# Internet Printing Protocol \(IPP\)

Die **Internet Printing Protocol (IPP)**, soos gespesifiseer in **RFC2910** en **RFC2911**, dien as 'n grondslag vir drukwerk oor die internet. Die vermoë om uitgebrei te word, word getoon deur ontwikkelings soos **IPP Everywhere**, wat daarop gemik is om mobiele en wolkdrukwerk te standaardiseer, en die bekendstelling van uitbreidings vir **3D druk**.

Deur gebruik te maak van die **HTTP** protokol, voordeel IPP uit gevestigde sekuriteitspraktyke insluitend **basiese/digeste outentisering** en **SSL/TLS versleuteling**. Aksies soos die indien van 'n druktaak of die navraag van drukkerstatus word uitgevoer deur middel van **HTTP POST versoeke** wat gerig is aan die IPP bediener, wat op **poort 631/tcp** werk.

'n Bekende implementering van IPP is **CUPS**, 'n oopbron-drukstelsel wat algemeen voorkom in verskeie Linux verspreidings en OS X. Ten spyte van sy nut, kan IPP, soortgelyk aan LPD, uitgebuit word om kwaadwillige inhoud deur **PostScript** of **PJL lêers** oor te dra, wat 'n potensiële sekuriteitsrisiko beklemtoon.
```python
# Example of sending an IPP request using Python
import requests

url = "http://printer.example.com:631/ipp/print"
headers = {"Content-Type": "application/ipp"}
data = b"..."  # IPP request data goes here

response = requests.post(url, headers=headers, data=data, verify=True)
print(response.status_code)
```
