Mojave/Lightroom/Epson P800 issue: print job "aborted"
« on: April 18, 2019, 06:53:05 pm »

I know that Mojave is not kind to printing. And Epson is not quite up on things all the time.  That all said, this one was strange.

Versions, etc.: Mojave (10.14.4), Epson P800 (10.16) connected over wireless.

Task Details: Printing 25 "contact prints" (3x2 -- 5 rows of 5 images, landscape) to (one page) A3+ (13x19) paper (HahneMuhle, glossy, if it matters) from Adobe Lightroom (most recent CC Classic version).  Printing B&W prints, so Lightroom told to let printer manage color, and printer set for Advanced Black & White mode.  16-bit on.

Situation:
  • Last week -- worked fine, as expected.
  • Last night (with no software change):  Lightroom churns for a while building print job.  While this is going on, print queue shows job as "incoming" (normal).  When Lightroom is nearing the end of its work (but not yet done), the print queue window appears to think it should start printing (shows job as printing 1 of 1 or whatever).  When Lr finishes, job is instantly converted to "Aborted".  Looking at error log & console log, it has a "client error" indicating that no files were available.

Resolution?
  • Rebooted to no avail
  • Reset printing system to no avail (but high annoyance  >:( ).
  • On the theory guess that it was dropping out early for some reason, I tried cutting down the number of "contacts" (still just 1 A3+ page). 24 contacts -- same, 23 -- same, 20 -- it works fine.

Question:  Is there some inherent limit that anyone knows about on the sizes of the print jobs?  The difference between last week & this week was that the images were all edited to have deeper blacks & more dimension/separation -- that is, print image quality improved.

Thanks in advance...

Hard to say, but looking at the most obvious thing first - previews of files can show without the files themselves being recognized by Lightroom if their location on your hard drive by any chance now differs from where your Lightroom catalog thinks they are. This can happen is you changed file locations "behind Lightroom's back" rather than from within the Library Module of Lightroom. Did you do anything like that? If so, could be that the Print module couldn't access the data, triggering that error. Not saying this is necessarily what happened, but guessing from afar - a possibility.

Thanks, but the underlying raw files are all there.  Lightroom is quite happy with the print job.  It finishes without error.

The issue is that the print queue appears to start sending things to the printer before Lightroom has finished producing the print job.  Then, when Lr finally finishes, the job's aborted.

Making the job "smaller" appears to avoid the issue (and I could then have a second job that prints more "contacts" separately successfully).  I don't know if it's really a print job sizerelated issue or not.  That was just the workaround.

Fred,

I'm working with the same OS and same Epson drivers.  Without any issues. 

The only difference between our set ups is I'm using USB instead of WIFI.

Iíve found WiFi and the sc p800 unreliable and prone to incomplete print jobs. This, even with the printer only 6 ft from the router. USB, no problems.

WiFi issues possible, but worked fine with smaller job. And timing was very consistent. WiFi issues would tend to vary. But will be worth trying a USB or wired connection. Thanks!

That said, the error log content...

Since WiFi performance often is a mystery unless you have some tools I wouldn't discount WiFi as the source of your issues.  Bandwidth and buffering of data in your computer or P800 may be worth considering. 

You might consider getting "WiFi Scanner" from the Mac App Store to see what is really going on at a somewhat high level or some other tool. 

The app will detail all the WiFi signals it can detect along with Signal strength, Noise, Channel, Band, Mode, Security and Max Rate.  If you're a network engineer you might consider this pretty rudimentary but it may also be what you need for determining if your WiFi is sufficient.

I've been experiencing "filter failure" errors when printing to my Epson P800 hardwired to my LAN using Capture One Pro 12. The error occurs only when printing sizes greater than 8x10. I've tried the usual things, uninstalling and reinstalling drivers, etc, to no avail. My workstation is a first generation iMac Pro running Mojave. The problem started with Mojave.

Neither Capture One, Epson or Apple tech support have been able to help on this.

My workaround is to create a TIFF of my final image and then print using On1 Photo RAW 2019. I can also print from Apple Preview without any issues.

I just installed the Epson Print Layout to use as a plug in for Capture One Pro. I have not tried this yet, so we shall see if it solves the problem.

I just installed the latest version of Capture One Pro 12, version 12.0.3, and made a few prints from within the app. To my pleasant surprise, I printed a few 11x14 prints on 13x19 paper without any "filter fail" errors. Perhaps the latest update addressed the problem that I was having printing to my Epson P800 printer.

Keeping my fingers crossed for now.

A potential answer.  There was a thread/topic 7 years or so ago about maximum CUPS size.  It didn't appear that there was ever a true resolution.  That topic can be found at Maximum spool file size when using Mac/CUPS?.

(CUPS is the underlying print system in MacOS.  Formerly, Common Unix Printing System, now just CUPS.)

