Legacy Drivers

drivers/pc-printer-old is a restored legacy printer driver kept for reference. New work should target drivers/pc-printer.

When To Look At It

Use the legacy driver only when:

comparing old behavior during a regression investigation
checking old packaging scripts
recovering behavior that existed before the current BullMQ/Redis driver
understanding old HTTPS setup notes

Main Differences

Area	Current `pc-printer`	Legacy `pc-printer-old`
Queue	Redis-backed BullMQ queues	In-process queue implementation
Persistence	Redis and optional `dump.rdb`	No equivalent durable Redis queue
Packaging	Single `plato-printer.zip`	Full and Lite zip variants
Runtime target	Windows x64 executable	Older full/lite Windows bundles, older README also mentions macOS
HTTPS	Caddy under `assets/caddy`	Older Caddy/certs layout
Current support	Active	Reference only

Legacy Package Scripts

The legacy package includes:

build:full
build:lite
bundle:full
bundle:lite
zip:full
zip:lite

These are not the release path for the current driver.

Do Not Mix Artifacts

Do not copy certificates, Caddy folders, or executables between current and legacy driver folders unless you are deliberately doing a migration test. Their expected folder layouts differ.

Current Driver Path

Use:

drivers/pc-printer
