## DeepAI NSFW scanning
|
||||
|
||||
If you would like to open the service up to public, consider enabling NSFW scanning to prevent naughty content from entering your printer.
|
||||
To enable it, first make a account on [DeepAI](https://deepai.org), then sign up for a DeepAI PRO subscription to use the API (5$ per month), lastly grab the API from your user dashboard
|
||||
`User icon in the top right corner --> View Profile --> API Keys`
|
||||
and put it in your eprintcloned file
|
||||
|
||||
```
|
||||
deepaiapikey=00000000-0000-0000-0000-000000000000 # replace zeros with your actual API key
|
||||
```
|
||||
|
||||
### For this to even work
|
||||
You need a linux distro which has the modern equifelent of the lpr program. To check if you have the newer version, type `man lpr` and look at the program description, if it says `lpr - print files` (present on recent Ubuntu versions and rolling release distros like Arch Linux) then you are good to go otherwaise if it says `lpr - off line print` (present on Debian and older Ubuntu versions) then this won't work as the commands for the older version are different and this targets the newer version of the program.
