Section 3: Interface Specifications
DATA STREAMS
The data streams for X-On/X-Off and Ready/Busy flow control are constructed in the same way as they are for Ready/Busy flow control (<ESC>A . . Job#1 . . <ESC>Z<ESC>A . . Job#n . . <ESC>Z). An example of this would be: <ESC>A . . Job#1 . . <ESC>Z. All characters are in
ASCII.
UNIVERSAL SERIAL BUS (USB) ADAPTER
The Universal Serial Bus (USB) interface is a Plug-In Interface Module that can be installed by the user. It requires a driver (shipped with each printer that has the interface installed) that must be loaded on your PC and the PC must be configured to support USB peripherals using Windows 98 or above. Details for loading the USB driver are contained in the USB Interface Manual that is shipped with each printer with a USB Optional interface installed. Up to 127 devices may be connected to a USB port using powered hubs.

BI-DIRECTIONAL COMMUNICATIONS
This is a two-way communications protocol between the host computer and the printer, thus enabling the host to check printer status. When Bi-Com 4 communications is selected, there is no busy signal from the printer. The host must request the complete status from the printer, including ready/busy. The host may request status in two different ways.
ENQUIRE/ACK/NAK
In the Bi-Com 4 mode, the host transmits an ENQ (05 hexadecimal) to the printer and the printer will respond with its status within five milliseconds. If printing, it will respond upon finishing the current label, then resume printing. In order for this protocol to work properly with an RS232C
