The number of increments equals n 1 + (n 2 x 255). The maximum value is1632.Set Relative Dot Position Command (Epson) ML320 E/I, ML321 E/I ML520, ML521 ML390 Turbo, ML391 Turbo ML590, ML591Function ASCII Dec HexSet Relative Dot Position ESC \ Ln Hn 27 92 L n Hn 1B 5C Ln HnThis command lets you move the print position very precisely to either the right or the left ofthe current print position. Overscore characters don’t print in the space between the twopositions.For the ML390 Turbo and ML391 Turbo printers, this command will move in incrementsestablished by the Set Unit command (see Chapter 12). The default basic increment ofmovement in the LQ mode is 1/80"; in the Utility mode, 1/120".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, then multiply the distanceby 120 dots per inch. Next, divide the result by 256 Assign the whole number result to Hn andthe remainder to L n .Set Absolute Dot Position Command (Epson) ML320 E/I, ML321 E/I ML320 Turbo, ML321 Turbo ML520, ML521 ML390 Turbo, ML391 Turbo ML590, ML591Function ASCII Dec HexSet Absolute DotPositionESC $ Ln Hn 27 36 L n Hn 1B 24 Ln HnThis command lets you place text or graphics very precisely on the page. It uses the left marginas a reference point, and moves the print position in 1/60" increments.Parameters Ln and H nThese variables determine the amount of movement. To calculate their values, multiply thedistance you wish to move by 60, then divide the result by 256 and assign the whole numberresult to Hn and the remainder to L n .For example:to move the print position over 2":
