Looking for a bit of help here on this one.
I have a work related task that requires us to output via LPT1 to two different printers, one for DHL labelling and one for TNT. At present we use a manual T-switch to switch between the two.
Following a Eureka moment we think we should be able to connect both printers all the time as they use completely different coding structures and will therefore ignore code not intented for them.
The problem I have is where can I get a double headed parallel lead, one end in the PC and the other two ends in the printers?
