LQ-870 Impact Printer

Q:
I'm printing serial, my baud rate is at 9600, and intermittently the printer will lose data. What can I do to correct this?
A:
If you are using a non-buffered serial interface board and XON/XOFF is enabled, the XOFF signal may not reach the printer in time to delay data transmission that would result in an overflow and loss of data. If you can use a DTR setting, change XON/XOFF to DTR. If you must use XON/XOFF, try decreasing the baud rate. Another option would be to purchase a 32KB buffered serial interface card (C823071). The buffered serial interface has a flag reset timing, which sets aside additional buffer space to "catch" the data overflow. The flag reset timing feature settings are selectable through dip switches on the serial interface card.
