- Saved labels/receipts now show on one page instead of split across Shipping labels and Receipts, each with a badge for its type/printer, Edit (name+content, in place), Print, and Delete. - ZPL labels get a real visual preview via Labelary's public render API; ESC/POS ones show their raw content (no good general preview for that). - The Receipts free-text field only ever encoded whatever was typed as literal printable characters -- pasting mnemonic ESC/POS notation (ESC/GS/LF as command names, 0xNN as raw bytes) just printed as text instead of being interpreted. Added a small line-based parser for that notation (ReceiptBuilder#raw appends already-resolved bytes verbatim), verified byte-for-byte against an example with align/bold/barcode/cut.
labelprint
Unified UI for printing labels/stickers:
-
Native ZPL printing to a Datamax-ONeil thermal barcode printer
-
A proxy/switcher in front of three brother_ql_web instances, one per Brother QL printer
Routes
-
/— upload a PDF and print it (ZPL) -
/upload— upload form -
/test-print— print the bundled test label -
/brother— list of Brother QL printers -
/brother/<printer>/*— proxied to that printer’s brother_ql_web instance (UI and API alike)
Running
bundle install
bundle exec ruby app.rbRequires config.json (see printer definitions inside) and a .session_secret file (random string, not committed).
Deployment
Runs as sinatra.service (systemd) on rpi-printserver.local, under RVM (rvm default do bundle exec ruby app.rb — always uses whatever ruby is currently the RVM default, no manual bumping needed).
.gitea/workflows/deploy.yaml deploys on every push to main: SSH into rpi-printserver.local, git pull, bundle install, restart the service.
Dependency updates
.gitea/workflows/renovate.yaml runs Renovate on a schedule (Monday 06:00 Europe/Bratislava, or manually) to open PRs for outdated gems and GitHub Actions. See the "Dependency Dashboard" issue for current status.
