if从句和主句中都用了与将来事实相反的虚拟语气.
should 在这里是“万一”的意思.
这句话译为：这台打印机的质量不错.在第一年万一坏了,我们将出资修理.

should 表示可能的虚拟假设。
该款打印机质量好。若购买后一年内出现故障，我们将保修。

should在这里翻译成“万一”，表示一种假设。希望能帮到你。

这个是 If 条件句中虚拟语气的用法，表示的是与将来事实相反的情况，结构如下：从句是 if+主语+should+动词原形/were to do, 主句是 主语+would/could/should/might+动词原形，该题是前者，所以选should，没有其他的结构。希望可以帮到你！
