What BradtheRad indicated is the reason for the damage caused in the parallel cable. This was a major problem when parallel interface was in use (called as centronics interface). One should not connect the printer interface cable(parallel type) to a PC , unless the printer is powered.
Enhanced Parallel Port (EPP) was created by Intel, Xircom, and Zenith in 1991. EPP allows for much more data, 500 kilobytes (KB) to 2 megabytes (MB) The maximum speed of the centronics interface is 150 kilobits per second, though contends that the cable typically offered no more than 10 kbps connectivity.
It is a self-made construction of LCD display for a PC.

Your question has been rather unclear, so the contributors assumed you're referring to a standard parallel printer (centronics) interface. Apparently you are talking instead about the manufacturer specific hardware interface of a thermal printer device. There's no chance to get suitable help without exactly telling the manufacture and device type a
More information is needed. What type of printer is this? What is the printer interface (USB, serial, standard centronics parallel)? If the printer 'host-based', meaning that it relies of drivers on the computer-side for processing, then your job is going to be quite difficult. If you can choose your own printer, find an older dot-matr
What's the printer model number? Does it have a centronics port?
Hi, IEEE1284 is not a Chip, it is an IEEE Standard for the signal handshaking method for the parallel port of today's PC, describing three modes of its operation,viz., 1.Compatibility Mode, based on signals of the Old centronics port, 2.Extended Capabilities Port (ECP) Mode, and 3. Extended Parallel Port (EPP) Mode. It is a Priced dcument availab
it's easy to find out USB-2-Parallel port adaptors but they are only intended to connect an USB port to a centronics connector printer using USB printing support integrated in XP (as USB printer), in other words you have a supporting driver but it's not anything to connect a program dealing directly with parallel port (as opossed to a virtual paral
I build a similar device many years ago without any uC. You only need a photo diode with a sensitive area that is big enough to gather the complete beam. I think I used something like this centronics type (big noise !!!): Then you need an OpAmp, potis, resitors, caps and a panel meter - t
I have the PCL for HPlaserJet 6P/6MP. Could i use this for the Epson 80 column dot matrix interfacing using the microcontroller ? Could i get the necessary connection details with that of the 8051? should i go by the parallel centronics way ? regards, karthik bala guru.
Hi there Can someone tell me how to connect 6 switches to lpt port(25 pin or centronics 36 pin) to be able to check their states? What adresses i should use(base adress h378). THX for any help.
