This package is trying to provide tools to print pictures using the Phomemo M02, M110, M120 and M220 thermal printers from Linux.
All the information here has been reverse-engineered sniffing the bluetooth packets emitted by the Android application.
python3-pybluez and phomemo-tools CUPS driver can be found at phomemo-tools RPM

- Send the picture to the printer (the python script currently only works with M02 printers):

-
Plug the USB printer cable
-
Check the printer is present:
$ lsusb

You can see the serial port in the dmesg and in /dev:

- Send the picture to the printer (the python script currently only works with M02 printers):
You need to be root or in the lp group
# tools/phomemo-filter.py my_picture.png > /dev/usb/lp0
On Debian you can have to install cups:
$ sudo apt-get update
$ sudo apt-get -y install cups
Then you can build and install phomemo-tools files:
$ cd cups
$ make
$ sudo make install
To connect using USB, you need python3-pyusb. For instance, on Fedora:
$ sudo dnf install python3-pyusb
On Fedora, SELinux seems to prevent the backend to create a bluetooth socket. If you have such error message in your syslog:
localhost.localdomain cupsd[2659]: Can\'t open Bluetooth connection: [Errno 13] Permission denied
You might need to disable SELinux enforcement to allow the backend to run correctly:
$ sudo semanage permissive -a cupsd_t
I didn't find a way to define correctly the SELinux rules to allow the backend to use bluetooth socket without to change the enforcement mode (the couple ausearch/audit2allow doesn't fix the problem).
- Switch on the printer
- Open the "Settings" window:
- Select the "Bluetooth" Panel:
- Select your bluetooth printer (here "Mr.in_M02"):
- Your printer must be paired but not connected ("Disconnected"):
- Select the "Printers" Panel:
You'll probably need to unlock it to be able to add a new printer.
Click on "Add a Printer...".
- Select your printer and click on "Add":
- Your printer will appear in the printers list:
- Click on the settings menu of the printer and select "Printing Options":
- Select "Media Size Label 50mmx70mm" and click on "Test Page":
- Check the result:
This definition will use the "phomemo" backend to connect to the printer:
$ sudo lpadmin -p M02 -E -v phomemo://DC0D309023C7 \
-P /usr/share/cups/model/Phomemo/Phomemo-M02.ppd.gz
Use ”Phomemo-M110.ppd.gz”. This driver is compatible with M110, M120, and M220. The -p option defines the printer name. It should be changed according to the printer used.
$ sudo lpadmin -p M110 -E -v phomemo://DC0D309023C7 \
-P /usr/share/cups/model/Phomemo/Phomemo-M110.ppd.gz
This definition will use the /dev/usb/lp0 device to connect to the printer:
$ sudo lpadmin -p M02 -E -v serial:/dev/usb/lp0 \
-P /usr/share/cups/model/Phomemo/Phomemo-M02.ppd.gz
Use ”Phomemo-M110.ppd.gz”. This driver is compatible with M110, M120, and M220. The -p option defines the printer name. It should be changed according to the printer used.
$ sudo lpadmin -p M110 -E -v serial:/dev/usb/lp0 \
-P /usr/share/cups/model/Phomemo/Phomemo-M110.ppd.gz
You can use the following command to check the options for your printer which will list the printer defaults with a "*":
$ lpoptions -d M02 -l
You can use the following command to print text using CUPS:
$ echo "This is test" | lp -d M02 -o media=w50h60 -
You can use the following command to print an image using CUPS:
$ lp -d M02 -o media=w50h60 my_picture.png
The M110, M120 & M220 printers have support for LabelWithGaps, Continuous and LabelWithMarks media types which can be specified as follows:
$ echo "This is test" | lp -d M110 -o media=w30h20 -o MediaType=Continuous
After dumpping bluetooth packets, it appears to be EPSON ESC/POS Commands.

If the picture is not finished, a new block marker must be sent with the remaining number of line (max is 255).
