I’m confused what version are you runnning?
Here is the link to the Epicare document on creating a label using the GenPCID
Reviewing the two documents on that KB I note there is a slight difference between using the genPCID and the other bartender labels. It mentions to set Run Schedule to immediate and Print Action toAuto Preview. I don’t think that is correct. I think it should be Run Schedule to be immediate and Print Action to AutoPrint and the printer set to Default.
Then it should print to the default printer after you have setup your bartender integration etc.
Here is a good post on server side printing Let's talk about SSP (server-side printing) Nathan even goes as far as setting Run Schedule to Queued for testing and keeping that way.
This one should help with setting up the bartender integration
