# LBP3000 CAPT driver on Linux automated compile process
# Based on https://namvu.net/2021/07/setup-a-family-printer-with-a-raspberry-pi-1-and-canon-lbp-2900/
# But updated to use https://github.com/mounaiban/captdriver which is a more maintained fork

# This script was tested and confirmed working against a Debian GNU/Linux 11 (bullseye) on an x64 based PC
# (This script would also likely work on Ubuntu)

# Intent: This is intended to be used on a newly installed PC to install this old LBP3000 driver
#         if running again, you may need to pull any new changes from the source repo yourself.

# To run this shell script on gist (ref: https://gist.github.com/mob-sakai/174a32b95572e7d8fdbf8e6f43a528f6)
# Run this script via curl:

# Run this script via wget:

# Installing CUPS and the rest of the perequisites:
sudo apt install -y build-essential git autoconf libtool cups libcups2-dev libcupsimage2-dev

# Grab the source code:
git clone https://github.com/mounaiban/captdriver.git

# Compile the driver
pushd captdriver
autoreconf -i
./configure
make
make ppd
popd

# Install captdriver
#   The make install command above only copies the rastertocapt binary to the /usr/local/bin directory, 
#   while setting the necessary file ownerships and permissions. 
#   The cp command is still needed to place a copy of rastertocapt inside the CUPS filter directory.
pushd captdriver
sudo make install
popd

# Copy the files to their relevant locations
pushd captdriver
sudo cp src/rastertocapt /usr/lib/cups/filter/
sudo cp ppd/Canon*.ppd /usr/share/ppd/custom/
popd
