Reading the CPCL code from device

Hello!

 

I'm trying to read cpcl code from a device (X-ray portable spectrometer)
The device send the cpcl code via bluetooth to printer.

I don't have a printer, but I don't need it. I need to read the cpcl commands to get some data from device, such as elements concentrations, to make some automation process of sending data to database.

I get sending data into serial monitor on PC as cpcl commands but some commads are not readable. Here they are:

 

! U1 PW 609

! U1 TONE 100

! U1 SETLF 1

! U1 SETLP 7 0 0

! U1 LMARGIN 0

! U1 RY 3

! U1 X 8

! U1 SETLF 10

! U1 SETLP 7 0 24

These data contain information on the concentration of the element Ni = 10.01 %

Were is it?

The encoding is correct. What's wrong?
Thank you for your knowledge!
