对于有较多A3打印需求,同时又需要A4幅面打印、复印、扫描,有时还要收发传真的用户来说,常见的办公设备组合是A3幅面的单功能打印机+A4幅面的一体机,或者A3幅面的复合机。无论选择哪一种组合,都需要付出高额的成本,而且会占用较大的存放空间。 For those who have more A3 printing needs, but also need A4 format printing, copying, scanning, and sometimes send and receive faxes, the common office equipment portfolio is A3 format single-function printer + A4 format one machine, or A3 The breadth of the complex machine. Whichever combination you choose, you have to pay a high cost and take up more storage space.
