Two types of drive for 820 Series: one is installed directly under Windows9x/ME/ 2000 /XP/WIN7/WIN8, the other is to drive through Ethernet.
(1) Install driver under Windows
Add printer in the Windows, and appoint the driver documents in the driver disk to Windows. It can print once you start print command in the program. In this way, Windows’ printer driver turns characters to graphics dot-matrix for printing.
(2) Install driver by Interface
In this way, no need for drive program. It can print just when it output character to port and the hard font inside printer realizes the character exchange printing. By port for driver, the printing type transforms page printing to line printing, which controls printing more conveniently.
If you use port driver, it need instruction set to control printing of the printer, while 820 series have already integrated ESC/POS instruction set inside the printer.
