Most of company have purchased their machine long ago, these machine may still function well, but some cases some of spare they may not found in market. We found that there is 8085 based leather scanning machine still in market, for that we need RS232 supported printer. unfortunate availability is very less, for that we found solution to convert RS232 to LPT. this board now support all company printer, without any limitation. It doesn’t require any alteration in machine. Just plug ad play!!!!!
