │ ───────────────▶ │ CUPS                     │ ──────▶ │ HL-4150CDN │
+ │ PDF / PostScript│                  │  URF/PWG/PDF → PostScript│ :9100   │ BR-Script3 │
+ └─────────────────┘                  │  pstops → setpagedevice  │         └────────────┘
+                                      └──────────────────────────┘
+```
+
+For example, `Duplex=DuplexNoTumble BRPrintQuality=Color InputSlot=Tray2`
+becomes:
+
+```postscript
+<</Duplex true /Tumble false>>setpagedevice
+<</BRProcessColor 4 /BRHrc 0>>setpagedevice
+<</ManualFeed false /BRTraysw false /BRFeeder 1>> setpagedevice
+```

+# BR-Script3 PPD — Brother HL-4150CDN
+
+`BR4150_2.PPD` is Brother's official **BR-Script3** (PostScript 3) PPD for the
+HL-4150CDN.
+
+## Provenance
+
+Extracted from the vendor Windows driver in `../Windows/`:
+
+```
+Y10B_C1-ps-win8-64-103-en.EXE      (ZIP self-extracting archive)
+└── eng/BR4150_2.PPD
+```
+
+```sh
+unzip -j "Y10B_C1-ps-win8-64-103-en.EXE" "eng/BR4150_2.PPD"
+```
+
+The archive also contains PPDs for the related BR4140 and BR4570 models; only
+the HL-4150CDN PPD is used here. Line endings were normalised from CRLF to LF.
+
+## Why this file
+
+The HL-4150CDN emulates PCL6 and BR-Script3 (PostScript 3). This PPD encodes
+every device setting as PostScript `setpagedevice`, for example:
+
+| PPD option | Emitted PostScript |
+| --- | --- |
+| `InputSlot Tray2` | `<</ManualFeed false /BRTraysw false /BRFeeder 1>> setpagedevice` |
+| `InputSlot MPTray` | `<</ManualFeed false /BRTraysw false /BRFeeder 4>> setpagedevice` |
+| `Duplex DuplexNoTumble` | `<</Duplex true /Tumble false>>setpagedevice` |
+| `BRPrintQuality Black` | `<</BRProcessColor 1>>… <</BRRenderMode true>>setpagedevice` |
+| `BRColorMode Normal` | `<</UseCIEColor true>>… <</BRColorMode 0>>setpagedevice` |
+| `BRMediaType Recycled` | `<</MediaType (RECYCLED)>>setpagedevice` |
+
+CUPS's `pstops` filter injects the selected option code, and the PPD's
+`*JCLBegin` / `*JCLToPSInterpreter` / `*JCLEnd` entries wrap the job in PJL.
+
+This lets the HL-4150CDN be driven with a plain PostScript queue, so the
+container does **not** need Brother's 32-bit Linux CUPS wrapper/filter
+(`brlpdwrapperhl4150cdn`) or its Ghostscript rasterisation step.

 ## Context
 
-See proposal.md for motivation - we need to create a Podman container that runs a CUPS print server for Brother HL-4150CDN. The repo contains the Brother driver packages in `assets/Brother HL-4150CDN/`:
-- `lpr-driver/hl4150cdnlpr-1.1.1-5.i386.deb`
-- `cupswrapper/hl4150cdncupswrapper-1.1.1-5.i386.deb`
-- `installer/linux-brprinter-installer-2.2.6-0.gz` (reference only; we will NOT run it in the build - it is interactive and downloads from the network)
+See proposal.md. We need a Podman container that runs CUPS for the Brother
+HL-4150CDN network printer and shares it over IPP/AirPrint.
 
