范文12：A Report(报告)
To: Director , Center of Equipment Service

From: Director , Exchange Center
Subject: Purchase of a printer
Dear Sir,
Last week, we wrote you a report applying to buy a new printer. This is to remind you of the urgency of our need.
As we said in our last report, there has been a sudden increase in our correspondences with foreign colleges and universities. Our printer, old and unusable, can not meet the increased demand. Therefore, we were applying for a new one.
We hope that you can furnish us with it as soon as possible, so that our work will not be further delayed. Thank you for the trouble.
Yours sincerely,
Director Li
