文件需要盖章，如果没有公章，就用公司抬头纸打印。英语如何说

documents should be sealed by company stamp, if company stamp is not available, please use company letter headed paper.

Files need to be chopped, if not available, pls print the files by papers with your company title.

我建议你去下载个金山词霸翻译软件，那样对你比较方便，但是你不要对它产生依赖哦

Documentations should be stamped, well,the comany paper will be used,if it is inavailable.
