如何打印位图像TM-T88V [英] How print bit Image TM-T88V

问题描述

大家好我有下一个问题我无法打印我的位图，每24行没有白线。即我需要打印图像，但这个图像每24行到位有白线。

hi guys i have the next problem i can't print my bit image without white line each 24 lines. ie i need to print a image but this image have white lines each 24 lines to bits.

epson打印机将图像打印成下一种格式。

the epson printer print the image to the next format.

>line 23 01010101000010001010
>line 24 00001000100000000110
>line 25 --------- white line ------------

如何删除这条该死的白线？

how can delete this damn white line?

    Image size
    width:400px
    height:73px

    while (offset < height) 
    {
    //format ESC* Epson printer
    String modIMG = new String(new byte[]{0x1B, 0x2A, 33, 0, 2});
        img.append(modIMG);     
            for (int x = 0; x < width; ++x) {
                for (int k = 0; k < 3; ++k) {
                byte slice= 0;
                    for (int b = 0; b < 8; ++b) {
                    int y = (((offset / 8) + k) * 8) + b;
                    int i = (y * width) + x;
                    boolean v = false;
                        if (i < bitSet.length()) {
                            v = bitSet.get(i);}
                            slice |= (byte) ((v ? 1 : 0) << (7 - b));
                        }   
                        img.slice(new String(new byte[] {slice}));
                    }
                }
                offset += 24;
                img.append(new String(new String(new byte[]{0x1B,0x33,30}));
                }

谢谢并提前！

推荐答案

我解决了它设置页面模式跟随Marc Balmer的例如，但必须发送24 * 2点（线高双倍密度）的Feed才能使其正常工作：所以在每一片数据后发送命令 ESC J n bytes {27,74,48} 。终于搞定了！

I solved it setting page mode followin Marc Balmer's example, but have to send feed for 24*2 dots (line height double density) to get it working: So after every slice of data send command ESC J n bytes {27, 74, 48}. And finally got it!
