I'm using the ZEBRA SDK to print into PVC cards, the text prints good, the imgages are good too, but when i try to print bar codes they show up as text (raw cpcl maybe?), and I have tried many thinks:

-reinstalled drivers (usb). -print over usb 2.0. -print with the 64bit SDK. -print with the 32bit SDK. -factory defaulted the printer settings. -updated the printer firmware to lasted version from the zebra website.

Queryset :

Tblog.objects.filter(status='success').annotate(groupby=TruncMonth('createtime',output_field=DateField())).values('groupby').annotate(total=Count('createtime')).order_by('-groupby')[:7]

if i change the TruncMonth function to TruncWeek the code should Grouping By Week,

the result when i am using Using TruncMonth and Using TruncDate this is the problem when Using TruncWeek

The result when using TruncMonth and TruncDate, the TruncWeek should returning like this too ,

What I discovered was that while it worked perfectly on the machine I was using to author and validate it, on my Server 2016 Core machine it seemed to misbehave when calling the function but that if I just ran the same check at the prompt it worked as expected.
