Notes on the use of PDF-417
Use PDF-417 the same as any other bar code:
1. After entering Easy Print using ESC+EZ, select the barcode using the name “PD417”
2. Enter data between two ‘|’. If the data is long, DO NOT put CR/LF in data unless
you want the CR/LF to be in the bar code
PDF-417 has several field parameters that may be specified:
1. COLUMNS will specify the number of columns of DATA printed in each row of the
bar code. If not specified, the default value of 2 DATA columns is used. The actual
COLUMNS used is 4 greater then DATA COLUMNS. (2 for GARD COLUMNS
and 2 for ROW indicator COLUMNS).
2. SECURITY specifies the level of error detection and correction codes, from 1
through 8. If not specified, the default value for the number of data characters to be
printed is used:
1-40 characters level 2
40-160 characters level 3
161-320 characters level 4
321-863 characters level 5
3. YDIM specifies the height of each element, in units of .005 inches. Default is 1
4. WDIM specifies the width of each element, in units of .005 inches. Default is 1
PDF-417 symbols contains:
1. A maximum of 1848 text characters (fewer if mixed with arbitrary bytes)
2. A minimum of 3 rows and a maximum of 30 rows
3. A minimum of 1 column and a maximum of 30 columns
4. Error detection and correction characters vary with different security levels:
Level 1 adds 4 codewords
Level 2 adds 8 codewords
Level 3 adds 16 codewords
Level 4 adds 32 codewords
Level 5 adds 64 codewords
Level 6 adds 128 codewords
Level 7 adds 256 codewords
Level 8 adds 512 codewords
EXAMPLE:
{PRINT:
@75,10:PD417,YDIM 6,XDIM 2,COLUMNS 2, SECURITY 3|ABCDEFGHIJKL|}
Will print a PDF-417 bar code containing ABCDEFGHIJKL with each element
.010” wide and .030” high, with each row containing 2 data bytes and using a error
detection and correction level of 3, which adds 16 error correction code words to the
bar code.
You can print any characters using the O’Neil PDF-417. It is optimized for the most
common printing of a mixture of numbers, text, and control characters.
