- All checks shown in one table by default (load all, no server-side printed filter) - Add payee search, date-from/to, and status filter controls to toolbar - Filtering is client-side; no extra API calls on filter changes - All checks get Edit/Delete buttons regardless of printed status - All checks get checkboxes for PDF selection - Remove separate Reprint button and reprintCheck function - Remove printed guard from PUT and DELETE endpoints
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)
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)
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):
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
- Select 1–3 checks from the ledger (checkbox column)
- Click Generate PDF
- A 3-up 8.5"×11" PDF opens in a new tab — three 3.5" check slots per page
- 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)
