CUPS Consulting

CUPS remains the standard printing system on virtually every modern Linux distribution and is still heavily used in macOS environments. Zwiegnet helps organizations get the most out of CUPS — whether you’re consolidating print servers, integrating authentication, fixing chronic driver or queue problems, or building a resilient multi-site print infrastructure.

We work with pure Linux environments, mixed Linux/macOS shops, and organizations that need reliable, secure printing integrated with LDAP, Kerberos, or Active Directory.

Our CUPS services include:

• Print Server Design & Architecture – Centralized or distributed CUPS servers, printer classes, shared vs. private queues, and right-sizing for your environment.
• Queue & Driver Management – Proper PPD selection, driver installation, raw vs. filtered queues, and eliminating the classic “it only works for some users” problems.
• Authentication & Access Control – Integrating CUPS with LDAP, Kerberos/GSSAPI, or Samba/Active Directory so users authenticate cleanly and only see the printers they’re allowed to use.
• High Availability & Failover – Multi-server CUPS setups, load balancing, and seamless failover so printing keeps working when a server goes down.
• Security Hardening – TLS for the CUPS web interface and IPP, restricted sharing, proper ACLs, and reducing the attack surface of print services.
• macOS & Linux Client Integration – Reliable discovery (Bonjour/mDNS, LDAP, or static), printer deployment via MDM or scripts, and consistent behavior across platforms.
• Troubleshooting & Performance – Diagnosing stalled jobs, driver crashes, network printing issues, CUPS error logs, and optimizing for large or high-volume environments.
• Migration & Consolidation – Moving from older print servers, Windows print servers, or scattered desktop printers onto a clean, manageable CUPS infrastructure.
• Monitoring & Ongoing Support – Integration with Nagios/monitoring tools, log analysis, and managed support for production print environments.

Ideal for schools, universities, creative agencies, research labs, law firms, and any organization that still relies on reliable shared printing — especially those running mixed Linux and macOS fleets.
