Printing problems with High Sierra

OK! I've found a consistent pattern with my WF-3640. After I recreate it using the CUPS interface it works fine UNTIL the unit goes to sleep. After that I will get a 'filter failed' if it is in that state. If I wake it up it will work again. So the software is not making the printer come alive and I suspect that I could add the printer again normally (without using CUPS interface) and as long as the printer is awake it will print.

Now to investigate why its not making the beast stir...

1) Remove the Epson printer from the list of printers in Settings/Printers

2) Download the Epson Software updater from Epson's site (https://epson.com/Support/sl/s select your printer, then go to Utilities and download the Epson Software updater.

3) Run the updater.

4) Add your printer back in Settings/Printers.

Ok! My previous posts seem to indicate I had solved the problem each time but problem kept coming back after a few prints. However after doing some more searching I found this link. https://epson.com/Support/wa00720

I followed the linked procedure on the 4 other macs in the house that had experienced the problem (but hadn't been worked on). Worked instantly after having made this change.

In essence:

Go to System Preferences>Sharing then copy your computer name from the appropriate box e.g. "Bobs Computer"

Go to System Preferences>Printers and Scanners and click on your printer. Click the "Options and Supplies" button. Paste in the computer name from above in to the Location box.

Close out of your System Preferences and print! (One hopes...)

Good luck!

I have exactly the same problem and - sorry - no solution so far. I tried all solution proposals posted in this thread.

The printer model is EPSON PX730WD, iMac mid 2011, macOS 10.13.1

Printing via IOS or Windows works fine.

Is there anyone, who has a running PX730WD (AirPrint or Ethernet connected) and macOS 10.13.1?

Same situation here, iOS printing is fine, macOS 10.13.1 fails on "finding printer" as did the 10.13.

The printer Epson PX730WD is connected to the WiFi router via LAN the Mac and all other devices trough WiFi.

Also the printing from WIN10 is without problems. The second printer a Brother bw laser, connected in the same way is printing from all OS without any problem

Not working.

I removed the printer, reset the whole print system and reinstalled the Epson Stylus Photo PX730WD.

The printer in the print manager is Idle (green mark) pushing printing immediately change to In Use (yellow mark)

and when the file was sent to printer changes to In Use (yellow mark).

The feedback is Printing - Looking for printer and then -Communication Error -

I was a little confused about the macOS versions. TODAY I could install 10.13.1 (release in Germany) and now the printer works.

Here‘s what I did:

1. update to version 10.13.1

2. delete all files in the directory ...library/printers/ (as described in Apple Support)

3. add a new printer in the system preferences. I followed your advice not to install the Airprint driver, but the EPSON PX... thing.

4. printer works again, thank you!

I found the solution and it works - at least with Epson PX730WD.

* in the WiFi router assign a fixed IP address for the printer.

* install the printer from the IP tab inputing the assigned IP address and select the PX730WD software.

* restart the router, the printer and all machines.

* done!

As you can see from my previous post, the "standard" installation had a problem to find the printer

(although the scanning was OK). Maybe this should be reported to Apple to take action...

The printer drivers are contained in macOS, no need to download & install single drivers (basically, apart of the problems mentioned above). New driver software comes along with system upgrades via App Store.

It does not work wirelessly, only via a USB connection. You probably wrote to me that there is no software on Apple's servers because I deleted everything from the (library-printers) folder, resetting from TimeMachine's backup, but it does not work.

I had a similar problem. My Cannon MG4120 was not being seen by my updated mac. All my computers access my printers from our wireless network. the computers that had not been updated to macOS High Sierra 10.13.1 had no trouble printing from the Cannon. Turns out the problem was that in the process of upgrading the new OS set my network to generically "xfinity" which is our provider. My home network on xfinity has a different name of course. Once I switched to the correct network all was fine.

I have the same printer but it is not listed in the drivers. Neither can I find a suitable installer from EPSON and the one I can find for a previous OS is not recognised as from a 'trusted source' and will not install, anyway.

It seems that neither Apple nor EPSON are remotely interested in resolving this problem.

I had te same problem with my MacBook Pro (High Sierra) and my Epson PX730WD.

EPSON Technical Support here in France sent me a link which solved it.

See what you can do with it.

Thank you so much! I installed the Epson software updater (as per your link), ran it, ran it again, ran it a third time until it told me my software was 'up to date'. Tried printing (from Photoshop), printer window showed 'Printer not connected' (as usual, though I had already reconnected it to the WIFi router and scanned successfully via WiFi), paused printing, restarted printing and bingo! Image printed successfully. Printed another. Set off another to print. Went off to declare to the world, problem solved! Returned to find: 'Printer not connected' again. Paused printing, restarted printing, rinse and repeat and yes, eventually, the third image printed as well. So, not fully solved but maybe halfway there. Maybe a bit more than halfway. I'll keep you posted. Thanks again.