I looked at the various CUPS docs & configurations to see if there were any limits engaged by default -- there do not appear to be.  The default value is zero (0), meaning unlimited. (Well, sort of unlimited, I think.)

So I downloaded the source code for CUPS. Therein, I found that the limit on file size within CUPS is stored in a C-language integer.  Generally, these are 4 bytes long, with a maximum value of 2 Gig.  So, my educated guess is that the spool file was larger than was trackable, and that caused the print job first to begin attempting to run, then to abort, probably due to arithmetic overflow or inability to compare to actual size.

More research required (specifically what the spool file size actually is).  But this line of inquiry looks promising.

I print infrequently so every job is a 'fingers crossed' business. But I've found that even printing through USB there is at least one 'choke point' between LR/Mac (MBP with a lot of RAM) possibly due to CUPS (see above). But I don't know for sure. The problem is that Mac OS offers NO help in diagnosing printing problems. Zip! So I have no information on where the critical point of failure may be.

But I have found by experiment that printing to A2 sized prints on my SC-P800 is reliable ONLY when I limit the LR DPI of the print to at most 480 dpi (printing in 16-bit color). I set the printer dialog to print at "Superfine 1440 dpi" however, which is exactly 3x the LR DPI. This appears to give me very fine resolution on the paper and (most importantly) no aborts.

i suspect the problem is not hardware related on either side of the print pipe-line. I think it's a software issue. I'd love to find a specialised piece of Mac OS software that would examine/reveal/correct the problems. If you know of such an utility, please let everyone know.

Best, P

Problem solved.

As it turns out, the actual problem had nothing to do with the job size, per se. Instead, it had to do with the time it took to produce the job.

From the looks of things, Lr makes the connection to the printer at the time it starts to build the print job.  On my MacBook Air, producing that print job took over 5 minutes.  As it happens, 5 minutes (300 seconds) is the default timeout period. So, most of the way through the job, it timed the job out, cancelled it, and marked it aborted.

Solution:  Increase the timeout period to some number sufficiently large.  Specifically, in the terminal, run
    sudo cupsctl Timeout=5400
(sudo -- as the admin) (cupsctl -- program controlling the printing system) (Timeout -- the timeout parameter) (=5400 -- 90 minutes in seconds)


Diagnosis mechanism:  (I'm a software developer of nearly 40 years, so that helps here.)
  • Open the print queue -- from the Printer menu, bring up the error log -- see nothing of value
  • Turn on debug logging -- sudo cupsctl Loglevel=debug
  • Attempt to print.  Watch for errors...
  • Eventually, find message of the form Timeout after 300 seconds
  • Search web for that message.  Find similar hints, find someone who looks at Timeout CUPS config
  • sudo cupsctl Timeout=5400
  • ;) 90 minutes should be long enough.
  • Retry print job.  Success!  8)

Admittedly, a bit involved.  Having low-level system server development experience helps.

Well done! Have to remember that one: cupsctrl.

What would it have taken for the developers (of the printer driver?) to give you (us) a meaningful error message such as "Sorry, you ran out of time (300s) in the print job preparation" instead of "job aborted!"?

Lazy! Instead you had to dig through Log files!

Since you are a developer of longstanding you may remember Don Knuth's wonderful essay "The Errors of TeX" (ungated version here::https://yurichev.com/mirrors/knuth1989.pdf) in which he shows how to write a REAL error message, among many other useful ideas.  If only modern developers had the same humility and cared so much about their craft. (I'm prepared to believe they do but suffer disincentives).

Excellent detective work, and makes me wonder why such detective work should be necessary in the first place. I think it worthwhile bringing this matter to Epson's attention. While it seems to be an unusual problem, perhaps they could design something into the next version of the firmware or driver to make it easy for users to determine whether they have this issue and provide an accessible control for augmenting the timing.

W THE ACTUAL F....  Good job Fred, I'm not sure how more than 5 people in the userbase were supposed to figure this one out.  Poor little MBAir - the little laptop that could, if only given enough time.

I don't disagree, though (unfortunately, putting on my software dev's hat again), the trouble in tracking this down is actually with CUPS.  Lr took a long time (yeah, I should probably upgrade my machine) and then CUPS dropped the ball.  To a large extent, it never even got to Epson.

CUPS is open source -- which means its available, I can look at the source, but there's no there there (i.e. no one to blame).  Which means the responsibility to fix lies with Apple (as the consumer of CUPS here).

I have a ToDo to go find out how to file a bug...  Maybe I can file a CUPS issue.

Thanks all -- hopefully this is of help to someone else.  I'll add it to my Lightroom Special Needs class...

FYI:

Hopefully some good karma -- I have low expectations of any of these being addressed any time soon.  ::)

I'm confused.  Is the timeout period in Lightroom?  Apple MacOS?  Epson? Where is the fix needed?

Also... much RAM and disk space do you have in your MBP?
