An invalid character was entered. 'nn' is the ASCII value of that character. This error occurs if you include a letter in a bar code that requires numeric data only, such as EAN or 25.

Verify the data for the bar code.

The string you tried to print in the 2 of 5 Interleaved format has an odd number of digits. With the 2 of 5 Interleaved and Code 128C bar codes, digits are paired in groups. Note that if you use the 2 of 5 Interleaved bar code with a checksum calculation, you must send an odd number of digits, as the checksum digit will be rounded to an even number of digits.

Verify the string size, and send an even or odd number of digits.

An invalid length of data was entered for the bar code. This means that the data string is too short or too long.

Verify that the data length conforms to the symbology specifications. (See "Sizing Parameters.")

The Bar Code Printing function found an unexpected value in the UPC-E bar code.

Make sure that there is a minimum of four zeros, and verify that the data conforms to the UPC-E symbology specifications. (See "1D Bar Codes.")

The string supplied to the Bar Code Printing function to generate the French Postal 39 bar code does not start with 'RA' or 'RB'.

Verify that the data for the bar code conforms to the French Postal 39 symbology specifications. (See "1D Bar Codes.")

The Australia Post 4 State 37-CUST bar code encodes the DPID, an eight digit number. The DPID string supplied to the Bar Code Printing function to generate the 37-CUST bar code does not consist of eight digits.

Verify the length of the DPID string. (See "1D Bar Codes.")

The Australia Post 4 State 52-FF-MET and 67-FF-MET bar codes encode the DPID, an eight digit number, and the customer information, which can be encoded using the N table if it only includes digits. Either the DPID string does not consist of eight digits, or there is no customer information defined in the string, or the comma separator is missing.

Verify that the data for the bar code conforms to the symbology specifications. (See "1D Bar Codes.")

The Australia Post 4 State 52-FF-MET and 67-FF-MET bar codes encode the DPID, an eight digit number, and the customer information, which can be encoded using the N table if it only includes digits. The customer information defined in the string supplied to the Bar Code Printing function includes at least one character that is not a digit.

Verify the customer information data for the bar code, and make sure that the data conforms to the symbology specifications. (See "1D Bar Codes.")

The customer information section of the 52-FF-MET and 67-FF-MET bar codes has a defined maximum length depending on the N or C encoding table of the p parameter. The customer information defined in the string supplied to the Bar Code Printing function exceeds its maximum length.

The maximum length is NN based on the encoding table of the p parameter. Make sure the customer information data adheres to this specification.

The customer information section of the 52-FF-MET and 67-FF-MET bar codes includes a predefined set of characters. The customer information defined in the string and supplied to the Bar Code Printing function, includes illegal characters.

Verify the customer information data, and make sure that there are no illegal characters.

The number of rows and columns indicated in the escape sequence do not leave enough room for data encoding.

Increase the size of the columns and rows so that the encoded data fits properly. (See "2D Bar Codes.")
