Irregularities with Print Studio Pro


As best I can tell (per this prior post) Print Studio Pro (PSP) is necessary to obtain the benefits of the XPS driver for my Pixma Pro 100. Therefore, I'm wanting to use it even though it seems to be a bit of a hassle. In my case it would need to be invoked by the Canon supplied software for developing images call Digital Photo Professional (DPP).  Correct?

One issue I haven't been able to resolve is how to select multiple image files for printing. I've deduced that this must be possible since PSP seems to support page formats that are intended to print multiple pictures on the same page. So far I've only figured out how to select one picture at a time, in DPP, before invoking PSP and PSP, by itself, seems to have NO ability to select the image files to be printed.

In my case, I'm NOT presently wanting to print multiple pictures on a page but would definitely like to select a set of picture for printing at one time on different pages so that I don't have to keep closing and reopening PSP for every page, which is what I'm finding is necessary now.



PSP is a plug-in, so there is no way to invoke PSP by itself.

All you need to do is select the desired multiple images in the DPP file module and then select Plugin Printing.

PSP will open and you will see all your images at the bottom of the display. Select Print and the images will print one at a time.

From the Pro-100 On-Screen Manual:

Yes, that is the material I found which convinced me that multiple files could be processed by PSP.  Since it can NOT select them, I assumed it must be possible in DPP.  However, I haven't figured out how to do it.  My own research came across this topic in another forum.  It very well describes my experience but I'm afraid it does NOT provide a solution.

I've now noticed something in DPP for the first time (i.e., I have been using it for about 5 years now) that is called a "Collection".  I don't know the purpose of a "Collection" but I have figured out how to create one.  I think.  However, when I select a "Collection" prior to invoking PSP there is still only one picture that shows up in PSP.

That post is 9 years old; I'm not sure if it was even correct then.

1. In DPP CTRL-Click on each of the images you want to print:


Then, in DPP, select PlugIn Print,PSP opens

Here the same files are shown in PSP.

Select Print in PSP:



PSP starts processing the files.

Here is the printer driver dialogue showing three files to be printed.

The error message came up because I wasn't going to expend ink and paper.

Collections are explained in the DPP manual:

CTL-Click is a standard mechanism on all the computers I've used.  That is how I expected it to work.  It works fine everywhere on my computers but NOT in DPP.  I have tried on multiple computers using different versions of Windows but the behavior is the same.  That is the similarity to the nine year old problem that I referenced.

Possibly there is some kind of setting that affects this behavior which might explain why it works but NOT all of the time but knowing about that would be above my pay grade.  Although it is hard for me to imagine how I might have messed that up in the same way on multiple computers without knowing anything about it.

I just showed you that it works for me. There is either an execution issue or a computer issue affecting your system that I cannot resolve from a distance.

Perhaps you can get someone to sit alongside you to follow your steps or have a computer store checkout your system.

I have NOT been able to figure out what I was doing or was otherwise wrong.  However, without changing anything, other than giving up and coming back on another day, it now works as advertised on all of the computers on which I had been unable to make it work properly.

Looks like maybe I should have done that before before posting.  My apologies for troubling you in this instance.

I do have an idea for a possible cause but think it quite unlikely.  Each of the computers on which I tested the DPP4 results are run via a KVM switch.  In that, same keyboard and mouse used everywhere.  Therefore, an issue with keyboard/mouse would have same affect everywhere.  What this doesn't explain is why it wasn't noticed anytime but when using DPP4 as well as what made the problem go away.

Anyway looks good now.  Thanks for helping.
