Suddenly my printer won't print in duplicate mode/flip on long edge but prints with one side the reverse of the other. That doesn't happen with Chrome or Edge. Anyone know what has changed/how to fix it?

Soluzione scelta

I tried this about:config / duplex / change 1 to 2 described here with my EPSON TS702 dot matrix printer. IT DID NOT WORK. Gmail still prints the 2nd pages upside down from Firefox ever since a very recent version in the last week or two of Firefox. That version changed the dialog window when you print emails from gmail and it has not printed correctly ever since. It worked fine before that version change which came with the new printing dialog box. THIS DOES NOT OCCUR WITH CHROME BROWSER which still prints gmail messages correctly. I have switched to using CHROME for gmail and probably soon will switch entirely to the CHROME browser if Firefox does fix this problem soon as it makes printing email messages impossible, no matter what you select to try to avoid it. Again, the fix suggested here DOES NOT WORK for me. THE NEW FIREFOX SOFTWARE HAS THIS BUG. Thank you. Jeff Weiss

That is an issue with print*duplex prefs that have been set to 2 instead of 1 on the about:config page.

You can try switching the short-/long-edge binding manually:

(1) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button accepting the risk.

(2) In the search box in the page, type or paste duplex and pause while the list is filtered

Firefox should list the print_duplex value for each printer. Printers you have not yet used in the new print experience will have a weird number that is not on this list:

  • 0 => print single-sided
  • 1 => print double-sided, with long-edge (portrait mode left-right) binding
  • 2 => print double-sided, with short-edge (portrait mode top-bottom) binding

To edit a value, double-click the current value to display an editing field. Change it as you wish, then press Enter or click the blue check mark button to save the change.

If you make the change there, does it "stick" or does Firefox switch it back after the next time you print?

Hi Jeff, 2 is upside down when you print in portrait orientation (short edge binding); change it to 1 (long edge binding). Or maybe that is what you did?

The about:config tab_mo didn't solve the issue. About:config / duplex as described by jscher2000 did. What I can't figure out is why some of my printers show a 4-6 digit number instead of 0, 1, or 2. Thanks jscher.

jscher2000- This is a nightmare. I had found my Epson printer was set to 1 and changed it to 2 (which did stick) but when I just changed it back to 1 per your message, it now printed from MS Word the second page correctly. At the same time I changed the two other printers (Adobe pdf and MS to PDF) that appeared from 1 to 2. So I changed them back to 1. NOW ADOBE WON'T PRINT AT ALL a document which I printed successfully yesterday with the same font. Instead, I get the log file from Adobe saying:

%%[ ProductName: Distiller ]%% Calibri-Bold not found, using Courier. %%[ Error: invalidfont; OffendingCommand: xshow ]%% Stack: -dict- -file- %%[ Flushing: rest of job (to end-of-file) will be ignored ]%% %%[ Warning: PostScript error. No PDF file produced. ] %%

I changed Adobe back to 2 and then back to 1. In all cases, Adobe now gives the same font error (and I tried several different fonts and it still won't print. Note the original successful printing had this font with no problem. So I've managed to screw up printing from Word to PDF -- almost as important to me as being able to print to my Epson printer. Nightmare is the only word for this.

I wish I never started messing with about:config and ignoring the message about proceeding at your own risk. Any idea what setting Adobe PDF wants, or did I just permanently disable it?

Hi Jeff, these are Firefox settings in about:config, and as far as I know, they should not affect other applications.

I don't know whether you need to set duplex with a PDF printer. Probably best to leave the preference for those printers on 0 (zero, for single-sided). You also can expand the "More settings" and uncheck the box for "Print on both sides".

As for --

%%[ ProductName: Distiller ]%% Calibri-Bold not found, using Courier. %%[ Error: invalidfont; OffendingCommand: xshow ]%% Stack: -dict- -file- %%[ Flushing: rest of job (to end-of-file) will be ignored ]%% %%[ Warning: PostScript error. No PDF file produced. ] %%

-- I don't see a connection between duplex printing and fonts, so I suspect that is a different problem.

The Adobe PDF printing options look normal, but the PDF files that it creates can no longer be opened by Adobe Acrobat or Reader. Double-clicking on the PDF file it creates, I get "There was an error opening this document. This file cannot be found" even after double clicking on the file with the latest Adobe Reader CC that I downloaded and installed. Test print files it creates can be opened but have screwed up fonts. It just looks like Adobe PDF printing has been completely hosed somehow. I agree at this point, its probably beyond the about:config duplex changes since it is single sided printing, but I changed nothing else in my system before this happened. I should never have started changing those duplex settings for Adobe PDF.

Thanks for your help. I'd not thought about using another browser and will try it!

Jeff, let's dig a little deeper. Are the Acrobat documents you are trying to print documents that you printed to Acrobat from within firefox, or documents that you obtained without Firefox (i.e., by printing to Acrobat from a word processor or directly from sources other than Firefox?

RJAR, et al.- I'm trying to print to Adobe PDF as printer from Microsoft 365 Word Enterprise version, although its a few years old and not supported any more. However, this problem now looks to me like it's some kind of font problem for Adobe PDF printer that was triggered somehow by my touching the duplex settings in Firefox -- however unlikely that sounds. I can get it to print successfully to Adobe PDF from MS 365 Word if the document has certain fonts (Courier New) and not others (Calibri) which make it go haywire as described above. I'm now working with Adobe on this (one of their PDF experts is a local friend of mine and I'm expecting a phone call at some point to go through it). Hopefully, he can figure out how to restore Adobe PDF printing for me. Sorry if I sounded pretty short here. Thanks for trying to help but any ideas suggestions still much appreciated. -Jeff
