A PDF attached document may sometimes show an error titled invalidfont when you attempt to print it with Adobe PDF viewer or any other software. This is due to the fact that the file format is invalid. Generally, it occurs when the files are incorrectly configured and when the PDF viewer is outdated.

What causes an Invalidfont printer error?

What causes an Invalidfont printer error?

There are a number of reasons why invalid font errors occur, but of course, they are always related to fonts. For example, an invalid font name or an incorrect font dictionary can cause these errors. When newer fonts (like OpenType fonts) are sent to a slower RIP, they may also result in incorrect fonts in the output.

I am using BIRT 2.2 and the provided servlets to print a report directly on the server. The report in question has a barcode implemented as a font. I’ve managed to get the viewing servlet to output the PDF with the barcode showing up fine. However, the postscript generated by BIRT won’t print on any postscript printer I’ve tried (Xerox Workcentre 5050, HP 9000). The Xerox prints out a Postscript error message (invalidfont), the HP dies completely, displaying a “Service Error” on the LCD. I can see the commands in the generated Postscript to embed the font and use it, but I don’t know enough Postscript to say whether it is valid or not. I can view the file properly using Ghostscript/Ghostview on Windows. I also tried the BIRT 2.3 report designer and chose Preview as Postscript and printed that, same results, though the PS file does look different.

Invalidfont, on the other hand, is a PostScript error that occurs frequently with Level 3 PostScript when sent to printers that are only capable of handling Level 2 PostScript.

Depending on the cause of the printer error, you may be able to correct the problem using some of these methods.

There are many reasons why an error could occur with an incorrect font in Windows printers, so we have compiled a comprehensive list of fixes to help resolve this issue.

After upgrading from Catalina to Big Sur, I’m experiencing printing issues. The error shows “:invalidfont. Offending command:show”. My printer has a PS card. Reinstalling the driver didn’t solve the problem. The issue was not occurring before I updated to Big Sur. In addition, I’m curious why it’s still the same version 1.3 after updating the new driver (version 1.8). How can I update a Mac OS driver properly?

From 5 users I have identified as being affected by this issue, the only common denominator seems to be Big Sur. I have been experiencing the same issue too. I have seen it most often when printing from Google PDF or Gdoc, but I have seen it also happen when printing from Adobe and the system print menu. I have not tried the update 11.2.3 yet. Perhaps that contains the fix?
