No response

Additional Information

• Using Epson printer model M-T500II series https://www.epson.co.nz/pos/products/Printers/DisplaySpecs.asp?id=M-T500II.
• Work just fine with Electron 24.8.8 and below with silent set to true.
• Work just fine with Electron above 24.8.8 only when silent set to false -> not expected, I'd like to keep it set to true.
• It missed out all non left-aligned text with Electron above 24.8.8 (tried several version on 25.x.x and 30.x.x and 31.0.0-alpha.2).
• I have tried without luck the workaround mentioned in [Bug]: Silent print was incorrect paper layout with webContents.print, but layout was correct when I use print dailog #39179 by adding dpi:{ horizontal: 203, vertical: 203 } (203 is the default printer resolution).
• Expecting the issue gets fixed in 31.0.0-alpha.2 but not in my case.

Hello @iam-ben. Thanks for reporting this and helping to make Electron better!

Would it be possible for you to make a standalone testcase with only the code necessary to reproduce the issue? For example, Electron Fiddle is a great tool for making small test cases and makes it easy to publish your test case to a gist that Electron maintainers can use.

Stand-alone test cases make fixing issues go more smoothly: it ensure everyone's looking at the same issue, it removes all unnecessary variables from the equation, and it can also provide the basis for automated regression tests.

Now adding the blocked/need-repro Needs a test case to reproduce the bug label for this reason. After you make a test case, please link to it in a followup comment. This issue will be closed in 10 days if the above is not addressed.