-Key observations:
-- Brother drivers are i386 binaries (32-bit ELF). Container needs 32-bit runtime libraries.
-- CUPS wrapper + LPR packages provide PPD, filters, and helper binaries.
-- AirPrint requires CUPS + Avahi/mDNS (DNS-SD).
-- Brother's cups wrapper installs files to /usr/local/Brother/ and may need symlinks into CUPS directories.
+Facts established while exploring the device at `192.168.100.7`:
+
+- The printer is a Brother HL-4150CDN (`Ver.1.22`) with PCL6 and **BR-Script3
+  (PostScript 3)** emulation — `@PJL INFO CONFIG` lists `POSTSCRIPT`.
+- Open services: `:9100` (raw/AppSocket), `:515` (LPR/LPD), `:631` (IPP/IPPS)
+  and `:80` (Brother web UI). It has one paper cassette plus the MP tray.
+- A raw PostScript job sent to `:9100` is interpreted by the printer, and a full
+  CUPS job with `Duplex=DuplexNoTumble BRPrintQuality=Color` printed correctly
+  (duplex, colour).
+
+An earlier iteration used Brother's Linux packages. That vendor CUPS chain is
+broken in `debian:bookworm-slim`: `filterhl4150cdn` needs `file` (and `a2ps` as
+a fallback), which are absent, so the filter exits 1 and emits zero bytes. That
+chain also rasterises locally (Ghostscript → `ppmraw` → `brhl4150cdnfilter`) and
+stores per-queue options in a single global file (`brhl4150cdnrc`), which is
+heavy and racy. The packages have since been removed from the repository.
+
+Crucially, the Brother **vendor** PPD (`brhl4150cdn.ppd`) cannot be used for
+direct PostScript because its option values are blank (`"          "`); all
+option handling lives in the vendor filter. Brother's **BR-Script3 PPD**, in
+contrast, encodes every option as PostScript `setpagedevice`.
 
 ## Goals / Non-Goals
 
 **Goals:**
-- Create a Containerfile that builds a working image for Podman
-- Install and configure Brother HL-4150CDN drivers
-- Share printer via IPP with AirPrint discovery
-- Expose ports 631 (CUPS/IPP) and 5353/udp (mDNS)
-- Make it easy to run with podman
+- Build a working CUPS image for Podman with no 32-bit dependencies.
+- Drive the printer with its native PostScript (BR-Script3) interpreter.
+- Preserve the hardware options the user cares about: paper tray, duplex and
+  colour/mono (plus the other options the PPD exposes).
+- Share the queue over IPP and advertise it via AirPrint.
+- Keep the printer address/name runtime-configurable.
 
 **Non-Goals:**
-- Managing multiple printers
-- Custom SSL/TLS configuration for CUPS (use defaults or documented)
-- Persistent CUPS spool/state beyond basic setup
+- Managing multiple printers.
+- Sharing via SMB/Samba (Windows uses a client-side Brother driver).
+- Persisting CUPS spool/state beyond the container lifecycle.
+- TLS for the CUPS web interface.
 
 ## Decisions
 
-### Base image
-- Use Debian/Ubuntu (or similar) as base to handle .deb packages and 32-bit libs easily. Alternatively Alpine, but Alpine needs musl + 32-bit support can be more complex for prebuilt i386 ELF binaries from Brother. Debian stable is practical.
+### Base image and packages
+Use `debian:bookworm-slim` with `cups`, `cups-client`, `cups-filters`,
+`avahi-daemon`, `avahi-utils`, `libnss-mdns`, `dbus`, `ghostscript` and
+`poppler-utils`. No `dpkg --add-architecture i386` and no Brother `.deb`
+packages: the job is converted to PostScript in CUPS and interpreted by the
+printer, so no vendor binary is needed.
 
-### Driver installation
-- Use the local `.deb` packages from `assets/Brother HL-4150CDN/` (copied into the build context) and install with `dpkg -i --force-all`. No network download at build time for the driver itself.
-- Do not run the Brother installer script (`linux-brprinter-installer-2.2.6-0.gz`) in the build - it is interactive and downloads packages from download.brother.com.
-- Also need to install brcupsconfpt1 helper if needed - comes with cups wrapper.
-- Run the cups wrapper install logic as per Brother installer (or manually create symlinks).
+_Alternative considered:_ keep Brother's Linux CUPS wrapper + LPR filter. It
+provides the same options but requires 32-bit libraries, Ghostscript
+rasterisation and the missing `file`/`a2ps` tools, and it writes options to a
+single global config file. Rejected.
 
