PDF-XChange Lite V7 => CPU

Post by ChrisZ16 »

Windows 7 64-bit
Word 2010 32-bit

If I select PDF-XChange Lite V7 323.2 as printer in Word, CPU usage of Word jumps from 0% to 40%. Additionally splwow64.exe goes from 0% to 4% and Windows 7 sidebar.exe (I use the desktop watch) from 0% to 3%. Obvious sign is the cursor (mouse and keyboard) constantly flickering in Word from the CPU load. I cannot work like that. This was not the case with V6.

It does not make a difference, if I switch the PDF-XChange printer settings from Auto to GDI or XPS.

If I switch to another printer driver in Word, everything goes back to normal.

I have PDF-XChange Lite as standard printer in Windows and outside of Word I do not see this problem.

Hello ChrisZ16,

Does this happen only while you have Word "printing" to the Lite driver, or does the CPU load continue even after the print job has completed, and you try to continue working with Word?

Regards,
Stefan

Hello Stefan,

It is all the time like that, independent of printing. Right from the start of Word, until I select another printer.

At first sight, I do not have the problem with the 32-bit version of PDF-XChange Standard (build 323) nor -Lite Free (build 323.2).

As a work-around, you can think about activating the AutoUnload parameter that will automatically stop the printer after max. 30 seconds.
(via right mouse click on the pdf-xchange printer icon in the Windows System Tray = right side of the Task bar, and then click Settings)

Regards.

Thanks for your time, Willy, and Merry Christmas!

I do not have any printer icons in the Windows System Tray, so I assume you mean the pdfSaver icon? I don't have pdfSaver running, I always uncheck it on installation (also in earlier V6, was no problem). But the .exe is here, so I started it manually and tried your work-around, but it did not help. pdfSaver starts and auto-unloads after 30 secs (but I anyway don't have it running normally), the CPU load stays the same.

BTW: The list of installed printers in Windows shows "PDF-XChange Lite V6", but in the properties it says "Version 7.0 (Build 323.2)". I guess this is only a naming thing? I have the registered version of PDF-XChange Editor V7 323.2 and the PDF-XChange Lite, that comes with it.

Hi, Stefan!

This happens immediately after PDF-XChange Standard was chosen in Word's print dialog

Also a Merry Christmas to everyone.

Sorry, I totally misunderstood the problem. I thought it was the printing process that kept hanging.

The problem is rather with the interaction between Microsoft Word and the default printer. In this case, PDF-XChange Standard or Lite.

From the moment that you start Word, it interacts with the printer about fonts that can be used, page layout, ...

I do not know if you are using some uncommon default font in your documents, or a page format that is different from the printer's default ...

Do you have the problem with all your documents or just with some specific documents.

You might also post a sample document to see if the problem is reproducible at someone else's side.

Myself, I do not see any delay while typing in Word 2010 whilst PDF-XChange Standard printer (V7 323 - Nov. 30, 2017) is set as default printer.

Best regards.

Thank you for reply, Willy!
This happen even with empty document. I just change printer to PDF-XChange Standard.
So far this happens only with MS Office.

What you still can do to raise the performance of Word is:
1) turn off Auto-correct
2) turn off automatic Grammar and Spelling check
3) turn off (all) "Auto-format as you Type" options

Same here - it happens with every document, even with an empty one.

Regarding turning off Auto-correct, automatic Grammar and Spelling check, (all) "Auto-format as you Type" - most of these are turned off anyway. I also turned off the remaining ones. It did not change anything.

To point out again: The CPU-load does not happen with V6, which I use for years. It is a problem with V7.

Hi everyone!

Hope you all had a lovely Christmas!
I will now pass this to our devs and ask them to look at why this is happening!

Hello OVG,

I have some further news - apparently we had managed to reproduce this on a development machine, and my colleagues will now investigate why this is happening and try to resolve it asap!

Cheers,
Stefan

Re: PDF-XChange Lite V7 => CPU  SOLVED

Post by Roman - Tracker Supp »

Hi All,
The issue has been resolved (assuming all the reported cases are caused by the problem we managed to reproduce).
As a temporary workaround please delete the registry value "Default DevMode" under the key "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print\Printers\<printer name>" (e.g. "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print\Printers\PDF-XChange Standard").

To do this you can use Windows Registry Editor (regedit.exe) or a console command like this (run with elevated permissions (as Administrator)):

Code: Select all

reg delete "HKLM\SYSTEM\CurrentControlSet\Control\Print\Printers\PDF-XChange Standard" /v "Default DevMode" /f
UPDATE:
Print Spooler service restart is required after this change.
Use Windows Services snap-in or console command like this (run with elevated permissions (as Administrator)):

Code: Select all

net stop spooler && net start spooler

Hello Ovg,
Thank you for the feedback and you are right - I forgot to mention that Print spooler service needs to be restarted after that registry change.
I will update my previous post.
