# epson_print_conf
Epson Printer Configuration tool via SNMP (TCP/IP)
## Features
- Access the Epson printer via SNMP (TCP/IP; printer connected over Wi-Fi)
- Print the advanced status of the printer, with the possibility to restrict the query to specific information
- Other inspection features:
- Read and write EEPROM addresses
- Dump a set of EEPROM addresses
- Reset ink waste
- Change power off timer
- Other admin stuffs and debug options
- both a GUI and a command line tool
- Python API interface
The GUI has an autodiscovery function which finds the printer IP addresses and their model names. By manually filling the printer model and the IP addresses in the related input boxes, the GUI can be used to get the printer status and to reset the ink waste counter.
The software provides a configurable printer dictionary, which can be easily extended. There is also a tool to import an extensive Epson printer configuration DB.
## Installation
Install requirements using *requirements.txt*:
```bash
git clone https://github.com/Ircama/epson_print_conf
cd epson_print_conf
pip install -r requirements.txt
```
Alternatively, install requirements via command line:
```
git clone https://github.com/Ircama/epson_print_conf
pip3 install pyyaml
pip3 install pyasn1==0.4.8
pip3 install git+https://github.com/etingof/pysnmp.git
pip3 install tkcalendar
pip3 install pyperclip
cd epson_print_conf
```
With Python 12, also: `pip3 install pyasyncore`.
Notes (at the time of writing):
- [before pysnmp, install pyasn1 with version 0.4.8 and not 0.5](https://github.com/etingof/pysnmp/issues/440#issuecomment-1544341598)
- [pull pysnmp from the GitHub master branch, not from PyPI](https://stackoverflow.com/questions/54868134/snmp-reading-from-an-oid-with-three-libraries-gives-different-execution-times#comment96532761_54869361)
This program exploits [pysnmp](https://github.com/etingof/pysnmp), with related [documentation](https://pysnmp.readthedocs.io/).
It is tested with Ubuntu / Windows Subsystem for Linux, Windows.
## Creating an executable for the GUI
Install pyinstaller if not already installed with `pip install pyinstaller`.
Run: `pyinstaller --onefile --noconsole ui.py`.
Run the exe file created in the *dist/* folder.
## Usage
Running the GUI:
```
python ui.py
```

Epson Printer Configuration via SNMP (TCP/IP)
```
Examples:
```bash
# Print the status information (-i is not needed):
python3 epson_print_conf.py -m XP-205 -a 192.168.1.87 -i
# Reset all waste ink levels to 0:
python3 epson_print_conf.py -m XP-205 -a 192.168.1.87 --reset_waste_ink
# Change the first TI received time to 31 December 2016:
python3 epson_print_conf.py -m XP-205 -a 192.168.1.87 --write-first-ti-received-time 2016 12 31
# Change the power off timer to 15 minutes:
python3 epson_print_conf.py -a 192.168.1.87 -m XP-205 --write-poweroff-timer 15
# Detect the read_key via brute force:
python3 epson_print_conf.py -m XP-205 -a 192.168.1.87 --detect-key
# Only print status information:
python3 epson_print_conf.py -m XP-205 -a 192.168.1.87 -q printer_status
# Only print SNMP 'MAC Address' name:
python3 epson_print_conf.py -m XP-205 -a 192.168.1.87 -q 'MAC Address'
# Only print SNMP 'Lang 5' name:
python3 epson_print_conf.py -m XP-205 -a 192.168.1.87 -q 'Lang 5'
# Write value 1 to the EEPROM address 173 and value 0xDE to the EEPROM address 172:
python3 epson_print_conf.py -m XP-205 -a 192.168.1.87 -W 173:1,172:0xde
# Read EEPROM address 173 and EEPROM address 172:
python3 epson_print_conf.py -m XP-205 -a 192.168.1.87 -R 173,172
```
Note: resetting the ink waste counter is just removing a warning; not replacing the tank will make the ink spill.
## Utilities and notes
### parse_devices.py
Within an [issue](https://codeberg.org/atufi/reinkpy/issues/12#issue-716809) in repo https://codeberg.org/atufi/reinkpy there is an interesting [attachment](https://codeberg.org/attachments/147f41a3-a6ea-45f6-8c2a-25bac4495a1d) which reports an extensive XML database of Epson model features.
The program "parse_devices.py" transforms this XML DB into the dictionary that *epson_print_conf.py* can use.
Here is a simple procedure to download that DB and run *parse_devices.py* to search for the XP-205 model and produce the related PRINTER_CONFIG dictionary to the standard output:
```bash
curl -o devices.xml https://codeberg.org/attachments/147f41a3-a6ea-45f6-8c2a-25bac4495a1d
python3 parse_devices.py -i -m XP-205
```
After generating the related printer configuration, *epson_print_conf.py* shall be manually edited to copy/paste the output of *parse_devices.py* within its PRINTER_CONFIG dictionary.
The `-m` option is mandatory and is used to filter the printer model in scope. If the produced output is not referred to the target model, use part of the model name as a filter (e.g., only the digits, like `parse_devices.py -i -m 315`) and select the appropriate model from the output.
