I have just been trying to connect a printer to my AT clone (a COPAM AT). It did not work. At first I thought it must be a printer failure, so I tried with another printer and cable. Same result. I have two printer ports (parallel) LPT1 and LPT2. Same result on both of them so HW failure also seems doubtful. I am using standard 3.20 DOS. Other people have connected printers to COPAMs (I think they are sold under another name outside Sweden - anyone know what) without problems. The DIP switches inside the AT are OK (for both ports) and both printers work OK on other machines. The symptoms are as follows: The DOS print command says all is OK for default device PRN = LPT1 and for LPT2. The system hangs sometimes afterwards and always if I try a print screen. Sometimes I gat the first line of the file I'm trying to print out after a long delay. Sometimes the second and third lines apear about 15 minutes later. What's going on? Can it be that both of the printer ports are faulty. Am I missing something obvious. Any help and suggestions would be welcome. (excluding comments that I should buy a new machine!) Mike Williams
