Lightroom: Really slow issues with print module in 3.4.1

Hi, I have a problem with the print module that I have not seen on any of the forums. In general Lightroom 3.4.1 runs well but it takes around 11 seconds to open the print module and if I select the page setup button it takes about 33 seconds to respond. I am using an Epson R2400 printer and have reinstalled the latest printer drivers. My system is running windows 7 64 bit with 6 mb RAM. Any ideas would be welcome.

Regards, Ron.

I think I noticed at one point that the Print module invokes certain commands that interface with the printer driver on the main thread in a way that blocks until completion. Usually this isn't a huge deal (not a great idea, but usually not awful), but in some cases it can mean slow module load times.

Do you by any chance have other printers that are configured but no longer accessible in addition to your R2400? Also, can you think of anything that was changed just prior to the slower switching times?

Thanks for your reply. I have an HP photosmart all in one printer that I use for general text printing that is in regular use and has been on the system for over a year - so I don't think that this is likely to interfere. I can't think of anything obvious that has happened on my system recently that may have caused this problem. I have however tried printing in Photoshop CS5 and found the same problem - so I guess that the cause is either common to both Adobe programs or there is some interference elsewhere.

I have the same problem as Ron but it just started for me a couple of months ago and has gotten progressively worse. I also have an Epson R2400 with a second everyday all in one Epson RX595 (set up same for over a year). The issue is only for the print module and exists in both Lightroom and Photoshop CS5. I noticed it with the update to LR 3.6 but around the same time I also upgraded two plug ins: Nik Color Efex Pro 4 and OnOne Perfect Photo Suite 6.

I've uninstalled and reinstalled both Lightroom and Nik CEP4 to no avail. Since I see no easy solutions here I will try the same with OnOne PPS and see if that might help. I am planning to increase ram from 4 to 6 but that may not help if Ron has 6 and still has the problem.

Yeah, I doubt this is an issue of memory usage. The delays are probably due to communication timeouts or something like that.

It'd be more likely that you'd get relief by either removing and re-adding the printers via control panel (and removing any old ones that are no longer reachable, perhaps) and/or re-installing the printer drivers.

We've seen a few long hangs in Print that vanished after re-installing the drivers. I tend to dislike making bugs go away like that internally instead of fixing the underlying problem, but it may be helpful in your case to try it.

Thanks Dan, Unfortunately this suggestion didn't work for me. Lightroom's print module is still is slow and unresponsive for long periods of time for each operation.

Rats, Print isn't an area that I know very well, so I don't have a lot of other ideas for how to fix this. I'll ask around and see if there's any other thoughts or whether 3.5 or 3.6 has any fixes relevant to Print issues.

Hi Pam,

I did find a solution to this problem in Adobe forums and am sorry that I did not post it.

In the folder C:\ProgramData\Epson\Printer there is a file called EPAUDF01.AUD. This file is usually VERY small - under 10kB, if this is large e.g.over 35MB it is not supposed to be. Try renaming the file and see if it corrects the problem.

Best of luck,

Ron.

Ron, thanks for your suggestion. I couldn't find the file you mentioned on my computer even when I used the search function. I'll have to go to the forums and search further for a solution to this annoying issue.

I appreciate everyone's suggestions!

This problem should not be listed as solved unless the full solution is recorded here!

You may need to turn on hidden folders on Windows to have access to that directory. What OS are you on?

Ron Brown - this solution worked for me on Windows 10 - I renamed the file and it instantly resolved my issues with Lightroom's Print Module being really slow.
