USB X Parallel Port - DOS programs

By eareas ·
I have some old DOS system wich runs under Windows command prompt terminal and this program uses local HP deskjet printer. DOS programs use printers thru logical pararallel referencies as LTP1, LTP2,etc.

HP says that new models of HP printers won't have compatibility with such programs anymore because they will only use USB ports , instead of parallel ones. Unfortunatelly , I will have to use this program because it's very complicated to translate it to VB or Delphi.

This issue will affects only the use of local printer because networks printers can be logicaly redirected to paralell ports.

I've asked HP and got no response. Can someone help me ?

I've run across the same issue, and there's no 'good' solution...you'll either need to dig up a printer with a parallel interface or use the mapped network printer solution.

Sorry...

Thank you for your reply.
I've realized that the only way to use this usb printer is to put it on the network , share it , and capture LTP1 or 2 on the user's workstation. It's a strange solution but it worked at least.

Thank you anyway.

Get a USB to parallel interface cable. Problem should be resolved.

Thank you for you reply.
Can you confirm that changing the cable it will be possible to use LPT1: or PRN referencies used by DOS program without getting an error ?
I am asking your confirmation because this is not a problem of communication link but logical reference made by DOS program .

Thank you anyway.

I don't agree with answer 2 because I don't think USB is support under DOS even you have a USB to parallel converter cable. Best option is to get a parallel printer. Epson still make some.

Thank you for your reply.

I 'll close this question . It seems there is no good solutiom at all. I think HP is sleeping. I can not understand why other printer manucfaturers see this is an opportunity to steal HP market.

Thank you anyway.
