# Proposal

## 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.

## 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

## Capabilities

### New Capabilities
- `printserver/cups`: Containerized CUPS print server with AirPrint/IPP sharing and Brother HL-4150CDN driver support

### Modified Capabilities
None

## 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
