ABAP - BARCODE Printing In Smartforms

BARCODE Printing

The "new bar code technology" described here requires definitions in the list of system bar codes in Transaction SE73 exclusively. Those bar code definitions are device-independent and therefore do not require any changes or enhancements of device types / print controls nor any maintenance of printer bar codes as this was the case with the "old" printer-based bar code output (Note 5196).

The text follows:
After creating a new system bar code in SE73, we can print this bar code via SmartForms using any suitable SAP device type. The following device types are suitable:
- All PCL5 device types (e.g. BRHL, CAN105, HPLJ8000, LEXT622, OKI6100)
- All PostScript device types (e.g. POSTSCPT, POST2)
- All Kyocera PRESCRIBE device types (e.g. KYOFS150, KYOFS170)
- All device types for Windows printing via SAPlpd (e.g. SAPWIN, SWIN, I2SWIN, JPSAPWIN, CNSAPWIN)

Solution
Note on the proceeding: The "new bar code technology" described here requires definitions in the list of system bar codes in Transaction SE73 exclusively. Those bar code definitions are device-independent and therefore do not require any changes or enhancements of device types / print controls nor any maintenance of printer bar codes as this was the case with the "old" printer-based bar code output (Note 5196).
After creating a new system bar code in SE73, we can print this bar code via SmartForms using any suitable SAP device type. The following device types are suitable:
- All PCL5 device types (e.g. BRHL, CAN105, HPLJ8000, LEXT622, OKI6100)
- All PostScript device types (e.g. POSTSCPT, POST2)
- All Kyocera PRESCRIBE device types (e.g. KYOFS150, KYOFS170)
- All device types for Windows printing via SAPlpd (e.g. SAPWIN, SWIN, I2SWIN, JPSAPWIN, CNSAPWIN)
If we create a new system bar code for the "new bar code technology" in Transaction SE73, we must specify the following parameters:
? Bar code name (used in Smart Styles)
? Short text for system bar code (documentation)
? Bar code symbology:
? Code39
? Code128
? Interleaved 2of5
? PDF417
? Code93
? ? This selection determines the technical bar code type that is used to format the bar code data (also called bar code symbology).The symbology also determines which characters are allowed in the bar code data.
? Bar code alignment:
? Normal (that is, the scan direction is "from left to right")
? Rotated (the scan direction is rotated by 90 degrees "from top tobottom")
? Inverted (the scan direction is rotated by 180 degrees "from right to left")
? Bottom-up (the scan direction is rotated by 270 degrees "from bottom to top")
The other parameters are determined by the selected bar code symbology.
****************** Code39 ****************
Code39 is an alphanumeric code that can represent the following characters in the bar code data:
Numbers: 1234567890
Capital letters: ABCDEFGHIJKLMNOPQRSTUVWXYZ
Special characters: - . $ / + %
Blank characters (space characters)
The start and stop character for the Code39 bar code is usually represented by an asterix in the text view of the bar code data (also called "human-readable text" or "interpretation line").
Parameters for Code39:
? Narrow module width
? Value range: 1 to 10
? This is the width for the narrowest module of a bar code, measured in pixels. It controls the width of the bar code.Value 1 generates the "narrowest", value 10 the widest bars or spaces.
? Linear height
? Value range: 1 to 9999
? Controls the height of the bars of the bar code, measured in pixels.A value of 600 is equal to a height of one inch.
? Mod-43 check digit
? Value range: X equals YES, blank character equals No
? With this indicator, we can determine if a Modulo-43 check digit is to be generated.
? Bar ratio
? Value range: 20 to 30
? This value controls the ratio between wide and narrow bars.Value 20 means a ratio of 2.0:1, value 30 means a ratio of 3.0 to 1 (that is, 3:1).
************* Interleaved 2of5 ***********
Interleaved 2of5 is a numeric code that can only represent the digits 0 to 9. As digits are always represented in pairs in the bar code, the total number of digits must always be even.If the number of digits (including an optional check digit) is uneven, the system adds a leading zero to the bar code data automatically.
Parameters for Interleaved 2of5:
? Narrow module width
? Value range: 1 to 10
? This is the width for the narrowest module of a bar code, measured in pixels. It controls the width of the bar code.Value 1 generates the "narrowest", value 10 the widest bars or spaces.
? Linear height
? Value range: 1 to 9999
? Controls the height of the bars of the bar code, measured in pixels.A value of 600 is equal to a height of one inch.
? Mod-10 check digit
? Value range: X equals YES, blank character equals No
? With this indicator, we can determine if a Modulo-10 check digit is to be generated.
? Bar ratio
? Value range: 20 to 30
? This value controls the ratio between wide and narrow bars.Value 20 means a ratio of 2.0:1, value 30 means a ratio of 3.0 to 1 (that is, 3:1).
***************** Code 128 ***************
Code128 is an alphanumeric code that can encode three different character sets.Each of the three character sets can represent 106 different characters. Within a bar code, we can alternate between the character sets.
The three Code128 character sets are called as follows:
? Subset A) (contains, for example, digits, capital letters and control characters)
? Subset B) (contains, for example, digits, capital and small letter)
? Subset C) (digit pairs from 00 to 99)
The following shows a table of the three character sets and the encoded characters:

