8、可在每一行商品下加入折扣行，折扣行商品名称栏填写”折扣（X.XXX）”字样，其中“X”为折扣率数字，金额和税额栏以负数填写，税率与发票税率相同，其它栏不填写。对于相邻商品行折扣率相同的，可汇总填写折扣行，折扣行商品名称栏填写”折扣行数Y（X.XXX）”字样，其中“Y”为汇总行数数字，汇总金额和汇总税额栏以负数填写，税率与发票税率相同，其它栏不填写。3、销货清单当发票明细行数超过发票打印行数（现行发票的打印行数为8）时，系统将开具销货清单，销货清单的汇总金额和税额填写在发票上，如果包含折扣，则清单和发票都要包含原价汇总行和折扣汇总行。各汇总行由系统自动产生，无需外部传入。4、价格方式对于各商品行
9、，发票票面上必须打印不含税单价和不含税金额，但传入单价可以为含税单价，系统自动转化为不含税单价和金额，并按含税单价计算含税金额，此时，无论传入单价数据如何精确，价格方式不同都可能产生不同的金额和税额。六、调用方式举例下面仅以C+建立语言为例分几种情况作一举例：程序要实现的流程如下：首先要创建组件实例金税，然后调用opencard()方法打开金税卡，如果成功打开金税卡了，这时就可以传入开票数据了（传入发票整体信息前调用invinfoinit（）方法初始化发票整体信息各项属性。）。记住：开票完毕时，要关闭金税卡，释放对金税卡的设备占用，释放其他占用的资源。新tgoldtax金税=（本）；openc
10、ard()金税-；.此处添加调用组件方法实现各项功能的具体代码.closecard()金税-；删除金税；以下各例均已假设已实现组件实例金税，并且金税卡已成功打开，使用完毕也已释放其占用的资源的。此处我们只是为了说明如何调用其各项功能，并没有详细的考虑各方法实际的返回情况，我们假设返回都成功。实际使用中可能因多方原因，实际返回与此有异，但请参照上面接口功能中各方法的返回状态retcode。生成发票的情况1、负数发票按照税务总局新规定，开具负数发票，必须在备注首行中注明”对应正数发票代码xxxxxxxxxx号码yyyyyyyy”字样，Where X is the upper left of the
