Scan deduplication
Scan deduplication runs before labels print: the system checks whether a scan or key field already exists against enterprise data, and can block the job when it is a duplicate—reducing double picks, double labeling, or printing the same document twice. It is separate from “scan once, print labels once” driving logic and is closer to business rules and risk control.
In Luck label software, it depends on a connected enterprise data service, template and connection setup, plus license and roles—not every tenant has it on by default. Use Versions & permissions and delivery docs before go-live. Pair it with Scan to print labels and Print history (after-print trace): one governs whether printing is allowed, the other records what was printed.
What it does
- Timing: validation runs before you commit the print; duplicates can be blocked for that job.
- Dependencies: needs a connected enterprise data service, template and connection setup, plus license and roles—not on by default for everyone.
- Role: business dedup and risk control—not the same step as “scan once to drive print.” Details: Versions & permissions and delivery docs.
Vs. post-print write and print history
- Data write (LuckData): runs after a successful print to push values back to business tables. To block “already exists” before print, use scan deduplication. See Label printing software · Data write.
- Print history: retains trace data after print for reconciliation and audit—different goal and timing. See Print history.
- Print dialog double-submit guard: UI protection during a job—not the same as business dedup.
