Consumer and business devices; official services vary by product and country.
Read the label on your product
Use the label on the main unit, not a separate component, accessory or shipping barcode.
Product NO./P/N is the model or configuration identifier, not the unique serial.
The cartridge number and printer series name are not the device serial.
Single-digit year requires decade context. This is a historic printer format, not the modern HP PC or all-printer format.
Scope matters
Research reviewed October 16, 2026. This independent tool applies published rules and retains unresolved years and model candidates.
Only HP7586B and DesignJet750C(E/AO-size), as documented by HP. Requires matching model and explicit selection of this historic printer format; never infer the format for other HP products.
The year is one digit, so the decade needs independent model/history context. HP gives ESB2A00207 as October 1992. The prose calls the revision character numeric but its own example usesB, so preserve the printed character without asserting it must be numeric. OnlyUS/ES country examples are mapped; other country codes need separate evidence.
Confirm this is the documented HP7586B or DesignJet750C(E/AO-size) historic printer format. It does not apply to modern HP PCs or all printers.
Reading your result
Some systems reuse letters or only encode the last one or two year digits. Every supported interpretation is retained. A decade supplied from reliable records can narrow the reading; the tool does not automatically pick the newest year.
Usually the model is a separate plate field. Where published serial ranges actually identify a model, the result shows model candidates and links to their manuals. Overlapping ranges remain ambiguous.
After a lookup, the address includes the serial in a fragment beginning with #serial=. Use “Copy share link” to share the serial and selected context. Opening the link runs the same lookup. The fragment is not a query-string result page.
