7.1.2 Timing of serial RS232 /TTL interface
The standard timing is shown in the picture below.
The Data format can be set via Menue (only printers
with EEPROM).
7.2 USB Interface
USB Printer Class
The USB device class is "Printer Class".
When plugged in, the PC will report "USB printer sup-
port" and install a "USB001"USB port.
Either the standard printer driver of the "system78" or the
port monitor can be used. During installation of the prin-
ter driver, it can be easily guided onto the USB port.
Windows® XP and Windows® CE handle the nu-
meration of a printer differently. Therefore, the prin-
ter must be conficurated to the operating system
before delivery.
