Fuzhou Shangchen Technology answers for you:

Simple explanation: 1: When purchasing a printer, you need to pay attention to whether to use an office commercial printer or an industrial printer according to your own printing volume. General companies can choose small desktop bar code printers, commercial bar code printers with large printing volume, and industrial bar code printers in factories.

2. Choose the printing resolution you want according to the media you print, the consumables you print and the printing quality you pursue. Bar code printers are classified according to printing accuracy, mainly including 203dpi, 300dpi, 400dpi and 600dpi. These printers have high requirements on printing accuracy (such as high bar code density on jewelry, mobile phones and electronic components), and models above 300dpi can be selected. If the printing accuracy is not high, it is generally enough to choose 203dpi model, because the higher the printing accuracy, the longer the printing time.
