Character Overstrike

Character Overstrike

Character Overstrike

To create special symbols and underline selected portions of your output, one character (maximum) may be printed over another on a character-by- character or line-by-line basis.

A character overstrike is accomplished using either the backspace control code or a carriage return with no line feed. The overstrike print line will be held in the print buffer and will be merged with the next line to form a single printed line with superimposed characters.

Attempting to print more than two characters in any one print location will result in a loss of data integrity. (Only the last two characters received will be retained.)

When the automatic underlining enhancement is used (ESC&dD), the underlined character is not considered an overstrike character. Therefore, if the underlining enhancement was used to underline a character, another character could still be printed over it without risking data loss.

Bar Codes

To print bar codes, escape sequences are sent to the printer specifying the type of code, bar code height, bar code header information, placement information, and bar code data. The following five escape sequences are used for bar code printing:

ESC*z#V Bar Code Selection

This sequence selects the type of bar code to be used in subsequent printing of bar code data. If a number other than those available is selected, the previously selected bar code type will be used. The following table lists the bar code types available and their corresponding value field numbers.