Program usage:
```
python3 parse_devices.py [-h] -m PRINTER_MODEL [-l LINE_LENGTH] [-i] [-d] [-t] [-v] [-f] [-e] [-c CONFIG_FILE]
optional arguments:
-h, --help show this help message and exit
-m PRINTER_MODEL, --model PRINTER_MODEL
Printer model. Example: -m XP-205
-l LINE_LENGTH, --line LINE_LENGTH
Set line length of the output (default: 120)
-i, --indent Indent output of 4 spaces
-d, --debug Print debug information
-t, --traverse Traverse the XML, dumping content related to the printer model
-v, --verbose Print verbose information
-f, --full Generate additional tags
-e, --errors Add last_printer_fatal_errors
-c CONFIG_FILE, --config CONFIG_FILE
use the XML configuration file to generate the configuration
```
The output is better formatted when also installing [black](https://pypi.org/project/black/).
### find_printers.py
*find_printers.py* can be executed via `python find_printers.py` and prints the list of the discovered printers to the standard output. It is internally used as a library by *ui.py*.
Output example:
```json
[{'ip': '192.168.178.29', 'hostname': 'EPSONDEFD03.fritz.box', 'name': 'EPSON XP-205 207 Series'}]
```
### Other utilities
```
import epson_print_conf
import pprint
printer = epson_print_conf.EpsonPrinter()
# Decode write_key:
printer.reverse_caesar(bytes.fromhex("48 62 7B 62 6F 6A 62 2B")) # last 8 bytes
'Gazania*'
printer.reverse_caesar(b'Hpttzqjv')
'Gossypiu'
"".join(chr(b + 1) for b in b'Gossypiu')
'Hpttzqjv'
# Decode status:
pprint.pprint(printer.status_parser(bytes.fromhex("40 42 44 43 20 53 54 32 0D 0A ....")))
# Decode the level of ink waste
byte_sequence = "A4 2A"
divider = 62.06 # divider = ink_level / waste_percent
ink_level = int("".join(reversed(byte_sequence.split())), 16)
waste_percent = round(ink_level / divider, 2)
# Print the read key sequence in byte and hex formats:
printer = epson_print_conf.EpsonPrinter(model="ET-2700")
'.'.join(str(x) for x in printer.parm['read_key'])
" ".join('{0:02x}'.format(x) for x in printer.parm['read_key'])
# Print the write key sequence in byte and hex formats:
printer = epson_print_conf.EpsonPrinter(model="ET-2700")
printer.caesar(printer.parm['write_key'])
printer.caesar(printer.parm['write_key'], hex=True).upper()
# Print hex sequence of reading the value of EEPROM address 30 00:
" ".join('{0:02x}'.format(int(x)) for x in printer.eeprom_oid_read_address(oid=0x30).split(".")[15:]).upper()
# Print hex sequence of storing value 00 to EEPROM address 30 00:
" ".join('{0:02x}'.format(int(x)) for x in printer.eeprom_oid_write_address(oid=0x30, value=0x0).split(".")[15:]).upper()
# Print EEPROM write hex sequence of the raw ink waste reset:
for key, value in printer.parm["raw_waste_reset"].items():
" ".join('{0:02x}'.format(int(x)) for x in printer.eeprom_oid_write_address(oid=key, value=value).split(".")[15:]).upper()
```
Generic query of the status of the printer (regardless of the model):
```
import epson_print_conf
import pprint
printer = epson_print_conf.EpsonPrinter(hostname="192.168.1.87")
pprint.pprint(printer.status_parser(printer.snmp_mib("1.3.6.1.4.1.1248.1.2.2.1.1.1.4.1")[1]))
```
### Byte sequences
Header:
```
1.3.6.1.4.1. [SNMP_OID_ENTERPRISE]
1248. [SNMP_EPSON]
1.2.2.44.1.1.2. [OID_PRV_CTRL]
1.
```
Full header sequence: `1.3.6.1.4.1.1248.1.2.2.44.1.1.2.1.`
Read EEPROM (EPSON-CTRL), after the header:
```
124.124.7.0. [7C 7C 07 00]
<READ KEY (two bytes)>
65.190.160. [41 BE A0]
<LSB EEPROM ADDRESS (one byte)>.<MSB EEPROM ADDRESS (one byte)>
```
Example: `1.3.6.1.4.1.1248.1.2.2.44.1.1.2.1.124.124.7.0.73.8.65.190.160.48.0`
Write EEPROM, after the header:
```
7C 7C 10 00 [124.124.16.0.]
<READ KEY (two bytes)>
42 BD 21 [66.189.33.]
<LSB EEPROM ADDRESS (one byte)>.<MSB EEPROM ADDRESS (one byte)>
<VALUE (one byte)>
<WRITE KEY (eight bytes)>
```
Example: `7C 7C 10 00 49 08 42 BD 21 30 00 1A 42 73 62 6F 75 6A 67 70`
Example of Read EEPROM (@BDC PS):
```
<01> @BDC PS <0d0a> EE:0032AC;
EE: = EEPROM Read
0032 = Memory address
AC = Value
```
