 # ptprnt
 
-This is a rewrite of [ptouch-print](https://git.familie-radermacher.ch/linux/ptouch-print.git) as a toy project for my personal amusement. The currently available solutions are good enough for generating labels, but i wanted to explore libusb and maybe improve the functionality of my label printer. All credits for reverse engineering the USB commands to Dominic Rademacher.
+A command-line label printer driver for Brother P-touch printers on Linux. Prints text labels directly from your terminal.
 
-## Dependencies
+## Example
-This project requires:
-- spdlog
-- libusb
-- pango
-- cairo
-- meson
-- gtest (optional, for testing, will be installed by meson)
-- gcov (optional, for coverage reports)
 
-Install dependencies on Arch Linux
+Too print a label, provide your text and optionally a font and a font size. This command will print the label below on a Brother P-Touch P700:
-``` bash
-pacman -S libusb spdlog pango cairo meson gcovr
-```
-
-Install dependencies on Debian/Ubuntu
-``` bash
-apt-get install libusb-1.0-0-dev libspdlog-dev libfmt-dev libpango1.0-dev libcairo2-dev meson gcovr
-```
-
-## Build
-
-Clone the repository and simply let meson do the heavy lifting.
 
 ```bash
+ptprnt --font "NotoMono Nerd Font" --fontsize 32 --text "🖶 ptprnt v0.2.0 🥰"
+```
+
+![Printed label that proudly reads 🖶 ptprnt v0.2.0 🥰](docs/assets/label_print_v0_2_0.jpg)
+
+## Quick Start
+
+## Quick Start
+
+**Binary dependencies**
+
+Arch Linux:
+```bash
+pacman -S pango cairo libusb 
+```
+
+Debian/Ubuntu:
+```bash
+apt install libpangocairo-1.0-0 libusb-1.0-0
+```
+
+**Build dependencies:**
+
+Arch Linux:
+```bash
+pacman -S libusb spdlog pango cairo meson
+```
+
+Debian/Ubuntu:
+```bash
+apt install libusb-1.0-0-dev libspdlog-dev libfmt-dev libpango1.0-dev libcairo2-dev meson
+```
+
+Note: spdlog is built as a subproject and statically linked, so it's not required as a system dependency.
+
+**Build and run:**
+Clone this repository first and enter the directory. Then build:
+```bash
+# Using the build script (recommended)
+./scripts/build.sh release
+builddir/ptprnt --help
+
+# Or manually with meson
 meson setup builddir
-```
-If you want to generate coverage reports, enable them via the command line switch
-```bash 
-meson setup builddir -Db_coverage=true
-```
-
-Rebuild by simply invoking ninja
-```bash
 ninja -C builddir
+builddir/ptprnt --help
 ```
 
-## Run
+## Usage
-Run the binary from your builddir
+
+### Basic Text Printing
+
+Print a simple label with text:
 ```bash
-builddir/ptprnt
+ptprnt --text "Hello World"
 ```
 
