Overscore and underline characters don’t print in the space betweenthe two positions.Parameters Ln and H nThese parameters set the amount and direction of the movement. To determine their value, firstdecide the distance you want to move the text or graphics, in dots, based on 120 dots per inch.If you want to move to the right, multiply the distance by 120 dpi, then divide the result by256. Assign the whole number result to Hn and the remainder to L n . For example, to move 3" tothe right: (3 x 120)/256 = 1 with a remainder of 104, so Hn = 1 and L n = 104.If you want to move to the left, multiply the distance you wish to move by 120 dpi, thensubtract the result from 65536. Take that value and divide it by 256: assign the whole numberresult to Hn and the remainder to L n . For example, to move 3" to the left:3 x 120 = 36065536 - 360 = 6517665176/256 = 254 (Hn ), with a remainder of 152 (L n )
