Turning Off Deep Sleep on Brother HL2350DW Raw

Because it's annoying as fuck if you set up wireless printing. I'm assuming a PM at Brother thought this would save the planet _and_ get them a promotion 🙄

- Go to **General Setup** -> OK
- Scroll with arrow keys to **Ecology** -> OK
- Scroll with arrow keys to **Sleep Time** -> OK
- Set it to 0 minutes -> OK
- Now you have to hold _both_ the back button and down button to see the 'secret' **Deep Sleep** option. Turn it off and you'll see "Accepted".
- Hit OK the appropriate number of times to get back to the main menu

### Update for macOS

This _still_ does not clear deep sleep _sometimes_. There's apparently a maintenance mode option. I read through their [troubleshooting guide](https://help.brother-usa.com/app/answers/detail/a_id/151825/~/unable-to-print-after-the-machine-has-entered-deep-sleep---windows#Recommeded). Then disabled IPv6 and things _appear_ to work. **Update** It's still shit. Nothing works with this freaking thing, not even the latest firmware update. I had to resort to 👇

### Bash Script for Unifi Controller

👉 This only works if you use Unifi gear. Here's a small `bash` script that 'kicks' the printer every hour or so. This is the equivalent of clicking "Reconnect" from the Unifi Controller UI. Unbelievable. There's a PM at Brother who deserves at least one terrible week.

```bash
#!/bin/bash
