Printronix T5000e Series user manual Overview

Chapter 1 Overview

•The validator can also evaluate PDF 417 bar codes. For PDF 417 Limited, the validator works best with security level 5 or higher, using the current default printer settings for Defects Percentage, Percent Decode, and Decodeability. For lower security levels, lower the Defects Percentage to 5% to enable checking for bar code damage.

•Stacked, 2D, and vertical (ladder) bar codes are not supported.

•Bar codes must have a minimum x-dimension of 10 mil

(0.010 inch) to be recognized by the full width of the scanning beam. The validator can recognize bar x-dimension as narrow as 6.6 mil (0.0066 inch) for 300 dpi printers, and 10 mil (0.010 inch) for 203 dpi printers. The validator cannot recognize x-dimensions smaller than 6.6 mil (0.0066 inch) or larger than 40 mil (0.040 inch).

Refer to Table 1 for the minimum x-dimension requirements for each printer size of a 300 dpi printer.
