Hi, 

I've installed the base_report_to_printer and configure the invoice of POS to go directly to the printer.

It works, when I click on invoice the printer prints something, but not my report!

It prints this : 

%PDF-1.4
1 0 obj
<<
/Title ()
/Creator ()
/Producer ( wkhtmltopdf)
/CreationDate (D:20151123183013Z)

endjob
3 0 obj

/Type /ExtGState
/SA true
/SM 0.02
/ca 1.0
/CA 1.0
/AIS false 
/SMask /None>>
endobj
4 0 obj
[/Pattern /DeviceRGB]
endjob
...................

 Do you have any ideas what am I missing ?

Thanks
