# IPPEs
## Reason behind this project
The main reason of this project is decision taken by the CUPS maintainer to [drop support for `PPD` files](https://github.com/OpenPrinting/cups-sharing/issues/4) and now rely on [IPP Everywhere](https://www.pwg.org/ipp/everywhere.html) by default and print a warning when using a `PPD` file:
```console
$ lpadmin -p test -E -v ipp://[REDACTED] -m uld-samsung/Samsung_C48x_Series.ppd
lpadmin: Printer drivers are deprecated and will stop working in a future version of CUPS.
```
For the moment, the printer can be installed with `lpadmin` as shown above and the result can be seen with `lpstat`:
```console
$ lpstat -t | grep -i test
device for test: ipp://[REDACTED]
test accepting requests since sam 01 jui 2023 14:30:38
printer test is idle. enabled since sam 01 jui 2023 14:30:38
```
> __and it works!__ - _which is not the case with the `everywhere` driver is selected..._
But what will happens when the `PPD` files support will be removed? Owners of old printers will have to buy a new one to be able to print their documents??
__HELL NO!!__
That's why I've made this project, to allow end-users to be able to install their old printers without having to pass a complete night to debug everything and finally make it work without really knowing how 😅
## Required tools
In order to be able to run the script or simply debug things by yourself, you will need the following commands:
* `lpstat`
* `lpinfo`
* `lpadmin`
Optionally, if you have `avahi` enabled and want to use it, you will then need these commands:
* `avahi-browse`
* `driverless`
You can install them with the following packages:
* `cups` or `cups-client`
* `avahi-utils` (if using `avahi`)
If you want to see the network packets exchanged between your computer and your printer, you will also need to install the `tcpdump` package.
Here is an example command:
```console
$ sudo tcpdump -Xvni any "port 5353 or port 631 or port 9001"
```
