Remember that Acrobat comes with the base fonts (Helvetica etc.) built in, so even if you don't embed them, you can get conflicts with fonts on your system that have the same name but a different character set.

Some printer drivers have controls for substitution that you can turn off, but not all.

The 'fix' is, I'm afraid, to track down where the confusion comes from, and either install, uninstall, embed or unembed the fonts in question so both Acrobat and your printer driver have only one option as to where to go get it from (one of the reasons we use PDF/X, as it embeds everything). Acrobat handles the rasterization and it knows which is the right version of the font to use, as it's always the same one it used to render the screen image. Printing to an image stops the printer driver from loading anything, as it's just being sent pixels. As a non-standard lookup table by definition doesn't put the glyphs in the same places in the Unicode sequence, the substitute font prints 'correct' Unicode characters but it looks like garbage as it's printing a different glyph but it'll always be a 1:1 correlation.

However the embedded version in the PDF may look like the original, and may have the same name, but it can be encoded differently - this is why you see garbage.Įncoding fonts, especially Unicode, can use several methods - including non-standard lookup tables - and some printer drivers aren't able to read the more obscure encoding sequences, so will throw a bad font substitution. If a font with the same name is installed, the printer driver will either use the embedded one, or the installed one, depending on the settings in your printer software. If the driver likes what it's sent, it'll print using it - if not it'll substitute the 'damaged' font for something else, usually Courier or Times. If the PDF contains an embedded non-base font which isn't installed in the operating system, Acrobat will attach that font data into the Postscript stream sent to your printer driver. This is usually a conflict over Postscript fonts - not easy to fix and not always for a logical reason, but the issue is in where the font is coming from. I have seen several reports of similar problems by Googling, and it does not seem to be dependent on a particular printer or driver. It appears that the PDF is getting garbled somehow during download, but why would it behave in this odd way rather than just being completely screwed up?

If the PDF is saved and then opened in Acrobat 9, it will USUALLY print normally, but I recall in at least one case the saved version still printed garbled and I had to download another copy. If I print the document 'as image' it works fine but is very slow. Also, all graphics and text within graphics remain unaltered. The rest of the printout will be in this gibberish, except that from time to time it will revert for a line or two to the correct text. The gibberish actually follows a pattern: it is always printed in a sans-serif font, and ***each character is actually the next character up in the UNICODE sequence***. Note that this occurs when printing from Acrobat within Internet Explorer. When I print, the first page or two comes out fine and then it starts to produce gibberish. From time to time I get a paper that I want to print. I download a lot of PDFs of scientific papers from several journal publishers' sites. I have seen a similar problem numerous times over the last year or so. But I am hopeful that there is a solution that does not require purchasing a printer. They try to print to other printers and it works fine so my initial guess is that the issue is with the Brother printer (and updating drivers has not helped). They are using a Brother HL-5240 printer.

However, I have run into one that I cannot seem to fix. Most of the time, I have seen this with HP All-In-One printers and usually one of the above options seems to correct the problem. Short of buying a new printer and crossing our fingers, I am not sure what else to try. We have updated drivers, reinstalled Reader (yes the user is using the freebie), tried adjusting the limited settings available on Reader. to nail down the thing that causes it to go haywire. And it only happens occasionally and seems to be no consistency between the various documents in terms of format, fonts, content, etc. I support many locations and the conditions seem to vary slightly, but this latest one involves multiple page documents where the last page or two is filled with garbage but the pages before are fine. The display looks fine on screen, but when printing something is going awry.

When printing PDF documents, occasionally the printout will show garbage characters (like random letters, number and special characters) in place of the original text on the PDF. I looked in the forum but could not find any reference to this specific issue.

I apologize if this issue has been addressed.
