But if we remove `ax.xaxis.set_major_locator`, the error disappears.\r\n\r\n### Code for reproduction\r\n\r\n```Python\r\nfrom matplotlib import ticker\r\nimport matplotlib.pyplot as plt\r\n\r\nplt.rcParams['text.usetex'] = True\r\nplt.rcParams['font.family'] = 'serif'\r\nplt.rcParams['font.serif'] = 'Times'\r\n\r\nfig, ax = plt.subplots()\r\nax.plot([1, 2, 3])\r\n\r\n#!!!!! If we comment out the following line, the code will run without error\r\nax.xaxis.set_major_locator(ticker.LinearLocator(numticks=5))\r\n\r\nfig.savefig('test.pdf')\r\n```\r\n\r\n\r\n### Actual outcome\r\n\r\nThrows error:\r\n```\r\nTraceback (most recent call last):\r\n  File \"e:\\research\\article\\\\bug.py\", line 14, in \u003cmodule\u003e\r\n    fig.savefig('test.pdf')\r\n  File \"E:\\scoop\\apps\\miniconda3\\current\\envs\\all\\lib\\site-packages\\matplotlib\\figure.py\", line 3390, in savefig\r\n    self.canvas.print_figure(fname, **kwargs)\r\n  File \"E:\\scoop\\apps\\miniconda3\\current\\envs\\all\\lib\\site-packages\\matplotlib\\backend_bases.py\", line 2193, in print_figure\r\n    result = print_method(\r\n  File \"E:\\scoop\\apps\\miniconda3\\current\\envs\\all\\lib\\site-packages\\matplotlib\\backend_bases.py\", line 2043, in \u003clambda\u003e\r\n    print_method = functools.wraps(meth)(lambda *args, **kwargs: meth(\r\n  File \"E:\\scoop\\apps\\miniconda3\\current\\envs\\all\\lib\\site-packages\\matplotlib\\backends\\backend_pdf.py\", line 2807, in print_pdf\r\n    self.figure.draw(renderer)\r\n  File \"E:\\scoop\\apps\\miniconda3\\current\\envs\\all\\lib\\site-packages\\matplotlib\\artist.py\", line 95, in draw_wrapper\r\n    result = draw(artist, renderer, *args, **kwargs)\r\n  File \"E:\\scoop\\apps\\miniconda3\\current\\envs\\all\\lib\\site-packages\\matplotlib\\artist.py\", line 72, in draw_wrapper\r\n    return draw(artist, renderer)\r\n  File \"E:\\scoop\\apps\\miniconda3\\current\\envs\\all\\lib\\site-packages\\matplotlib\\figure.py\", line 3154, in draw\r\n    mimage._draw_list_compositing_images(\r\n  File \"E:\\scoop\\apps\\miniconda3\\current\\envs\\all\\lib\\site-packages\\matplotlib\\image.py\", line 132, in _draw_list_compositing_images\r\n    a.draw(renderer)\r\n  File \"E:\\scoop\\apps\\miniconda3\\current\\envs\\all\\lib\\site-packages\\matplotlib\\artist.py\", line 72, in draw_wrapper\r\n    return draw(artist, renderer)\r\n  File \"E:\\scoop\\apps\\miniconda3\\current\\envs\\all\\lib\\site-packages\\matplotlib\\axes\\_base.py\", line 3070, in draw\r\n    mimage._draw_list_compositing_images(\r\n  File \"E:\\scoop\\apps\\miniconda3\\current\\envs\\all\\lib\\site-packages\\matplotlib\\image.py\", line 132, in _draw_list_compositing_images\r\n    a.draw(renderer)\r\n  File \"E:\\scoop\\apps\\miniconda3\\current\\envs\\all\\lib\\site-packages\\matplotlib\\artist.py\", line 72, in draw_wrapper\r\n    return draw(artist, renderer)\r\n  File \"E:\\scoop\\apps\\miniconda3\\current\\envs\\all\\lib\\site-packages\\matplotlib\\axis.py\", line 1391, in draw\r\n    tick.draw(renderer)\r\n  File \"E:\\scoop\\apps\\miniconda3\\current\\envs\\all\\lib\\site-packages\\matplotlib\\artist.py\", line 72, in draw_wrapper\r\n    return draw(artist, renderer)\r\n  File \"E:\\scoop\\apps\\miniconda3\\current\\envs\\all\\lib\\site-packages\\matplotlib\\axis.py\", line 295, in draw\r\n    artist.draw(renderer)\r\n  File \"E:\\scoop\\apps\\miniconda3\\current\\envs\\all\\lib\\site-packages\\matplotlib\\artist.py\", line 72, in draw_wrapper\r\n    return draw(artist, renderer)\r\n  File \"E:\\scoop\\apps\\miniconda3\\current\\envs\\all\\lib\\site-packages\\matplotlib\\text.py\", line 793, in draw\r\n    textrenderer.draw_tex(gc, x, y, clean_line,\r\n  File \"E:\\scoop\\apps\\miniconda3\\current\\envs\\all\\lib\\site-packages\\matplotlib\\backends\\backend_pdf.py\", line 2267, in draw_tex\r\n    pdfname = self.file.dviFontName(dvifont)\r\n  File \"E:\\scoop\\apps\\miniconda3\\current\\envs\\all\\lib\\site-packages\\matplotlib\\backends\\backend_pdf.py\", line 938, in dviFontName\r\n    psfont = tex_font_map[dvifont.texname]\r\n  File \"E:\\scoop\\apps\\miniconda3\\current\\envs\\all\\lib\\site-packages\\matplotlib\\dviread.py\", line 905, in __getitem__\r\n    raise LookupError(\r\nLookupError: An associated PostScript font (required by Matplotlib) could not be found for TeX font 'zptmcm7y' in 'E:/scoop/apps/miktex/current/texmfs/data/fonts/map/pdftex/pdftex.map';
