Hello,
I am new to the list and although I am not sure if I am in the right place
or if anyone here can offer some advice. I am trying to make a small
sheetfeed scanner compatible with eSCL/AirScan. It currently works with
VueScan but fails on Mopria Android and OSX. I am not some big manufacturer
nor contracted by one. This is for a small embedded use.
As I find no coherent list of these HTML/XML exchanges and how they should
be for a successful scan, nor do I have a genuine device to capture
packets from, most of the information I have gleaned elsewhere to produce
the following which is actually from eSCL/ScanneStatus while scanning .
The problem I am having is that OSX is looking for some different status in
ScannerStatus than I am offering but have no idea what to tell it. VueScan
on the other hand works 100% but it appears it takes the "201 Created" and
"Location: /eSCL/folder" from the header, ingnoring ScannerStatus and
starts the download from there
Any help appreciated, thanks.
Mark
