RS-232 Serial Interface

Also if possible, eliminate sending white space (spaces or tabs) at the end of lines if it is not necessary.

Memory intensive applications may require an adjustment to the allocation of global memory for optimal performance. This may include applications where:

•the form length is greater than 24 inches

•a great number of forms or fonts are being used interchangeably

•the printing resolution is 400 dpi

Refer to the L5035 Maintenance Manual or contact a qualified service representative for details on adjusting the global memory.

RS-232 Serial Interface

This interface is used with bit serial devices compatible with EIA® RS-232E or CCITT V.24 standards. The interface circuit characteristics are compatible with the Electronic Industry Association Specification.

The printer is configured as Data Terminal Equipment (DTE).

The serial data transfer baud rate is selectable from the control panel. The input format consists of a single start bit, 7 or 8 data bits, and one or two stop bits. The operator can set the number of data bits from the control panel. The data bits are interpreted with the least significant bit first. The operator can also set parity checking via the control panel. The printer interface uses a first-in/first-out buffer with the size selectable from the control panel. The asynchronous interface accepts data as it is provided by the host computer.

The maximum cable length from the host computer to the printer is 50 feet.

The maximum baud rate supported by the RS-232 serial interface is 19.2 KB.

Printing at full-rated speed may require either an RS-422 or parallel connection for wide format printing applications.
