Two digits areencoded: one in the bars and one in the spaces. Ten characters are encoded, each any ASCIIcharacter from 0 to 9 (48 to 57 Dec, 30 to 39 Hex).The sum of the black bars and spaces becomes the maximum width of two characters.Select Interleaved 2 of 5 Bar Code CommandThe command for selecting Interleaved 2 of 5 isESC DLE A m 3 0 n 3 n 4 n5 n 6 n 7 n 8Interleaved 2 of 5 Parameters n3 and n4These parameters set the vertical length of the bars in 6/72", as calculated by the equation(n 3 x 10) + n 4 ] x 6/72"where the total value must be less than or equal to 25.Interleaved 2 of 5 Parameter n5Parameter n 5 is used in combination with parameter n 7 to set the width of one character of theblack bars, as follows:Table 76: IBM/Epson Select Interleaved 2 of 5 Command —Black Bar Width for Parameter n 5, n7 Values (9-Pin Printers)n5 = 1 n5 = 2 n5 = 3 n5 = 4 n5 = 5 n5 = 6 n5 = 7n7 = 1n7 = 2n7 = 3n7 = 4n7 = 5n7 = 6n7 = 711/144"13/144"15/144"17/144"21/144"23/144"25/144"18/144"20/144"24/144"28/144"32/144"34/144"38/144"25/144"29/144"33/144"37/144"43/144"47/144"51/144"32/144"36/144"42/144"48/144"54/144"58/144"64/144"39/144"45/144"51/144"57/144"65/144"71/144"77/144"46/144"52/144"60/144"68/144"76/144"82/144"90/144"53/144"61/144"69/144"77/144"87/144"95/144"103/144"
