Sets the number of lines to be printed on each vertical inch (also called vertical pitch). n specifies the line spacing as follows:

Lines Per Inch:	2	3	4	6	6	8	12
Value of n
ASCII	4	5	6	0	1	2	3
Decimal	52	53	54	48	49	50	51
Hexadecimal	34	35	36	30	31	32	33

6 lines per in. line spacing may also be set using ESC [ z, without sending parameter n.

When the lines per inch setting is changed, the active line moves down after the next vertical paper motion command to the next even multiple of the new vertical pitch. The physical positions of the vertical tabs are also altered. Changing lines per inch does not reset the top or bottom margin.
