Hand Held Products IT4410 manual 2D Stacked / Multi-row, PDF417, Excessive Print Shrinkage -43% of

While the details are explained below, this general format includes:

•the encoded data (the usual output message) in the first line.

•a banner " >>> PQA from HHP <<<" identifying the start of the 2D PQA report.

•the symbology, its features, and approximate size.

•graded print quality parameters in the following lines.

In the 2D PQA Screening mode with "A" as the Minimum Acceptable Grade, this same scan would be accompanied by a triple beep and the following output message:

This is a representative PDF417 symbol

>>>PQA from HHP <<<

Minimum Acceptable Grade = A PDF417: X roughly = 0.014" Poor Edge Accuracy (59%)

Excessive Print Shrinkage (-43% of X)

With "C" as the Minimum Acceptable Grade, this same scan would produce just a single beep and the following output message:

This is a representative PDF417 symbol

>>>PQA from HHP <<<

Minimum Acceptable Grade = C PDF417: X roughly = 0.014" All Measurements within range

The actual details of the symbol identifying and print quality parameters are explained in the following sections.

2D Stacked / Multi-row

This section describes 2D PQA outputs for PDF417 and MicroPDF417, as well as their derivative 2D arrays used in UCC/EAN Composite Components and T-Linked Code 39.
