How to Preserve Bold Fonts When Printing PDFs with VeryPDF PDFPrint Command Line

Posted on Author VeryPDF / 108 Views

At VeryPDF, we are always grateful for the support of our loyal users. We recently received an inquiry from a dedicated user who encountered an issue when printing PDF documents using the pdfprint method with the useembedfont parameter. Despite enabling this setting, the printed document did not reflect the bold effect of the fonts in the original PDF; all text appeared with the same thickness. Since their usage scenario was urgent, they sought a solution to ensure that the printed output matched the PDF's original font thickness.

How to Preserve Bold Fonts When Printing PDFs with VeryPDF PDFPrint Command Line

Understanding the Issue

When printing PDFs, font rendering can sometimes differ depending on how fonts are embedded and processed. The useembedfont parameter helps ensure that the printer utilizes the fonts within the PDF, but certain font effects—such as bold—may not always transfer correctly. This discrepancy can be due to the printer's font handling capabilities or the way the PDF is structured.

Solution: Use the -raster2 Parameter

To address this issue, we recommend adding the -raster2 parameter to the command line. This setting converts the document to a raster image before sending it to the printer, ensuring that all font styles, including bold effects, are faithfully reproduced in the printed output.

Suggested Command:
pdfprint.exe -raster2 D:\test.pdf
Why -raster2 Works

The -raster2 parameter will render all PDF pages to image files within the Windows system first, and then print these images to the printer. This process eliminates inconsistencies caused by printer drivers and ensures that the printed document accurately represents the original PDF, including the bold effect and other text attributes. Since the text is transformed into a high-quality image format before printing, any font rendering issues related to printer font substitution or processing differences are completely avoided.
