Unexpected Acrobat DC update errors when printing from Firefox

[casinclaire]

A notice flashed on my screen today that said Acrobat Pro DC had been updated and that a system restart was required to use it. I ignored it at that moment because I wasn't ready to print anything, then forgot about it until I tried to print from Firefox and got the following: 

%%[ ProductName: Distiller ]%%
Lato-Regular not found, using Courier.
%%[ Error: invalidfont; OffendingCommand: xshow ]%%

Stack:

%%[ Flushing: rest of job (to end-of-file) will be ignored ]%%
%%[ Warning: PostScript error. No PDF file produced. ] %%

Oh, yeah, that update thing ... so I rebooted. But I'm still getting the same message. I can actually open Acrobat Pro DC, and I can print to it from my regular softwares; but from Firefox, I'm getting this error message, and I do a LOT of printing from Firefox, so I need this solved. Anyone have any ideas? Thanks much in advance.

Am I correct to understand you are printing to paper from Firefox, but you are receiving a Distiler error message instead?

No. I'm attempting to print a regularly received receipt from my email to
a PDF file, for filing purposes, which I do multiple times daily.

However, here's an update: When I posted the question, I thought it was a
Firefox-wide printing problem. I have, though, only just this minute
discovered that any other email I choose will print to PDF from Firefox
without a problem, and it appears the problem is with this one specific
receipt, which is very odd as it is just this month's version of the same
thing I've printed every other month in past without a problem. Because
it's never been a problem in the past, I didn't imagine this vendor's
receipt was the source of the problem now. But it does appear that this
might be a vendor problem rather than a Firefox problem.

I will mark my own response as the correct answer just so no one else
wastes any time on this. Thanks so much for being on top of things, though,
and responding so quickly. If the problem emerges again with some other
print attempt, I'll be back!

Firefox has nothing to do with Acrobat Pro DC in this regard.

But out of curiosity, is this happening also with any other web browsers?   

And the main question is, did this problem still manifested after a restart?   Every update always requires restarting a computer (at least on MS Windows, mostly).

Because if that's the case then it really deserves attention from Adobe.

Unless you were using the Acrobat PDF Maker extension in Firefox, for which Mozilla discontinued its support,  I don't think there's a lot that Adobe can do about that.

If you had that extension before in Firefox, and you also updated Firefox, that extension is not supported by Mozilla anymore until further notice.  You'll need a Chrome-based web browser like the new Micrososft Edge web browser, Chrome web browser, and / or Internet Explorer 11 to be able to use that extension.

However, that doesn't seems to be the issue on your end.  I just added that info to rule out what could be wrong.

In my humble opinion, I think the problem was that you have set your default printer to Adobe PDF in your operating system, or , you manually chose that printer option from Firefox.

If yes, consider that using Adobe PDF as default printer uses UTF-8 for character encoding. And if you're on a MS Windows 10 machine, windows supports UTF-16 for character encoding natively. This means that a lot of API's will have to translate back and forth between UTF-8 and UTF-16 character encoding between applpications. If you didn't restart after the update took place, this could've triggered the problem.

If my suspicion is correct :

• If  you're using MS Windows 10, compare with the  release notes which version are you using and force  a manual  update again, specially to the latest Win10 version (it is still free to get if you haven't done so): https://docs.microsoft.com/en-us/windows/release-information/

• Also see slide below. Check if by disabling the option that I pointed out for you resolves the printing issue with  Firefox. A restart is required after you deselect that option.

Please ignore my long reply.

Seems that we were typing at the same time.

Now I feel really dum after posting all of that unnecessary geeky vomit.

Hey, don't feel dumb. I'm grateful that anyone even replied! Besides, that
was all very interesting info and I'm saving it. I'm always up for learning
things, and I recall similar problems that your info might very well
pertain to if they ever come up again.

Just to let you know, I'd just replied the below to you but I don't think
it went through. (If it did, then I'll be batting a 1000 today for
duplicating my own replies! LOL).

*What I wrote .... *

Thanks for all the info.


- To be clear, I'm doing nothing I didn't do just fine yesterday.
- Yes, I rebooted after the update.
- I'm using the Adobe PDF driver, not a Firefox or any other type
plug-in.
- Per my latest post (which perhaps you haven't seen), all other
documents except the one I was having problems with seem to be printing
fine out of Firefox.


I think this was just a weird aberration, and if it doesn't flare up again,
I won't sweat it. But I'll keep in mind all that you have written, as that
was a lot of info I did not know! I appreciate it! Thanks much.

Don't feel dumb by any means. At least you KNOW the geek stuff. I was shown
up as a bit of a dunce by just one nonprinting receipt when all the rest of
them printed just fine, if I'd only thought to try them before I posted.
Instead I thought I had a program-wide problem when I didn't, LOL. Duh and
duh!
