When using .to\_markdown I get output messages to stdout which I cannot seem to suppress:

* * *

=== Document parser messages ===

Using Tesseract for OCR processing.

OCR on page.number=0/1.

* * *

I have tried many strategies with no luck… Is there some way to disable these messages??

# Suppress all PyMuPDF/Tesseract messages entirely

os.environ[“PYMUPDF\_MESSAGE”] = “”  
os.environ[“PYMUPDF\_MESSAGE”] = “path:pymupdf\_logs.txt”

# Disable logging for pymupdf/pymupdf4llm

logging.getLogger(“pymupdfllm”).setLevel(logging.CRITICAL + 1)  
logging.getLogger(“pymupdf”).setLevel(logging.CRITICAL + 1)  
logging.getLogger(“pypdf”).setLevel(logging.ERROR)  
logging.getLogger(“fitz”).setLevel(logging.CRITICAL + 1)  
logging.getLogger(“tesseract”).setLevel(logging.CRITICAL + 1)

# Suppress MuPDF errors

fitz.TOOLS.mupdf\_display\_errors(False)

# Suppress MuPDF error and warning messages

pymupdf.TOOLS.mupdf\_display\_errors(False)  
pymupdf.TOOLS.mupdf\_display\_warnings(False)

# Redirect stdout

with open(‘output.txt’, ‘w’) as f:  
sys.stdout = f # Change the standard output to the file we created  
print(“This message goes to the file”)

Underpinning @Jamie_Lemon 's comment:  
Here is an example session that stores away pymupdf4llm’s message output:
