PDF Warning Internal Error 00 invalidfont

[danielr74939812]

Macbook Pro 15.7.2 with HP Laserjet Pro MFP 4101dfw and HP Laserjet Pro M428f.

When I try to print some PDFs (not all), it acts like it is going to print but the page that comes out of the printer only says this:

PDF Warning

  Subsystem: PARSER

  Warning: InternalError 00

  Error Information:

        Reported by PDL PDF

        invalidfont

No errors given in printer logs. As far as the computer/printer is concerned, it printed the documents just fine.

I have spent hours on the phone with HP thinking it was a printer/driver issue, and they've concluded that it is an Adobe Acrobat issue since I can print it from other PDF programs and Preview. It also prints "as image" in Acrobat, but that ruins the formatting as I need it to print actual size on the page. I uninstalled/reinstalled printer and Acrobat multiple times. Does anyone have any suggestions on where I can go from here to resolve this issue?

Also, these documents used to print just fine. This started a couple of months ago.

@danielr74939812 the title says it...'invalidfont' —there is an issue with one of the fonts. I would double check and update the Mac Printer Sriver. Look for a recent dedicated macOS driver for the MFP 4101dfw and M428f (not a generic PCL driver.) The two main printer protocols are PCL and PostScript (PS). The invalidfont error is usually a PostScript interpretation error. Go to System Settings - Printers & Scanners. Delete your current HP printer entry. Re-add the printer and try to select a different driver or protocol during the setup (e.g., if you are currently using the generic Apple PS driver, try to find a specific HP driver, or vice versa). And make sure the fonts are embedded. Better yet, look at the properties of the PDF and see what fonts are being used too. Maybe, it's a weird font?

Thank you for responding. I have already uninstalled/reinstalled the printer with different drivers multiple times while working with HP support but with no success. The same PDF prints fine on a Windows machine with Acrobat Reader to this same printer which is why HP concluded that it must be a software issue and told me to contact Adobe. It would be nice if the error message told me WHAT font is giving it a problem, as I've also checked the font list for the PDFs that give me problems and I don't see anything unusual there that isn't in another form that does print.
