# check-printing
|
||
|
||
Self-hosted web app for printing checks on blank check stock. A Dockerized Node.js web app accessible on the local network.
|
||
|
||
## Stack
|
||
|
||
- **Runtime:** Node.js 20
|
||
- **Framework:** Express 4
|
||
- **Database:** SQLite via `better-sqlite3`
|
||
- **PDF generation:** PDFKit with embedded GnuMICR E-13B font (GPL-2.0)
|
||
- **Frontend:** Vanilla JS, no framework
|
||
- **Container:** Docker Compose pulling from Docker Hub
|
||
|
||
## Getting started
|
||
|
||
### Production (Docker)
|
||
|
||
```bash
|
||
docker compose pull
|
||
docker compose up -d
|
||
```
|
||
|
||
On first launch, the app detects no account is configured and opens a **setup wizard** in the browser. Fill in three steps — checkwriter info, bank info, and account/routing numbers — then start entering checks.
|
||
|
||
If you have an existing ezCheckPrinting `.mdb` file, click **Import .mdb** instead.
|
||
|
||
### Development (local)
|
||
|
||
```bash
|
||
npm install
|
||
npm run dev # nodemon src/app.js
|
||
```
|
||
|
||
## Importing from ezCheckPrinting (.mdb)
|
||
|
||
Two ways to import:
|
||
|
||
**Via the UI (recommended):** Click **Import .mdb** in the toolbar, select the file, and click Import. The server runs the migration and shows the log output.
|
||
|
||
**Via CLI** (inside the container or locally with `mdbtools` installed):
|
||
|
||
```bash
|
||
docker exec -it check-printing node migrations/import-mdb.js \
|
||
--file "/app/data/YourAccount.mdb"
|
||
|
||
# Preview without writing:
|
||
node migrations/import-mdb.js --file YourAccount.mdb --dry-run
|
||
```
|
||
|
||
The script imports account config (T100), logo (Settings), check layout (T200), and check history (T104).
|
||
|
||
## Printing
|
||
|
||
1. Select 1–3 checks from the ledger (checkbox column)
|
||
2. Click **Generate PDF**
|
||
3. A 3-up 8.5"×11" PDF opens in a new tab — three 3.5" check slots per page
|
||
4. Print from the browser; checks are marked as printed in the ledger
|
||
|
||
Use the **Reprint** button on printed checks to regenerate without re-marking them.
|
||
|
||
## Check layout
|
||
|
||
- Page: 8.5" × 11", zero margins
|
||
- Three check slots of 3.5" each; remaining ~0.5" is tear-off strip
|
||
- MICR line at 0.267" from bottom of each slot
|
||
- MICR format: `A{routing}A {account}C {checkNo}A` (GnuMICR E-13B encoding)
|
||
|
||
|
||
## Environment variables
|
||
|
||
The app has no required configuration. These are set in `docker-compose.yml`:
|
||
|
||
| Variable | Default | Description |
|
||
| -------- | ------- | ----------- |
|
||
| `PORT` | `3000` | HTTP port |
|
||
| `DB_PATH` | `/app/data/check-printing.db` | SQLite database path |
|
