default printer

基本解释

If you see a check mark next to the printer icon, the printer is your default printer.
如果打印机图标旁边显示复选标记，则说明该打印机是您的默认打印机。
The expected behavior is that the document should print to the first non-default printer found in the printers collection.
预期中想得到的是文件将会打印到最初的在打印机组列中能找到的非默认的打印机。
Of course, after he learns that the little printer means "print one copy of the current document on the default printer now, " he won't have trouble with it again.
当然，在学会这个小打印机图标代表“用能用的打印机打印一份当前文档”之后，他就不会再有麻烦了。
