Backspace of one character
Function:
After each BS character (backspace) the print head is moved logically one cha-
racter to the left. Thus characters can be printed one upon the other.
If this command is received immediately following graphicspr inting,the print
head will return to the position in which it was before the start of graphics prin-
ting.
In the following cases the BS command is ignored:
– the print head is at the left edge
– the previous character is an HT character (horizontal tab as column limit)
– a command for an absolute or relative point positioning of the print head was
received beforehand (ESC $ (n1) (n2) or ESC \ (n1) (n2))
–withESCa ( n) a textadjus tment otherthan flush left was selected (i. e. cen-
tered, flush right or margin justification).
Example:
With BS the mathematicals ignsfor ’corresponds to’ and ’unequal’ are to be produ-
ced.
Result:
