Consult the documentation that came with your printer for setting up the printer for envelopes. Depending on the printer model, envelopes may have to be placed left, right, in the middle, and either face up or face down.
查看打印机文件，定义加载信封的方式，以确保它能被正确输送和打印。根据不同的打印模式，可能要求您将信封左对齐、右对齐或居中，要打印的页面向上或向下放入进纸器中。
