# rasterprynt
rasterprynt is a Python library and program to print raster graphics on various label printers. As of writing, the following printers are supported:
- Brother PT P950NW
- Brother PT 9800PCN
This uses an undocumented reverse-engineered protocol, similar to the one in use by [brother_ql](https://github.com/pklaus/brother_ql/tree/master/brother_ql).
At the moment, the tape width is fixed at 18mm and the quality as high, but patches are always welcome.
## Installation
As a depency, depend on the PyPi package `rasterprynt`. To install dependencies for a command-line installation, type
$ pip install -r requirements.txt
## Command Line Usage
All functionality is available as a command-line program, like this:
$ python -m rasterprynt 192.168.1.123 img1.png img2.jpg img1.png --top-margin 10
## Library Usage
The main method is `rasterprynt.prynt`, which takes a list of images. Cuts will be inserted in between the images.
import rasterprynt
import PIL.Image
# Enter the IP address of your printer below
printer_ip = '192.168.1.123'
img1 = PIL.Image.open('example1.png')
img2 = PIL.Image.open('example2.png')
data = rasterprynt.prynt([img1, img2, img1], printer_ip)
## Additional utilities
`plotimg.py` provides a way to do the reverse transformation.
