you save figure pdf, use subprocess print pdf. on *nix, lpr used:

import matplotlib.pyplot plt import numpy np import subprocess import shlex  n=20 x=np.linspace(0,np.pi,n) y=np.sin(x) plt.plot(x,y) fname='/tmp/test.pdf' plt.savefig(fname) proc=subprocess.popen(shlex.split('lpr {f}'.format(f=fname)))
