Bar code descriptor for PDF417 Functional parameters for PDF417 (HP compatibility mode) Typeface Esc (s#T Value Default 24850T P parameter 0 Esc(s#P B parameter1 #1 02 Esc(s#1, #2B #2 02 S parameter1 #1 2 Esc(s#1, #2B #2 1 #33 0 Optional; determines ECC level; range is 0-8 Optional; determines number of rows for the symbol; range is 3-90 Optional; determines number of columns for the symbol; range is 1-30 Optional; determines the X-value of the symbol aspect ratio Optional; determines the Y-value of the symbol aspect ratio 0 = Parameters #1 and #2 will equal the size needed for the PDF 417 symbol. (default) 1 = Parameters #1 and #2 can be set to a mandatory size for the PDF417 symbol. #4 0 0 = The PDF417 symbol is not truncated (default) 1 = The PDF 417 symbol is truncated on its right side. 1 The desired size of the symbol may be specified either by using the #b1, #b2 parameters to specify the desired number of rows and columns, or by using the #s1, #s2 parameters to specify the desired aspect ratio. The two techniques should not be used at the same time. If both types of parameters appear in a bar code selection escape sequence, the type appearing last in the sequence is used to select symbol size. 2 Aspect ratio values are used if the #b parameter is not used to manually set rows and columns. 3 The default choice (0) sets the symbol to the necessary size to capture the encoding data. The optional choice (1) uses the values in parameters #1 and #2 to set a mandatory symbol size (larger than necessary for the encoding data), while holding a sparser amount of data. The parameter values sent when using this technique for printing PDF417 symbols will follow the same rules that exist for the corresponding parameters that are sent when using the Transfer Bar Code Descriptor command to print PDF417 symbols. In relation to the fields of the Lexmark bar code descriptor for PDF417, the following correspondences exist when using this technique: ECC Level: Units Enumeration for X Dimension: X Dimension (in X Dimension units): Y Ratio: Truncated: Rows: Columns: Specified by #p parameter Fixed at 2 (600 dpi units) Fixed at 6 Fixed at 3 Specified by #s4 parameter Specified by #b1 parameter Specified by #b2 parameter Two-dimensional bar codes 27
