Jadens

Q1: What is localized printing?
A: Print documents stored on your mobile device directly to the PD - A4 printer via the app’s built - in Bluetooth connection, no internet required. Supported formats include PDF, Word, Excel, etc. Ideal for offline scenarios such as overseas warehouses and exhibition sites.

Q2: How to connect the printer?

• · Press and hold the printer’s top button until the indicator light flashes .
• · Open Jadens App or Print Go.
• · Tap "Connect Printer" within the app.
• · Select "PD - A4" from the device list.
• · Select documents and print (works on both Android/iOS).

Q3: File size and page limits?

Q4: Font display issues?

1. Why Fonts Need to Be Downloaded
   To protect your privacy, our app does NOT pre - install personal fonts (like custom or system - specific fonts) in its package. If a font is missing, your device will automatically replace it with system defaults (e.g., Arial).
2. Solutions for Missing Fonts
   • Embed fonts in PDF files before printing (most PDF editors let you do this).
   • Use universal fonts (e.g., Times New Roman, Arial) that work across devices.
   • For special/non - standard fonts, convert documents to image format (PNG/JPG) before printing.
3. First Launch Font Download Prompt
   When you open the app for the first time, you may see a prompt to “Download fonts” (e.g., calibri.ttf, msyh.ttc). This is the app’s font compatibility package—downloading it (takes 1–2 minutes, faster on Wi - Fi) ensures better font matching. Don’t worry—this doesn’t collect personal info; it just adds common font support!
   After the first download, subsequent launches won’t re - download these fonts.

Q5: Bluetooth connection fails?

• · Restart both the printer and your device.
• · Ensure devices are within 10 meters and unobstructed.
• · Delete existing pairing records in the app and reconnect.
• · Update Jadens App to the latest version.

Q6: Does it support iOS devices?
A: Yes, iOS users can follow the same steps as Android for seamless printing.

Q7: What are the device compatibility requirements?
A: For smooth performance with large files, we recommend using iPhone 7+ or devices with RAM ≥3GB. Please note that iPhone 6 and older models may crash due to hardware constraints, and there is no software - based fix for this issue. To enjoy full functionality, we advise upgrading your device.