-### CUPS + Avahi + DBus
-- Install cups, avahi-daemon, dbus. Run dbus and avahi-daemon; start cupsd.
-- Configure CUPS to allow remote access/sharing. For containerized setup, typically need to listen on all interfaces and configure sharing.
+### Print path: direct PostScript via the BR-Script3 PPD
+Install Brother's official BR-Script3 PPD as
+`/usr/share/cups/model/BR4150_2.PPD` (committed at
+`assets/Brother HL-4150CDN/ppd/BR4150_2.PPD`, extracted from the vendor Windows
+driver) and create the queue with it. CUPS's `pstops` filter reads the PPD and
+injects the selected option code (e.g. `/BRFeeder`, `/Duplex`,
+`/BRProcessColor`, `/MediaType`) into the job; the PPD's `*JCLBegin`,
+`*JCLToPSInterpreter` and `*JCLEnd` entries wrap it in PJL. The result is
+forwarded unchanged to the printer.
 
-### Printer configuration
-- Add printer via lpadmin using the Brother PPD. Point to network URI (e.g., ipp://PRINTER_IP/ipp or socket://PRINTER_IP:9100 - depends on printer; HL-4150CDN is network printer).
-- Enable printer sharing and default options.
+A stock PostScript PPD (like CUPS's own `generic.ppd`) has no `*cupsFilter`
+either, and CUPS accepts such PPDs — the printer's native format is
+`application/vnd.cups-postscript`.
+
+### Device URI
+Use raw AppSocket as the default: `socket://<ip>:9100`. `lpd://<ip>/binary_p1`
+and `ipp://…` remain available through `PRINTER_PROTOCOL`/`PRINTER_URI`.
+
+### Client support
+- macOS / iOS / iPadOS: AirPrint → CUPS. The queue advertises `image/urf`,
+  `image/pwg-raster`, `application/pdf` and `application/postscript`, with
+  `urf-supported = V1.4,CP1,W8,PQ4,SRGB24,RS600,DM1,FN3`, `sides-supported`
+  (one-sided/two-sided long/short edge) and `color-supported = true`.
+- Linux: IPP / IPP Everywhere, or plain IPP with PDF/PostScript.
+- Windows: client-side Brother BR-Script3 Windows driver, pointed at the
+  printer directly or at the shared queue.
 
 ### Runtime configuration
-- The printer endpoint and advertised name are supplied through environment variables rather than baked into the image, so the same image can be pointed at any HL-4150CDN:
-  - `PRINTER_IP` + `PRINTER_PROTOCOL` (lpd/socket/ipp) derive the device URI.
-  - `PRINTER_URI` overrides the derived URI for full control.
-  - `PRINTER_NAME` sets the CUPS queue name and the DNS-SD/AirPrint advertised name.
-  - `PRINTER_DESCRIPTION` sets the CUPS Description (Info) shown in the web UI.
-- The entrypoint builds the URI and runs lpadmin at startup, then shares the queue.
+The printer endpoint and advertised name come from environment variables
+(`PRINTER_IP`, `PRINTER_PROTOCOL`, `PRINTER_URI`, `PRINTER_NAME`,
+`PRINTER_DESCRIPTION`, `PPD_FILE`) rather than being baked into the image. The
+entrypoint derives the URI and runs `lpadmin` on startup, then shares the queue.
 
 ## Risks / Trade-offs
 
-- [Risk] Brother binaries are 32-bit only → require multiarch libs (libc6:i386, etc.). Increases image size slightly.
-- [Risk] Using .deb packages assumes glibc-based base. If we choose different base, need to ensure compatibility.
-- [Risk] Avahi in container needs --net=host or proper mDNS setup. AirPrint discovery typically works better with host network mode; document this.
-- [Risk] CUPS state (printers.conf, etc.) should be persisted if we want config to survive restarts - may need volumes.
+- [Risk] The AirPrint path (URF → PDF → PostScript) relies on cups-filters'

+  macOS/iOS printing should be verified end to end.
+- [Risk] Colour handling now relies on the printer's PostScript RIP rather than
+  Brother's host-side colour tables; output may differ slightly from the vendor
+  raster driver.
+- [Risk] The committed PPD is a Windows PPD and contains no CUPS-specific keys.
+  CUPS accepts it as a PostScript PPD (verified for this CUPS version), but this
+  should be re-checked on CUPS upgrades.
+- [Risk] Avahi needs host networking (or equivalent) to advertise mDNS.

