CONFUSED WITH PRINTER

Today, student do their work / project in computer then print. A junior high school student want to print her work. "Sir, please help me," she ask. I help her. For moment success to print. Than, can not. I try to handle but can not. I'm confused (bingung) with the printer. What's happening? I  left it for moment, just as surrender. Than some teacher come. They are Ms Gracia and Ms Yany. Ms Gracia press the button . And..... what result? The printer run, can print. "Seldom the other people know than me," I say to my heart. Than I try to help student and teacher that want to print. I success too.
