This command can be used to set up to 16 horizontal tab stops at the intervals of your choice.
The actual distance represented by the tab depends on the character pitch in effect when the
printer receives the HT command.
The tab information must be entered as three-digit ASCII numbers (xyz) separated by commas,
and must be in ascending order. For tabs less than 100, enter a zero for the x and/or y digits as
appropriate.
For example, suppose you wish to set tabs at the 5th, 10th, 15th and 20th columns. The value
for x
1
y
1
z
1
would be 005; the value for x
2
y

z

would be 010, etc. So, you would enter the BASIC
statement
LPRINT CHR$(27);CHR$(09);"005,010,015,020";CHR$(13)

This command can be used to set up to 16 horizontal tab stops at the intervals of your choice.
Setting tabs by dot columns gives you more precise control than setting tabs by character
space.