 ## Why
 
-Provide a Podman container that runs CUPS and shares the Brother HL-4150CDN network printer as an AirPrint and IPP printer. Clients should be able to print without installing local printer drivers.
+Run a Podman container that shares the Brother HL-4150CDN network printer over
+IPP/AirPrint, so clients on macOS, iOS/iPadOS, Linux and Windows can print.
+
+The HL-4150CDN already emulates BR-Script3 (PostScript 3) and accepts PostScript
+on its AppSocket/LPD ports, so the container can forward PostScript directly to
+the printer instead of shipping Brother's 32-bit Linux CUPS wrapper plus
+Ghostscript rasterisation. This removes the i386 dependency, the multiarch
+runtime and the fragile vendor filter chain.
+
+The previous approach (Brother Linux `.deb` packages) turned out not to work in
+`debian:bookworm-slim`: the vendor filter `filterhl4150cdn` needs `file` (with
+`a2ps` as a fallback), which are not installed, so it exits with an error and
+produces no output. The official BR-Script3 PPD avoids that entire code path.
 
 ## What Changes
 
-- Create a Containerfile for Podman (based on a Linux distro that supports CUPS and 32-bit binaries)
-- Extract and install Brother driver files (from `assets/Brother HL-4150CDN/` - local .deb packages: `hl4150cdnlpr` and `hl4150cdncupswrapper`) needed for HL-4150CDN
-- Configure CUPS to run in the container and share the network printer
-- Enable mDNS/Avahi for AirPrint discovery
-- Provide minimal runtime configuration (ports 631, 5353/udp) and documentation for running with podman
-- Handle 32-bit dependencies required by Brother i386 binaries
+- Create a Containerfile for Podman based on Debian stable running CUPS, Avahi
+  and D-Bus (no i386 multiarch).
+- Install Brother's official **BR-Script3 PPD** (committed under
+  `assets/Brother HL-4150CDN/ppd/`) so CUPS emits device options — paper source
+  (tray), duplex and colour/mono, plus media type, print quality, toner save and
+  secure print — as PostScript `setpagedevice`.
+- Point the queue at the printer with a raw AppSocket URI (`socket://<ip>:9100`)
+  by default.
+- Convert incoming client formats (URF/Apple Raster, PWG Raster, PDF, PostScript)
+  to PostScript inside CUPS and pass them through to the printer's PostScript
+  interpreter.
+- Share the queue over IPP and advertise it via mDNS/DNS-SD (Avahi/AirPrint).
+- Keep runtime configuration (printer address, protocol, queue name) in
+  environment variables.
+- Document the supported client matrix.
 
 ## Capabilities
 
 ### New Capabilities

 ## Impact
 
-- New Containerfile (and possibly supporting files) in repository root
-- Uses Brother driver artifacts in `assets/Brother HL-4150CDN/`
-- Runtime ports: CUPS (631), mDNS (5353/udp) for AirPrint
-- Depends on Avahi/DBus, CUPS, and 32-bit compatibility libs for Brother binaries
+- Containerfile plus supporting `cupsd.conf` and `entrypoint.sh` in the

+- Uses `assets/Brother HL-4150CDN/ppd/BR4150_2.PPD`.
+- Runtime ports: CUPS/IPP (631/tcp), mDNS/DNS-SD (5353/udp).
+- No 32-bit runtime libraries; the image no longer depends on the host CPU
+  architecture.
+- Windows clients install Brother's own BR-Script3 Windows driver client-side.
+- The unused Brother Linux `.deb` packages previously under
+  `assets/Brother HL-4150CDN/` have been removed.
