41.the wheel does not turn and printer only prints a heavy line

轮不转，打印机只能打出一条粗线。

So long as after that loop, I print out a new line over here.

只要在循环之后，我在这里打印出一行新的。

Sometimes different spellings were used for purely practical reasons, such as adding or omitting letters merely to help the layout or justification of printed lines.

有时纯粹出于实用原因使用不同的拼写， 例如添加或省略字母只是为了帮助排版或印刷行的对齐。
