Thermal Printer - Send image via /dev/usb/lp0

I am working with a Raspberry Pi Zero W, and I am attempting to print an image (jpg/png) file to the printer. Currently, I am having success using commands such as echo "hello" /dev/usb/lp0 and sending commands using commands such as echo -e "1B6D" | xxd -r -p | tee /dev/usb/lp0. My trouble comes when I want to send an image via the usb/lp0 method. Is it possible? Furthermore, I want to mention that using cups with the driver was also unsuccessful, and adding the printer using lpadmin was not successful either.

# lpadmin -p Citizen -v serial:/dev/usb/lp0
# lp hello -d Citizen
lp: Destination "Citizen" is not accepting jobs.
