C-Lodop on Chrome / HTTPS: Checklist & Parallel Path

In some environments, a Chrome upgrade, HTTPS (e.g. :8443), or a stopped local service can mean print does nothing. Start with the Lodop vendor checklist—this is not a claim that C-Lodop is defective—then see when to PoC web-print-pdf alongside Lodop without uninstalling it. Selection: Lodop comparison; steps: parallel guide.

How to read this page

C-Lodop is one browser-facing deployment pattern in the Lodop ecosystem—stable deployments need not change because of this page. We do not evaluate Lodop as a product; we help with environment checks and parallel options.

What each approach is

C-Lodop / Lodop

C-Lodop bridges browser pages to Lodop printing—common in legacy OA/ERP/logistics apps. Calls go through the LODOP object and local services; version requirements per Lodop vendor docs.

Web Print Expert + web-print-pdf

web-print-pdf uses a local WebSocket client (Windows/macOS/Linux/domestic) with standard npm printHtml—a standard Web page plus desktop service model. See live demos.

Common symptoms & checks (reference)

These symptoms often appear after Chrome/Edge upgrades or HTTPS policy changes—follow Lodop/C-Lodop official docs and your IT policy; this list is a reference checklist only.

SymptomPossible factors (reference)Suggested checks
Print button does nothingC-Lodop service stopped; port conflict; script not loadedVerify local C-Lodop service; check console errors; compare with vendor install guide
Some PCs act up after a Chrome upgradeService/control vs browser policy (per vendor docs)IT checks Lodop vendor version notes first; parallel PoC only for new modules if needed
HTTPS mixed contenthttp assets; ws vs page protocolFollow vendor HTTPS deployment notes; review proxy/CA policy
Only some PCs failInconsistent client versions; firewallStandardize images; log environment diffs
  1. Record browser version, C-Lodop service version, HTTPS or not
  2. Compare console/service logs on failing vs working PCs
  3. For new modules, PoC HTML print via parallel guide
  4. Keep Lodop for precision overlays until HTML assessment completes

Where web-print-pdf fits

  • Modern browsers: current Chrome/Edge with standard Web stack
  • HTML/CSS templates aligned with Vue/React reports
  • Silent + named printers via local client
  • Cross-platform npm API across Win and domestic Linux desks
Keep C-Lodop/Lodop for unmigrated overlays; parallel PoC web-print-pdf for new modules or browser-upgrade reviews—see parallel guide.

How related guides fit together

Choose by scenario

Keep C-Lodop

Overlay templates unchanged

Maintain Lodop DSL and C-Lodop services; IT aligns browser versions with vendor docs.

Parallel PoC

Browser upgrade / new HTML modules

PoC HTML + printHtml for new modules; legacy forms stay on Lodop—see parallel guide.

Hybrid

HTML reports, Lodop labels

Move A4 reports in parallel; evaluate precision overlays case by case—Lodop may continue.

FAQ

C-Lodop vs Lodop?

C-Lodop bridges the browser to Lodop capabilities. web-print-pdf is a separate npm + client stack you can evaluate in parallel.

Print broke after Chrome upgrade?

Use the checklist on this page and Lodop vendor docs. Parallel PoC web-print-pdf for new modules—see parallel guide.

Swap to printHtml without template changes?

No drop-in Lodop API replacement—prepare HTML/CSS or phased parallel rollout; keep Lodop templates until reviewed.

vs Lodop comparison page?

Lodop page = overall selection; this page = C-Lodop environment & Chrome checks.

Must we stop using Lodop?

No. Stable Lodop/C-Lodop can continue; web-print-pdf suits new modules or parallel PoC—rollback by disabling the parallel flag.
