# 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.
