B4J Question Zebra ZXP Series 7 – Text Not Printing When Using WebView (Only Images Are Printed)

[afields22]

Hi everyone,

I am using a Zebra ZXP Series 7 card printer to issue staff ID cards.
For this purpose, I have developed an application that not only manages the staff database but also handles card printing.

The process:
- The card design is based on an HTML template.
- The HTML is rendered in a WebView, and then sent to the printer using the code below.
The issue:
- Printing works perfectly for images.
- However, any text elements present in the HTML are not printed at all.
- This issue only occurs in this staff card program; when issuing student cards (using a different program, but the same printer and HTML/WebView workflow), everything prints as expected, including text.

My question:
Is there any parameter or configuration (either in the printer, the OS, or B4J) that could now be required to enable text printing?
Has anyone faced a similar issue with WebView printing or Zebra printers?


Code used for printing:

Dim P As Printer
P = GetPrinter("Zebra ZXP Series 7 Network Card Printer")
If P.IsInitialized = False Then
    Log("Zebra printer not found.")
    Return False
End If

Dim paper As Paper = P.GetPrinterAttributes.GetDefaultPaper
Dim pl As PageLayout = P.CreatePageLayout(paper, PageOrientation_Static.LANDSCAPE, 0.5, 0.5, 0.5, 0.5)

Dim PJ As PrinterJob = PrinterJob_Static.CreatePrinterJob2(P)
PJ.GetJobSettings.SetPageLayout(pl)

'Dim joWV As JavaObject = wv
'Dim engine As JavaObject = joWV.RunMethodJO("getEngine", Null)

Dim WVJO As JavaObject = wv
WVJO.RunMethodJO("getEngine", Null).RunMethod("print", Array(PJ.GetObject))

Additional info:

- The workflow and code are almost identical in both staff and student card programs.
- Only the staff card app is showing this text printing problem.
- The HTML preview in WebView looks correct (both text and images display).
- Tested with different fonts and simple HTML (no improvement).

Any advice or suggestions would be greatly appreciated!
Thank you in advance.
