PRET is a Python command-line toolkit for printer security testing that connects to devices via network (port 9100) or USB and exploits printer languages like PostScript, PJL, and PCL. It translates UNIX-like commands into printer language instructions, enabling attacks such as print job capture, file system access, memory access, and device manipulation.
Use cases
- test printer security before attackers do
- capture or manipulate print jobs on a network printer
- access a printer's file system and memory
- fuzz printer languages like PostScript, PJL and PCL
- discover printers in a local subnet via SNMP
- cause denial-of-service or physical damage to a printer during authorized testing
When to choose
- you are doing authorized penetration testing of printers
- you need to interact with printers via PostScript, PJL, or PCL
- you want a UNIX-like shell interface for printer attacks
- you need to audit print job retention, credential disclosure, or firmware update vulnerabilities
When to avoid
- you need a general-purpose network vulnerability scanner
- your target devices are not printers or do not speak PostScript/PJL/PCL
- you require a GUI-based security tool
- you need actively maintained Python 3 support, since PRET requires Python 2
