Pdf-tools fails to print

Question

Using pdf-tools I attempt to print via pdf-print-misc-document though nothing gets printed?

In messages I see without any errors: Print job started: /usr/bin/lpr -P myprinter -o media=a4 -o InputSlot=Tray2 /home/temp.pdf

Running the same command from the terminal prints immediately

$ /usr/bin/lpr -P myprinter -o media=a4 -o InputSlot=Tray2 /home/temp.pdf

.spacemacs

(custom-set-variables
'(pdf-misc-print-programm "/usr/bin/lpr") 
'(pdf-misc-print-programm-args (quote ("-P myprinter" "-o media=a4" "-o InputSlot=Tray2")))
)
