Python helper scripts to convert wireshark capture to text format. Uses tshark executable. Output example: For usb dumpsimport sys
import subprocess
TSHARK_PATH = "C:\\Program Files\\Wireshark\\tshark.exe"
if len(sys.argv) < 2:
print(f'Usage: {sys.argv[0]} <filename>')
exit(-1)
result = subprocess.run([
TSHARK_PATH,
"-2",
"-r",
sys.argv[1],
"-R", "usb.capdata",
"-T", "fields",
"-e", "frame.time_relative",
"-e", "usb.dst",
"-e", "usb.capdata"
], stdout=subprocess.PIPE)
if result.returncode != 0:
print(result.stdout.decode('ascii'))
exit(-1)
output = result.stdout.decode('ascii')
lines = output.splitlines()
for line in lines:
if not line:
break
parts = line.split('\t')
time = parts[0][:-6].rjust(7)
direction = '<<' if parts[1] == 'host' else '>>'
data = parts[2]
print(f'[{time}] {direction} {data}')For btsnoop dumpsimport sys
import subprocess
TSHARK_PATH = "C:\\Program Files\\Wireshark\\tshark.exe"
if len(sys.argv) < 2:
print(f'Usage: {sys.argv[0]} <filename>')
exit(-1)
result = subprocess.run([
TSHARK_PATH,
"-2",
"-r",
sys.argv[1],
"-R", "btspp.data",
"-T", "fields",
"-e", "frame.time_relative",
"-e", "hci_h4.direction",
"-e", "btspp.data"
], stdout=subprocess.PIPE)
if result.returncode != 0:
print(result.stdout.decode('ascii'))

This is a meta-issue for collecting traffic captures of an official app communication with various printer models. Preferred export format is JSON (if you're using wireshark: file > export packet dissections > as json), however plain text data is also fine. Don't forget to ensure your traffic capture does not contain any sensitive data: e.g. if you capturing USB traffic, don't forget to set a filter to only export printer packets, and exclude other USB devices.
Please share your captures using the following template:
General recommendations for capture scenarios (work in progress):
