I have a website in django, I only going to  visit the website using a Raspberry Pi,  I need print a data, and for print I am using a Thermal Printer in the Raspberry Pi.
I can print from the Raspberry pi using 
("/dev/ttyAMA0",19200,timeout=5)
for obtain serial communication
This work fine  but only when the project is hosting local in the raspberry Pi , but the django project is hosting in a VPS with ubuntu  then I have problems for printer from the Raspberry PI.
because in ubuntu there are not    
"/dev/ttyAMA0"
How I can work with this thermal Printer  from a django project for print  correctly using a RaspberryPi
install a print server on the pi and serve the printer. you may need some sort of tunnel so that the VPS can reach the pi.
