Photoshop CC 2019: Print settings dialog box slow with Canon PRO-4000 printer

The Photoshop "Print Settings" dialog box is slow to open and slow to return to Photoshop when I'm printing to a Canon ImagePROGRAF PRO-4000 printer. It takes 3-5 seconds to open when I click CTRL-P and then, when I exit from the printer's dialog box, Photoshop freezes for 5-10 seconds before it returns control to me. During these delays, Task Manager shows "Spooler SubSystem App" jumping to the top processor-utilization spot and staying there. It's as though "Spooler SubSystem App" is taking a long time to do something, and Photoshop has to wait for it to do its thing before it continues working. This delay is only in Photoshop; there is no other significant delay in any other program or any other Creative Cloud app: Illustrator, InDesign, Lightroom Classic, Microsoft Word, GIMP, and all other apps work OK--except Photoshop.

Machine: Latest Windows 10 build, 4-core Intel Core i7 processor that's 4 years old, 16 GB RAM, Nvidia GTX 1080 card. Just upgraded to all CC 2019 apps. Photoshop is the latest build as of 11/4/2018. Printer is a brand-new Canon ImagePROGRAF PRO-4000 with the latest drivers.

Called Adobe support. They said they'd escalate after a screen sharing session and never called back. I called back 3 days later. I spent 2 hours and 15 minutes on the phone during a long screen sharing session. Problem not solved. Supervisor called back. Another long screen sharing session. Problem not solved. Installed the previous (2018) version of Photoshop. Problem not solved. We logged in under the administrator account. Problem not solved. We tried disabling the GPU, resetting preferences, uninstalling and reinstalling the printer driver. Problem not solved. In the end, the support person said that it's a problem with the Canon print driver. However, the Canon print driver is fast on all other apps except Photoshop. The s-l-o-w appearance and dismissing of the Canon print driver is only in Photoshop, and only with that printer.

Other than this delay, everything works flawlessly in Creative Cloud. Prints look gorgeous. I have not gotten any errors of any kind in any of the CC apps.

I ended up refreshing Windows and installing Creative Cloud on an SSD that I just bought. The computer previously had an SSD for the operating system and a magnetic disk for the installation of Creative Cloud. But now, everything is on an SSD. The problem is not as bad, but it still exists; it got better by about 20-30%.

I used Windows Process Monitor to see what was going on with Spooler SubSystem App and spoolsv.exe. During the time that Photoshop is delayed in opening the printer settings dialog box, spoolsv.exe is making hundreds of thousands of requests to the registry to look up printer-related information. Maybe that's a clue?

I hope that Adobe and Canon get together to fix this problem, as the delay is costing me money: I don't make money unless I ship out prints, and this is causing a significant delay in my workflow.
