There is no reason to think that any particular scanner will support that capability. Many of them get information about the total length of the scan before they start, and there is a firmware limit to that value.
You will need a simplistic scanner that just streams data of an indeterminate length until the host stops asking for data. allan On Mon, Aug 31, 2020 at 3:05 PM Michael Rose <bugfi...@hotmail.co.uk> wrote: > > Hello everyone, > > I'm new here so please forgive me if I'm not doing things right.
