POS for .NET and Epson OPOS

[Jeff Oakes]

We're using VS2008 SP1 on Vista SP1.
We have on a clean machine Epson OPOS for .NET 1.11.3 (tried .1 and .2 as
well)

I've created a logical device name for an Epson TM-T90 using Epson's setup
utility.
Epson's Check Health utility works fine.

When we run the sample app that is included with MS POS for .NET - we can
see the printer and its logical device name.

Use the source code for the same MS sample app, we get no printers listed
with logical names.

Using our own code - same problem.

It appears only pre-compiled applications can see these logical names. Of
course those apps were probably pre-compiled on VS2005 or pre SP1 VS2008.

All of these source versions worked fine prior to SP1 for VS2008 or SP1 for
Vista or SP1 for .NET Framework 3.5.

Any ideas? We cannot continue development as we can no longer see devices.

Thanks!

If the Sample Application is able to see the printer then you should be
able to as well.

Are you asking the POSExplorer to return a list of all available
printers or are you asking for the specific printer by name? Try asking
for a list and see if the printer in question is returned. If asking by
name, perhaps the name is not an exact match.

Hope this helps,

I'll try to remember to test this out next week at work. If I forget,
you can send an e-mail to the POS for .NET team blog and mention this
issue to remind me. :-)

As it turns out, there is a permissions problem in Windows Vista!

Epson/Microsoft found this out for me.

You have to use an XP machine to create the file using Epson's Setup
utility. Then copy that file over to Vista to use.

Once the file exists on the Vista machine it can be edited as usual. Just
can't be created from Vista to begin with!

Hi

Now, I have found a better solution for this problem!

I have simply start Epson.opos.tm.setpos.exe elevated! And after
configuration is saved, it needs a shutdown/restart. Afterwards it works fine.
