I'm sorry about that. As I wrote, it works perfectly. In the
case of reads, of course, where it is supported.

My question was about writes, and it has been confirmed that
timeout paramaters are not supported there. Thanks Arne.

Now we need to weight the coding work against getting
network cables installed to the printers. Wired printers
will also "solve" the issue with the current code. We have
15-20 older similar Zebra label printers, all wired, and
we do not see these error scenarios with those.
All using the same C routine for the QIOW calls.


Jan-Erik.