-## Test
+### Formatting Options
-Testing is done via gtest. To run your test simply invoke ninja with the "test" target.
+
+Control the appearance of your labels with these options:
+
+- `--font FONT_NAME` - Set the font (e.g., "NotoMono Nerd Font", "DejaVu Sans")
+- `--fontsize SIZE` - Set font size in points (default: 24)
+- `--halign ALIGNMENT` - Horizontal alignment: `left`, `center`, `right` (default: center)
+- `--valign ALIGNMENT` - Vertical alignment: `top`, `center`, `bottom` (default: center)
+
+**Example with formatting:**
 ```bash
+ptprnt --font "DejaVu Sans Mono" --fontsize 28 --halign left --text "Left aligned text"
+```
+
+### Multiple Text Elements
+
+You can add multiple text elements to a single label. Formatting options apply to all subsequent `--text` arguments until changed:
+
+```bash
+ptprnt \
+  --font "DejaVu Sans" --fontsize 32 --text "Large Title" \
+  --fontsize 18 --text "Smaller subtitle"
+```
+
+### Multiple Labels (Stitching)
+
+Create multiple labels that will be stitched together horizontally using the `--new` flag:
+
+```bash
+ptprnt \
+  --text "Label 1" \
+  --new \
+  --text "Label 2" \
+  --new \
+  --text "Label 3"
+```
+
+Each `--new` starts a fresh label. The labels are automatically stitched together with 60 pixels of spacing.
+
+**Example - Creating a series of address labels:**
+```bash
+ptprnt \
+  --font "DejaVu Sans" --fontsize 20 \
+  --text "Peter Lustig" --text "Am Bauwagen 1" \
+  --new \
+  --text "Donald Duck" --text "Blumenstraße 13" \
+  --new \
+  --text "Homer Simpson" --text "742 Evergreen Terrace"
+```
+
+**Example - Mixed formatting across labels:**
+```bash
+ptprnt \
+  --fontsize 32 --text "BIG" \
+  --new \
+  --fontsize 16 --text "small" \
+  --new \
+  --fontsize 24 --text "medium"
+```
+
+### Printer Selection
+
+By default, ptprnt auto-detects your printer. You can explicitly select a printer:
+
+```bash
+ptprnt --printer P700 --text "Hello"
+```
+
+List all available printer drivers:
+```bash
+ptprnt --list-all-drivers
+```
+
+### Testing with Fake Printer
+
+Before printing to your real printer, you can test your label output using the built-in fake printer. This generates a PNG image file instead of printing:
+
+```bash
+ptprnt --printer FakePrinter --text "Test Label"
+```
+
+This will create a file named `fakelabel_YYYYMMDD_HHMMSS.png` in your current directory with a preview of your label. Use this to:
+- Verify text formatting and layout
+- Test multi-label stitching
+- Preview before wasting label tape
+
+**Example workflow:**
+```bash
+# First, test your label design
+ptprnt --printer FakePrinter \
+  --font "DejaVu Sans" --fontsize 28 \
+  --text "Test Design" --text "Check Layout"
+
+# View the generated PNG file to verify
+# If satisfied, print to real printer
+ptprnt --printer P700 \
+  --font "DejaVu Sans" --fontsize 28 \
+  --text "Test Design" --text "Check Layout"
+```
+
+### Verbose Output
+
+Enable detailed logging for debugging:
+
+```bash
+ptprnt --verbose --text "Debug mode"
+```
+
+Enable USB trace to see raw USB communication:
+```bash
+ptprnt --trace --text "USB trace mode"
+```
+
+### Complete Example
+
+An example using a mixed bag of features:
+
+```bash
+ptprnt \
+  --verbose \
+  --printer P700 \
+  --font "NotoMono Nerd Font" \
+  --fontsize 28 --halign center --text "Product Label" \
+  --fontsize 20 --text "SKU: 12345" \
+  --new \
+  --fontsize 24 --text "Backup Label" \
+  --fontsize 18 --text "Date: 2025-10-16"
+```
+
+## Supported Printers
+(I need more printers for verification 😉)
+
+- Brother P-touch P700 series
+
+## Developer info
+
+This is a modern C++20 rewrite of [ptouch-print](https://git.familie-radermacher.ch/linux/ptouch-print.git). Credits to Dominic Rademacher for reverse engineering the USB protocol.
+
+**Build script:**
+```bash
+# Release build (tests disabled for faster builds)
+./scripts/build.sh release
+
+# Debug build (tests enabled)
+./scripts/build.sh debug
+
+# Debug with tests
+./scripts/build.sh debug --test
+
+# Debug with coverage
+./scripts/build.sh debug --coverage
+
+# Clean all build directories
+./scripts/build.sh clean
+
+# Show all options
+./scripts/build.sh --help
+```
+
+**Note:** Tests are only built in debug mode to keep release builds fast and small. Release builds do not include test binaries or link against gtest/gmock.
+
+**Running tests:**
+```bash
+# Using build script
+./scripts/build.sh --test
+
+# Or manually
 ninja -C builddir test
 ```
 
-Coverage reports can be generated via gcov if you enabled them (see Build section) by building the `coverage-text` target.
+**Coverage reports:**
+```bash
+# 1. Build with coverage enabled and run tests
+./scripts/build.sh debug --coverage --test
+
+# 2. Generate coverage reports
+./scripts/generate_coverage.sh              # All formats (html, xml, text)
+./scripts/generate_coverage.sh --html       # HTML only
+./scripts/generate_coverage.sh --text       # Text only
+./scripts/generate_coverage.sh --xml        # XML only (for CI/CD)
+./scripts/generate_coverage.sh --html --xml # HTML and XML
+
+```
