Epson Printer Configuration tool via SNMP (TCP/IP)

## Product Overview

The *Epson Printer Configuration Tool* simplifies the management of Epson printers connected via Wi-Fi over the SNMP protocol (TCP/IP, not USB).

A range of features are offered for both end-users and developers, making it easier to administer and maintain Epson printers.

## Key Features

- __SNMP Interface__: Seamlessly connect and manage Epson printers using SNMP over TCP/IP, supporting Wi-Fi connections.
- __Detailed Status Reporting__: Produce a comprehensive printer status report (with options to focus on specific details).
- __Advanced Maintenance Functions__:
    - Reset the ink waste counter.
    The ink waste counters track the amount of ink discarded during maintenance tasks to prevent overflow in the waste ink pads. Once the counters indicate that one of the printer pads is full, the printer will stop working to avoid potential damage or ink spills. Resetting the ink waste counter extends the printer operation while a pad maintenance or replacement is programmed.
    - Adjust the power-off timer for more accurate energy efficiency.
    - Access various administrative and debugging options.
    - Read and write to EEPROM addresses for advanced configurations.
    - Dump and analyze sets of EEPROM addresses.
- __User-Friendly Interfaces__:
    - __Graphical User Interface (GUI)__: Intuitive interface with an autodiscovery function that detects printer IP addresses and model names.
    - __Command Line Tool__: For users who prefer command-line interactions, providing the full set of features.
    - __Python API Interface__: For developers to integrate and automate printer management tasks.

The GUI can automatically find and display printer IP addresses and model names, allowing users to:

- Check printer status.
- Set the power-off timer.
- Reset the ink waste counter.
- Configure the _First TI Received Time_.
  The *First TI Received Time* in Epson printers typically refers to the timestamp of the first transmission instruction to the printer when it was first set up. This feature tracks when the printer first operated.

The software provides a configurable printer dictionary, which can be easily extended. In addition, a tool allows importing and converting 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.

## Usage

### Running the pre-built GUI executable code

The *epson_print_conf.zip* archive in the [Releases](https://github.com/Ircama/epson_print_conf/releases/latest) folder incudes the *epson_print_conf.exe* executable asset; the ZIP archive is auto-generated by a [GitHub Action](.github/workflows/build.yml). *epson_print_conf.exe* is a Windows GUI that can be directly executed.

### Running the GUI with Python

Run *ui.py* as in this example:

```
python ui.py
```

This GUI runs on any Operating Systems supported by Python (not just Windows), but needs that [Tkinter](https://docs.python.org/3/library/tkinter.html) is installed. While the *Tkinter* package might be generally available by default with Windows, [it needs a specific installation on other Operating Systems](https://stackoverflow.com/questions/76105218/why-does-tkinter-or-turtle-seem-to-be-missing-or-broken-shouldnt-it-be-part).

GUI usage:

```
python ui.py [-h] [-P PICKLE_FILE] [-O]

optional arguments:
  -h, --help            show this help message and exit
  -P PICKLE_FILE, --pickle PICKLE_FILE
                        Load a pickle configuration archive saved by parse_devices.py
  -O, --override        Replace the default configuration with the one in the pickle file instead of merging (default
                        is to merge)

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.

## Creating an executable asset for the GUI

Alternatively to running the GUI via `python ui.py`, it is possible to build an executable file via *pyinstaller*.

Install *pyinstaller* with `pip install pyinstaller`.

The *epson_print_conf.spec* file helps building the executable program. Run it with the following command.

```bash
pip install pyinstaller  # if not yet installed
pyinstaller epson_print_conf.spec -- --default
```

Then run the executable file created in the *dist/* folder, which has the same options of `ui.py`.

An alternative way to create the executable file from *ui.py* without using *epson_print_conf.spec* is the following:

```bash
pyinstaller --onefile ui.py --name epson_print_conf --hidden-import babel.numbers --windowed
```

A file named *gui.py* is also included (similar to *ui.py*), which automatically loads a previously created configuration file that has to be named *printer_conf.pickle*, merging it with the program configuration. (See below the *parse_devices.py* utility.) To build the executable program with this file instead of the default *ui.py*, run the following command:

```bash
pip install pyinstaller  # if not yet installed
curl -o devices.xml https://codeberg.org/attachments/147f41a3-a6ea-45f6-8c2a-25bac4495a1d
python3 parse_devices.py -a 192.168.178.29 -s XP-205 -p printer_conf.pickle  # use your default IP address and printer model as default settings for the GUI
pyinstaller epson_print_conf.spec
```

When the build operation is completed, you can run the executable program created in the *dist/* folder. It does not have options, embeds the *printer_conf.pickle* file and starts with the default IP address and printer model defined in the build phase.

The Windows *epson_print_conf.exe* executable file is automatically generated by a [GitHub Action](.github/workflows/build.yml). It is included in a ZIP file named *epson_print_conf.zip* and uploaded into the [Releases](https://github.com/Ircama/epson_print_conf/releases/latest) folder.

As mentioned in the [documentation](https://pyinstaller.org/en/stable/), PyInstaller supports Windows, MacOS X, Linux and other UNIX Operating Systems. It can create an executable file compatible with the operating system that is used to build the asset.

## Utilities and notes

### parse_devices.py

Within a [report](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 includes 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. Alternatively, the program is able to create a *pickle* configuration file (check the `-p` lowercase option), which the other programs can load (with the `-P` uppercase option and in addition with the optional `-O` flag).

The `-m` option is optional 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:

```
parse_devices.py [-h] [-m PRINTER_MODEL] [-l LINE_LENGTH] [-i] [-d] [-t] [-v] [-f] [-e] [-c CONFIG_FILE] [-s DEFAULT_MODEL] [-a HOSTNAME] [-p PICKLE_FILE] [-I]
                        [-N] [-A] [-G] [-S] [-M]

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
  -s DEFAULT_MODEL, --default_model DEFAULT_MODEL
                        Default printer model. Example: -s XP-205
  -a HOSTNAME, --address HOSTNAME
                        Default printer host name or IP address. (Example: -a 192.168.1.87)
  -p PICKLE_FILE, --pickle PICKLE_FILE
                        Save a pickle archive for subsequent load by ui.py and epson_print_conf.py
  -I, --keep_invalid    Do not remove printers without write_key or without read_key
  -N, --keep_names      Do not replace original names with converted names and add printers for all optional names
  -A, --no_alias        Do not add aliases for same printer with different names and remove aliased printers
  -G, --no_aggregate_alias
                        Do not aggregate aliases of printers with same configuration
  -S, --no_same_as      Do not add "same-as" for similar printers with different names
  -M, --no_maint_level  Do not add "Maintenance required levelas" in "stats"

Generate printer configuration from devices.xml
```

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:

```
[{'ip': '192.168.178.29', 'hostname': 'EPSONDEFD03.fritz.box', 'name': 'EPSON XP-205 207 Series'}]
```

### Other utilities

```python
from epson_print_conf import EpsonPrinter
import pprint
printer = 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 = 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 = 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):

```python
from epson_print_conf import EpsonPrinter
import pprint
printer = 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
```

## API Interface

- `model`: printer model
- `hostname`: IP address or network name of the printer
- `port`: SNMP port number (default is 161)
- `timeout`: printer connection timeout in seconds (float)
- `retries`: connection retries if error or timeout occurred
- `dry_run`: boolean (True if write dry-run mode is enabled)

### Exceptions

```
TimeoutError
ValueError
```

(And *pysnmp* exceptions.)
