I am using Adobe InDesign 21.6 on macOS Tahoe 26.7 with a Canon imagePRESS C650/C750 using Canon PS Printer Driver & Utilities 4.17.25.

The Canon printer driver itself works correctly. When printing from Apple Preview, all printer-specific settings are correctly remembered under “Last Used Settings”, including paper source, simplex/duplex, resolution, brightness and toner density adjustments.

The problem occurs only when the macOS printer dialog is opened from Adobe InDesign.

Environment

Adobe InDesign 21.6
macOS Tahoe 26.7
Intel iMac 27" 2020
Canon imagePRESS C650
Canon iPR C750 PS driver
Canon PS Printer Driver & Utilities 4.17.25
Printer connected via TCP/IP / LPD

Steps to reproduce

Open a new blank document in InDesign.
Choose File > Print.
Select the Canon printer.
Click “Printer…” to open the macOS / Canon printer dialog.
Select “Last Used Settings”.
Change several printer-specific settings, for example:
Paper source
Simplex / Duplex
600 / 1200 dpi
Brightness On/Off and brightness level
Toner Density Adjustment On/Off
Cyan / Magenta / Yellow / Black toner density sliders
Print the document.
Open File > Print > Printer… again.

Actual result

The Canon-specific settings are not restored correctly. The printer dialog returns to different/default settings instead of the values used for the previous print job.

This happens even with a newly created InDesign document.

Expected result

The macOS printer dialog should restore the exact settings from the previous print job when “Last Used Settings” is selected, just as it does when printing from Apple Preview.

Important diagnostic information

The issue does not appear to be caused by the Canon driver or by macOS itself:

The same Canon printer and Canon PS driver correctly remember all settings when printing from Apple Preview.
Another Canon printer on the same Mac correctly remembers duplex settings.
A manually saved macOS “Print Job Preset” correctly restores all Canon-specific options.
InDesign preferences were reset completely; the problem still returned.
The issue also occurs in a brand-new InDesign document.
Exporting an existing document to IDML and reopening it does not resolve the issue.

Most importantly, macOS correctly saves the Canon printer settings in:

~/Library/Preferences/com.apple.print.custompresets.forprinter.<printer>.plist

For example, the following values remain correctly stored before and after opening the printer dialog from InDesign:

InputSlot
CNDuplex
Resolution
CNUsePSBrightness
CNPSBrightness
CNTonerDensityAdjustment
CNTonerDensity
CNCTonerDensity
CNMTonerDensity
CNYTonerDensity

Opening the printer dialog from InDesign does not modify these stored values. However, the Canon/macOS print dialog opened from InDesign does not restore them correctly.

This suggests that the issue is in the interaction between InDesign’s print system and the macOS NSPrintInfo / printer driver interface, rather than in the Canon driver itself.

Additional observation

Temporarily switching to another printer inside InDesign and then switching back to the Canon printer can sometimes make the settings work again, but the problem returns later.

This makes the issue especially problematic in a production print environment, because printer settings such as paper tray, toner density and duplex mode change frequently between jobs and must reliably retain the previous values.

Requested investigation

Please investigate whether InDesign 21.6 correctly passes/restores the macOS NSPrintInfo / last-used printer settings when opening the native macOS printer dialog.