Parameters for Code128:
? Narrow module width
? Value range: 1 to 10
? This is the width for the narrowest module of a bar code, measured in pixels. It controls the width of the bar code.Value 1 generates the "narrowest", value 10 the widest bars or spaces.
? Linear height
? Value range: 1 to 9999
? Controls the height of the bars of the bar code, measured in pixels.A value of 600 is equal to a height of one inch.
? Code128 mode
? Value range: N (default value), A, U
? In default mode N (None), the Code128 bar code works in subset B. If we want to switch to another subset, we must trigger the change explicitly with a control command ("invocation code") in the bar code data.
? In mode A (automatic), the software analyzes the transferred bar code data and recognizes automatically which subset is the most adequate for the bar code data. Subsets are swapped automatically in the bar code data.A sequence of four or more digits initiates an automatic change in subset C.
? In mode U (UCC case mode), we must transfer 19 digits in the bar code data.Subset C is set automatically and an FNC1 character is added as prefix.
? +Remark:+If less than 19 numbers are transferred, the bar code data are filled with zeros to the left until it contains 19 digits.
? UCC check digit
? Value range: X equals YES, blank character equals No
? Note: This parameter has no function since Code128 always generates a check digit, even in UCC mode. The parameter will be removed in the future.
Invocation codes for Code128 Mode N:
We can select subsets A, B and C in two ways:
1) A special invocation code is added to the bar code data as prefix.
2) At the beginning of the bar code data, a special start code ("start code A", "start code B", "start code C") is used.
To switch the subset within the bar code data, insert an invocation code at the relevant position in the bar code data.The new subset is valid until the subset is changed again with a new invocation code.
Example:In subset C, a ">7" code in the bar code data initiates a change to subset A.
The following table shows the Code128 invocation and start codes for the three subsets:
Invocation Decimal Subset A Subset B Subset C
Code value Character Character Character

