Is it permissible to stop printing within the school and print for students on a private account the same number of pages that were printed for private use, in return for what was taken?

It is not permissible to use the company's work tools, such as the photocopier, for personal matters, unless there is explicit or customary permission from the employer. This is because these tools are a trust (amanah) that must be preserved and not disposed of except with authorization. If personal papers are printed, then please ensure that printing an equivalent quantity for work purposes is sufficient to clear one's conscience and return the right to the employer.
