other hosts. The USB interface allows the printer to be connected to a computer that
supports peripherals attached to a USB bus. Up to 127 peripherals can be connected
to a single USB port.
When using an optional interface, DSW-8 on the Configuration panel must be placed
in the OFF position. When the IEEE 1284 interface is to be used, DSW-8 must be
placed in the ON position.
WARNING: Never connect or disconnect interface cables (or use a switch box) with
power applied to either the host or the printer. This may cause damage to the
interface circuitry in the printer/host and is not covered by warranty.
THE RECEIVE BUFFER
The CT printers have the ability to receive a data stream from the host in one of two
ways. The receive buffer may be configured to accept one print job at a time or
multiple print jobs. The single job print buffer is generally used by software programs
that wish to maintain control of the job print queue so that it can move a high priority
job in front of ones of lesser importance. The multiple job buffer, on the other hand
prints all jobs in the order they are received by the printer, and the order of printing
cannot be changed.
Single Job Buffer
The printer receives and prints one job at a time. Each job must not exceed 2.95MB.
