(The above OCR sample is OCR-A. You must enable the OCR-A font (page 9-
1) in order to read it.)
Reading Multi-Row OCR
The image scanner is capable of decoding multi-row OCR text.
Note: Reading rows longer than sixteen characters is not recommended.
Consider the following example. This example shows serial commands as they
would be entered using QuickView.
Example: You need to read multiple rows of OCR-A data as shown below:
12345678
ABCDEFGH
First, enable the OCR-A font. To read the first row of OCR data, you would
program the following template:
OCRTMP"dddddddd".
This template is the default OCR template. If you wanted to read the second
line of data, you would use the following template:
OCRTMP"llllllll".
To read both lines of OCR at one time, use the variable
r
to indicate the start
of a new row. All the other templating variables for the individual rows work
the same as previously described. For instance, in the above example, you
would use the following template to read both rows:
OCRTMP"ddddddddrllllllll".
To read the three rows below, you would use the template command
"OCRTMP"ddddddddrllllllllrlllldddd".
