Can you print a string variable to printer - hammer - Apr-26-2022 I can not send a string variable to the printer because it keeps looking for a file. I have printed the string variable out on the terminal window and it is formatted and looks the way i want it but need a hard copy. I am using the variable to temporarily store lines of text with new line '\n': self.txt_print_var=self.txt_print_var+t+'\n' To try and print: os.system('lpr self.txt_print_var') lpr: Error - unable to access "self.txt_print_var" - No such file or directory Is there a way to print variable or am I going to have to create a file to get it to work RE: Can you print a string variable to printer - snippsat - Apr-26-2022 Don't use os.system anymore it has been replaced bye subprocess.To print a variable can eg use Popen.stdin Something like untested. import subprocess var = 'Test print' lpr = subprocess.Popen(["lpr"], stdin=subprocess.PIPE) lpr.stdin.write(var)With run .import subprocess from io import StringIO var = 'Test print' var_file = StringIO(var) lpr = subprocess.run(["lpr"], var_file) RE: Can you print a string variable to printer - hammer - Apr-30-2022 Thank you.