> 6 100 CODE B FNC4 CODE B
> 7 101 FNC4 CODE A CODE A
> 8 102 FNC1 FNC1 FNC1
Start Characters:
> 9 103 Start Code A (Numeric Pairs giveAlpha/Numerics)
> : 104 Start Code B (Normal Alpha/Numeric)
> ; 105 Start Code C (All Numeric 00-99)
Code 128 - subset B
Since Code128 subset B is the subset used most frequently, Code128 starts in subset B by default when in mode "N" if a start character is not defined in the bar code data.The bar code data for Code128 is transferred directly as ASCII characters, with the exception of values over 94 (decimal) and some special characters':
^ > ~
These characters must be transferred with the invocation codes listed above (for example, ">0" to represent the greater-than sign (>) in subset B or "><" to represent the caret character (^)). Code128 - subsets A and C Both subsets A and C are represented as digit pairs from 00 to 99 in the bar code data (see above in the table with the three character sets). In subset A, a digit pair represents an individual character within the bar code; in subset C, the digit pair represents exactly the two digits of which it consists. Example for subset A: The bar code data >9515334513752003331
encodes the string "SUBSET A?" in subset A. Bear in mind that subset A is started with the start character ">9" and that each subset A character to be encoded is represented with its decimal code.Therefore, we can also represent non-printable characters and special characters that are "illegal" in SAP Smart Forms with the Code128 bar code.
Example for subset C:
The bar code data
>;1234567890
encode the string "1234567890" in subset C. Bear in mind that subset C is started with the start character ">;".
+Remark:+If we specify anything else but a digit as the first position of a digit pair in the bar code data of subset C, this "illegal" character is ignored.However, if we specify a "non-digit" character in the second position of a digit pair, the entire digit pair is ignored.
***************** Code 93 ***************
Code93 is an alphanumeric code that can represent the following characters directly in the bar code data:
Numbers: 1234567890
Capital letters: ABCDEFGHIJKLMNOPQRSTUVWXYZ
Special characters: - . $ / + %
Blank characters (space characters)
The start and stop characters in the Code93 bar code are represented as # sign in the text view of the bar code data (also called "human-readable text" or "interpretation line").
Representation of the full ASCII character set in Code93:
By combining one of the special characters
' & ( )
with another character, we can represent the complete ASCII character set (that is, all characters from 0 to 127 in decimal form) with Code93 as follows:

Parameters for Code93:
? Narrow module width
? Value range: 1 to 10
? This is the width for the narrowest module of a bar code, measured in pixels. It controls the width of the bar code.Value 1 generates the "narrowest", value 10 the widest bars or spaces.
? Linear height
? Value range: 1 to 9999
? Controls the height of the bars of the bar code, measured in pixels.A value of 600 is equal to a height of one inch.
? Check digit
? Value range: X equals YES, blank character equals No
? Code93 symbology mandates a pair of check characters and the check characters are always generated. This parameter has no function.
***************** PDF417 *****************
PDF417 is a two-dimensional bar code to represent datasets that are larger as the usual datasets in one-dimensional bar codes (for example, more than 1000 characters).
A PDF417 bar code consists of 3 to 90 consecutive rows.Every row consists of a start/stop indicator and "code words".A code word consists of four bars and four spaces.The minimum number of code words per row is three.
Parameters for PDF417:
? Narrow module width
? Value range: 1 to 10
? This is the width for the narrowest module of a bar code, measured in pixels.Value 1 generates the "narrowest", value 10 the widest bars or spaces.
? Linear height
? Value range: 1 to 9999
? This value currently has no effect on PDF417. The height of a PDF417 symbol is controlled by parameter "Single Row Height" and the number of columns and rows, in conjunction with the length of text data to be encoded.
? Single row height
? Value range: 1 to 32000
? This value, multiplied by the narrow module width, returns the height of the individual rows of a PDF417 symbol, measured in pixels. Caution: Do NOT use value 1 for this parameter.
? Security level
? Value range: 0, 1-8
? This parameter controls the number of code words that are generated for error recognition and error correction.The default value 0, however, only permits error recognition but no automatic correction.If we increase the security level, the level of error correction increases with it (this increases the size of the bar code).
? Number of columns
? Here, we can define the number of the code word columns which we can use to check the width of the bar code.
? Value range:
? 0 (default value) : A row/column ratio of 1:2 is used.
? Allowed values: 1 to 30
? Number of rows
? Here, we can define the number of rows which can be used to check the height of the bar code.
? Value range:
? 0 (default value) : A row/column ratio of 1:2 is used.
? Allowed values: 3 to 90
? Example:If we leave both parameters set to the default value 0, the system would convert 72 code words in a bar code symbol with 6 columns and 12 rows.
? Truncation
? Value range: X equals YES, blank character equals No
? This indicator determines if the right row indicator and the stop pattern are to be truncated (this saves space).
? ? Remarks:
? - If we specify values higher than zero for Number of columns and Number of rows, the result of both values must be less than 928.
? - A bar code is not printed if the result of Columns and Rows is higher than 928.
? - A bar code is not printed if the total number of code words is higher than the result of Columns multiplied with Rows.
? - We can use Truncation if it is unlikely that the bar code is damaged.
