The barcode type is denoted by k. The following values are valid for k: k Dec Hex Barcode Type 177 B1 178 B2 EAN-13 179 B3 EAN-8 180 B4 CODE 39 181 B5 182 B6 INTERLEAVED 2 of 5 183 B7 UPC-A 184 B8 185 B9 POST-NET (barcode) 186 BA CODE 128 Module width is denoted by m. When m is 1, the barcode prints by 1/360 or 1/240 full dot method. For all other values, the barcode prints by half dot method. The suggested values for m are as follows: m Dec Hex Unit Module Dots Width 24 wire 9 wire 0 00 0.015 in. 0.021 in. 1 01 0.012 in. 0.017 in. 2 02 0.015 in. 0.021 in. 3 03 0.021 in. 0.030 in. 4 04 0.026 in. 0.038 in. The variable s denotes the space width adjustment and affects the barcode printing width. The value for s may range from 3 (03 hex) to -3 (FD hex), however, 0 is the default value. The adjustment unit for 24 wire printers is 1=1/360 in. and for 9 wire printers the unit is 1=1/240 in. The variables v1 and v2 control the bar length. The minimum value of v1, v2 is 288 dec (24 wire) and 270 (9 wire). 62 Section 3: IBM Emulation Mode Printer Commands
