How to know if the fault is in Windows, the network or the printer?

First confirm whether it affects one user or all. Check the physical status and address of the printer, then test connectivity and the computer's website. If other users print, the cause is usually the queue, port, driver, or Windows settings.

Risks to review

  • Delete printers and drivers without registering ports, trays and preferences.
  • Assign a duplicate IP address or change it outside the network plan.
  • Empty shared queues and cancel jobs from other users.
  • Install drivers downloaded from unofficial sites.

Safe recommendations

  1. Determine scope, exact message, user, application and time of failure.
  2. Check paper, consumables, physical errors, network and IP address of the device.
  3. Check if the printer responds from another user or from its web interface.
  4. Check queue, offline status, port and print service.
  5. Use the official driver compatible with the Windows version and architecture.
  6. After fixing, test a Windows page and then the application document.

When to seek specialized help

  • The printer changes address, appears duplicated, or affects the entire headquarters.
  • A print server, network rules, or user authentication exists.
  • The queue stops repeatedly or the driver fails on multiple computers.
