Bar Code Symbols and Formats

NOTE

•

UPS MaxiCode expects the secondary message to be padded with a total of 84 fill characters. The

Bar Code Printing function automatically pads the data to the right of the MaxiCode. (The fill

character is '!' ASCII 33, HEX 21.)

•

The secondary message cannot be longer than 84 characters. Therefore, the destination

s address

length must be truncated if the total length of the secondary message is greater than 84 characters.

A destination address is optional in the MaxiCode data. If the MaxiCode data is too long, the Bar

Code Printing function will not print the MaxiCode, and instead prints an error message indicating

how many characters exceeded the maximum length of 84.

•

Blank fields must also include the <Gs> separator.

After the <Eot> character, the application must immediately send a PCL escape sequence to

switch to a font other than MaxiCode.

The following is the escape sequence for switching from MaxiCode to Courier font 10CPI:

<Esc>(s0p10h12vbs4099T

NOTE

If you use a character set other than PC-8, you should resend the character set selection

before selecting the new font.
