OKI 710DN Laser Printer Filter Failure on Mac OS Catalina

Here’s something anyone with an Oki printer can try:

1. Go to Oki’s website, look for drivers for your printer.
2. Choose Linux as your operating system. (Yes I know Mac OS is not Linux. Bear with me).
3. Download the file described as "PPD file".
4. Add your Oki printer as new; when prompted for your driver file, choose the .ppd.gz file you downloaded in (3) above.

Works in Mojave, and gives access to most, if not all features. Haven’t tried Catalina but I suspect it’ll work fine.

If you have another device that you haven't updated yet, you can possibly use Bonjour to print through the pre-Catalina device (I am successfully doing exactly that). Otherwise I think you'll either have to revert your entire system to Mojave or wait until Nov/December for OKI to update the drivers. It's not the printer driver itself - it is fine - it's one of the files that the driver accesses.You 'should' have been getting messages for the past year that the OKIPSPlugin filter would not be compatible with the new OS. I got this about every two months for the previous year.

Same here, I have an MC873. Filter failure. Log says:

Oct 10 12:18:15 ottoman com.apple.RemotePDEService[10816]: objc[10816]: Class OnlyIntegerValueFormatter is implemented in both /Library/Printers/OKIDATA/PDEs/OKIPSColorOpt.plugin/Contents/MacOS/OKIPSColorOpt (0x10fc55100) and /Library/Printers/OKIDATA/PDEs/OKIPSPrtOpt.plugin/Contents/MacOS/OKIPSPrtOpt (0x10fcd3800). One of the two will be used. Which one is undefined.

Wow, on the Japanese OKI site they have a November - December target for the OKI compatible printer drivers! WTF! A year time to prepare was not enough for them! We updated many computers before finding this out, this is really crazy!

As a temporary workaround I found that the generic PS driver works! Douplex works, but I can not use the different paper trays. But hey, at least I can print something!

While the printer driver may be 64 bit, files that it uses may not. I've been getting warnings for my C942 that the OKIPSFilter.plugIn is not optimized for my Mac and needs to be updated. This software will not work with future version of the Mac OS (Catalina). I'm currently installing Catalina on a temporary partition to test it, but we might have to wait for OK Japan to fully update their printer drivers.

gnaegi - Thanks - I can live with that (if they meet that deadline). Looks like mine is set for Mid Nov. The lack of tray selection is a deal killer for the interim.

When I print from my MacBook Pro I access my OKI using Bonjour - I wonder if I can upgrade that to Catalina and keep my iMac pro on Mojave and print from the MBP?

In my case bonjour did not work neither which I find strange. I though the bonjour way would be some kind of generic printer driver similar to the generic postscript driver. It could be that it only fails when the native OKI driver is installed as well, but this is just an assumption. In any case, the bonjour driver im 10.14 did not give me access to the different trays and I could not use the toner saver options why I installed the native driver.

I have the same problem here with a OKI c511 dn.

I can't even install it as a generic printer, since the OKI driver is automatically selected.

Luckily I have a Kyocera b/w printer still working, so I can at least use that one.

Really annoying...

@Edd84: you need to set it up a new printer. In that dialog you can select the driver manually. Once done it is not possible to change the driver to something else. You don't need to delete the old configuration if you want to keep it, you can have to different printer configurations for the same printer, no problem.

You must add a new printer. When it detects your OKI it normally suggests using the Bonjour driver. But this is a drop down where you can select all compatible drivers. Select the generic PS driver from that menu. Once you set up a printer you can not change the driver, however you can have the same printer in two configurations without any problems, just give it a name e.g. "oki workaround" or something ;-)

Snap! Just installed OS Catolina 10.14 to allow the updated "reminders" function to sync across my devices as I now get the

"filter failed" message

I've tried reinstalling the printer driver compatible with Mojave 10.14 but still the same message. I've emailed OKI support but no response so far...

Any suggestions on how I can print?

Thanks for your response all be it disappointing. I did not receive any error messages and my i-pad automatically updated to Catalina, otherwise I would have left it on the current operating system. I would have to revert the update for 3 devices so not sure I have the time to do that right now. Roll on December... How frustrating!

I don't have an option to install a generic printer, so my OKI is definitely not working at all in my office.

Since I have other software problems (time machine not working, VirtualBox crashing, and others appearing day by day) I am about to downgrade to Mojave with a clean installation, even if it's so disappointing.

I always upgraded the OS as soon as possible, next time I will wait at least 2-3 months after new release.

Take a look at this English site - https://okiprinting-en-gb.custhelp.com/app/answers/detail/a_id/29123

I have just downloaded the Printer Driver Updater (PS) referenced in the document and I can now print from Catalina

Had same issues.

Just updated driver from OKI. Now appears to work!
