## [1.0.86] - 2026-06-27
|
||||
|
||||
### 修复
|
||||
- 修复出库单 / 入库单打印时左侧竖线总是画满整页、与单据内容长度不一致的问题：现竖线随内容自动收缩，单据较短或跨页最后一页时只画到最后一行，不再多打一长截。
|
||||
|
||||
## [1.0.85] - 2026-06-27
|
||||
|
||||
### 改进
|
||||
- 出库单 / 入库单打印改为针式打印机友好版式：全部纯黑、去除灰色底纹、表格改纯黑实线边框、字体加粗加大，针打输出更清晰、不再发淡发糊；同时优化列宽，避免单价 / 金额 / 日期等数字被换行截断。
|
||||
|
||||
## [1.0.84] - 2026-06-26
|
||||
|
||||
### 修复
|
||||
- 修复出库单 / 入库单打印时，单据明细超过一页会导致程序卡死无响应的问题（新版打印版式引入的回归）。
