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 M10e 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 2.95 MB.

MULTI JOB BUFFER

The printer is able to continuously receive print jobs, compiling and printing other jobs at the

same time. It acts much like a “print buffer” to maximize the performance of the host and the

printer. When using the RS232C Serial interface, the Multi Job Buffer uses either the Ready/

Busy with DTR (pin 20) or X-On/X-Off flow control protocols. See these sections for

more details. With an empty receiving buffer, the status of DTR is “high” (or an X-On

status if using X-On/X-Off), meaning the printer is ready to receive data. When the

receive buffer is holding 2.0 MB of data (1 MB from being full), DTR will go “low” (or

an X-Off is sent) indicating the printer can no longer receive data. This condition is

called “Buffer Near Full.”
