Parallel Lead One PC to Two Printers

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?

The cable your referring to is a Parallel 'Y' Cable ...but this will be No different from using your T-Switch as the cable will be switched also.

If you send data to both printers at the same time ....one will print just pages & pages of rubbish.

What i think you want is one printer on a normal Parrallel Cable ......and the other connected via a USB to Parallel Adapter Cable ! :thumbsup:

We are pretty confident that sending the data to both printers at the same time will only print on the printer that interprets the programming language correctly. They use completely different text strings. If we send to the wrong printer now we get nothing I still believe I want the cable mentioned earlier.

USB to parallel printer cable £5.10, get 2 of these and address printers seperately.

These cables are designed to have two ends. The protocol for these cables is also designed in this way as well as the hardware that uses it. If you have a Y shaped cable you are actually not just connecting two printers to the computer at the same time. You are also connecting the printers to each other.

There is no telling what side effect or damage this could cause. Remember when a printer is connected the information goes both ways, so effectively they could be sending information to each other. Add to this any unknown implications of splitting the signal from the computer.

I don't think you will get a cable like this unless you make it.

Why are you so against the extremely simple and cheap usb route. You can pick up a usb to parallel adapter for about a fiver and leave one printer plugged in where it is.

Why get 2 ?
surely he only needs 1, connect one printer to this configured as USB2LPT port and the other to his actual LPT1 port

1-USB, 1-Parallel, or 2-USB makes no odds to me, just an option. :whistling:

I would go for would be to go all USB but that's just me...... :thumbsup:

The software outputs to LPT1, and works for everything else, at present we manually t-switch between two printers,. I really just need to stick with LPT1 as the output and then deal with accordingly.

Acer seem to do a parallel cable with two output's

Can you tell us what software this is. Not running in Windows environment?

no moobs its won't work m8, the data is not sent in one language or another it is sent in a digital stream and occassionally bit patterns will match but won't give the expected results
why not just shove a pci parallel port in and have lpt1 and lpt2
to prove this send a long print job to the wrong printer via the switch box

as these are labeling printers most jobs will be relatively small, eventually a code will match and a roll of labels will be wasted or the ecp will kick in and he will get nothing from either printer

m00bs you said you wanted help, but it seems you just want to source a cable and are not interested in any other views on your problem.

I asked for some info on what software your using so I could suggest some alternative options as my view is the split cable option is not possible. I also asked for a link to the cable you said Acer did as I am more than willing to learn I have got it wrong so I know better next time.

Now you may think I am on the wrong track, but if people take the time to answer in the thread you should really be willing to have a dialogue. :thumbsup:

as said before, just get a pci parallel port card for a tenner or a USB to parallel cable

job done

I am begining to think op is either running pre pci/usb hardware or is currently using all the usb ports for his mug warmer, desk fan, dancing hoola girl, mini fish tank, desk hoover and is not willing to give any of them up. ;-)

another classic case on hukd where someone requests help and disappears from the thread entirely without a word of gratitude!

CHARMING! lol
