>I developed an application (car/motor parking program) using VFP5 under Windows98. Using only one computer attached to two printers: one Epson TMU200D (parallel interface) and the other one is Epson TMU200B (serial interface - autocutter). The serial printer is used as a check-in printer that will print receipt for guest's vehicle who comes in and the parallel printer is used for printing the receipt for guests who check out. I've made the program send the receipt to the appropriate printer based on the entry on the screen (check in or check out). Everything runs ok but if I enter several car police numbers before the check-in printer finished printing then the printer will print garbage the auto-cutter feature doesn't work.

It's a pretty clear indication that the serial port is not configured properly - the handshaking mechanism used between theserial printer and the port is not behaving as expected. Thismaybe a matterof a setting for the port configuration regarding the handshaking mechanism, or an improperly constructed serial cable that does not pass the necessary control signal from the printer to the port to request a pause in output while the print device catches up.
