1394 Printer Working Group — 00:50:29 (MA-L)
Summary
- // what this is
- 1394 Printer Working Group is registered to MAC prefix
00:50:29in the IEEE OUI database. When a device's MAC address begins with00:50:29, that block was registered by 1394 Printer Working Group — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- 00:50:29 identifies a mid-to-late-1990s IEEE-1394 printing standards working group, not a retail device brand; if seen at all, expect it on period reference/demonstration hardware built to validate 1394 printing specs rather than on mass-market printers.
About this vendor.
A MAC address beginning with 00:50:29 is registered to the 1394 Printer Working Group, a chartered IEEE-1394 ("FireWire") printing standards body — not a commercial device manufacturer — so this prefix does not map to a retail product line the way a typical vendor OUI does.
The group operated as a project of the Printer Working Group (PWG) under the IEEE-ISTO umbrella. Its charter, dated April 3, 1997, states its purpose as "Standardization of the 1394 printing model(s)," covering device discovery and communication specifications for printers and imaging devices on IEEE Std. 1394-1995 links. Named officers were Chair Greg LeClair (Epson), Secretary Larry Stein, and Editor Alan Berkema.
The group's own site credits contributors from Epson and Kodak, both period printer/imaging vendors, which corroborates it as an active mid-to-late-1990s industry consortium rather than a shell registration. However, its pages are frozen with content dated 1997-2000 and a last-modified stamp of November 2001, with no evidence of activity since — the effort appears historical and inactive, and IEEE 1394 printing never displaced USB as the dominant peripheral interface.
Whether 00:50:29 actually shipped on production hardware, versus reference or demonstration devices built to validate the group's own specifications, could not be verified from any source found. No CVE, advisory, or incident tied to this registrant or prefix was found as of an August 2026 search.

- Security history
- no CVE, advisory, or incident tied to this registrant or the 00:50:29 prefix as of an August 2026 search; general FireWire kernel-driver CVEs (e.g. CVE-2023-3159, CVE-2024-27401) are protocol-level and unrelated to this specific OUI[Confirmed] — https://www.mayhem.security/blog/finding-firewire-ieee-1394-vulnerabilities-cve-2023-3159-and-cve-2024-27401
- Related but distinct registrants
- IEEE 1394c (00:19:0D) and 1394 Trade Association (00:A0:2D) hold separate OUI assignments and are not counted as additional prefixes for this vendor [Confirmed] — the IEEE MA-L registry
- Shared-base check
- 00:50:29 is a standard /24 MA-L block registered directly to this registrant, not one of the large IEEE-RA shared bases (e.g. 70:B3:D5, 8C:1F:64); no sub-allocation caveat applies [Confirmed] — the IEEE MA-L registry 005029
- Third-party date artifacts
- maclookup.app's per-prefix page for 00:50:29 returned HTTP 404 during this check; IEEE does not publish an OUI assignment or registration date for any prefix [Confirmed] — direct check, 2026-08
