What is a ZLB file?

ZLB files mostly belong to Xerox WorkCentre. ZLB files are used in specialized printing and compression workflows. They exist in two main forms:
  • Printer Files: In some cases, a ZLB file contains printer command data meant for devices such as the Xerox WorkCentre 7800 series. These files may store instructions in a printer language like Zebra Programming Language (ZPL), as used by label design tools such as ZebraDesigner.
  • Compressed Archives: Other ZLB files are built as compressed archives using the zlib compression method. They function similarly to ZIP files, reducing file size for faster transfer and storage. More details on zlib can be found at the zlib website.
  • To open and view a ZLB file, you must decide which form it is:
  • If it is a printer file, use the printer management software provided by your device manufacturer (for example, software for Xerox WorkCentre or ZebraDesigner).
  • If it is a compressed archive, try a decompression tool like 7-Zip or WinZip.

    How to open a ZLB file

    You need a suitable software like Xerox WorkCentre to open a ZLB file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your ZLB file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a ZLB file directly in the browser:. Just drag the file onto this browser window and drop it.

    How to solve problems with ZLB files

    • Associate the ZLB file extension with the correct application.
    • Update your software that should actually open compressed archives. Because only the current version supports the latest ZLB file format. Search, therefore, e.g. on the manufacturer website after an available Xerox WorkCentre update.
    • To make sure that your ZLB file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
