SKU Merge is a template parameter that decides whether one order prints one or multiple tickets:

  • No: every SKU in the order prints its own ticket according to quantity — possibly many tickets;
  • Same: identical SKUs are merged onto one ticket — still possibly multiple tickets;
  • All: one single ticket per order regardless of how many SKUs it contains.

In short: choose All for one ticket per order; choose No or Same for multiple tickets.

Note: with All, product info is bound to the Product Name field — it becomes a combination of name, SKU and quantity, and some SKU-level fields (SKU quantity, SKU amount, etc.) become invalid.
