[7] "DLV" command parameters
Items
Bar code scanning level
Note 1: The "DLV" command applies to all one-dimensional codes, not to two-dimensional ones.
Note 2: Specifying a high scanning level may increase the scanning time required.
The entry range of the scanning level is from 1 to 8. Increasing the scanning level value decreases the bar-code
reading efficiency, but it diminishes the possibility of misreading of low-quality bar codes (split, stained, thicker, or
thinner). To the contrary, decreasing the value increases the bar-code reading efficiency, but the scanner may misread
low-quality bar codes.
