The ONLY way to set up USB printer on MFGPRO is refer to the manual for the specific printer, You will still use one of the lpt ports ie lpt4 for this purpose. If you mention your printer name & make I can check and revert with the settings.
I know this is an old thread, but I have run into this exact problem, and found nothing in the printer manual to cover it. Nothing I have found on the Internet so far has worked.
I am trying to set up a Dell Photo 944 All In One USB printer as a local printer for QAD, but I have not been able to get it to work.
Can anyone please help me out?
Thanks.
