Hi Kovalevich,
Thanks for the detailed context that really helps. What you’re running into is a situation where application managed print preferences are overriding the Windows or printer driver defaults. In Windows 11 many applications, including Adobe Acrobat and line‑of‑business software like Exact Macola are still allowed to manage and remember their own print settings for compatibility reasons. This means an application may reuse its last‑known copy count or apply an internal default which results in the behavior you’re seeing where the number of copies alternates between one and two even though the printer’s system‑level default is set to one.
To stabilize this the first thing to do is ensure the printer itself is truly locked to a single copy at the driver level. In Settings under Bluetooth and devices, go to Printers and scanners, select the HP Universal Printing PCL 6‑1 queue, open Printer Properties and then Printing Defaults on the Advanced tab. Make sure Copies is explicitly set to one there. In Printing Preferences or Device Settings, disable Mopier Mode if it is enabled, turn off any Job Storage or Private Job options unless you actively use them and uncheck “Enable advanced printing features” under the Advanced settings. These options can cause the driver to handle copy counts at the device level rather than honoring application requests consistently which often leads to duplicate prints.
If that does not fully resolve the issue clearing out cached printing data helps remove stale settings that Windows or applications may be reusing. Removing the printer completely from Printers and scanners, stopping the Print Spooler service, clearing the contents of the spooler directory, restarting the service and then reinstalling the printer forces Windows to rebuild the print configuration from scratch. When reinstalling it’s best to use the latest HP‑recommended Windows 11 driver for your exact printer model instead of a generic Universal PCL driver if one is available as vendor‑specific drivers are usually better at enforcing a consistent default copy count.
Adobe Acrobat often needs its own adjustment as well since it can store print dialog presets independently of Windows. Inside Acrobat or Reader go to Preferences and locate the section for Documents or Printing that controls print dialog presets. Configure it to always use default settings instead of reusing the last settings and enable the option to use the system print dialog if available. After that open the Print dialog once, set Copies to one and let Acrobat save that state. This prevents Acrobat’s “remember last settings” behavior from reintroducing two copies on subsequent print jobs.
Exact Macola and similar ERP or accounting applications frequently maintain per‑report or per‑user print defaults internally. Within Macola’s print or form setup screens look for Copy Count or Print Defaults options tied to each report or layout and set them to one copy or to inherit Windows defaults where possible. If Macola maintains per‑user printing profiles resetting or clearing those profiles can also prevent the application from injecting its own copy count regardless of the Windows or driver settings.
On systems that are managed or locked down Windows policy settings can further reduce variability. Disabling advanced printing features through Group Policy under User Configuration for Printers reinforces the driver‑level setting and limits how much control applications have over job rendering and copy handling. If a print server is involved keeping the “Render print jobs on client computers” behavior consistent often by disabling it can also produce more predictable results.
Finally it’s worth checking a few common quirks that frequently cause two copies to print. Some drivers link collate or duplex shortcuts to preset copy counts so reviewing or removing custom print shortcuts in Printing Preferences can help. Also make sure you don’t have multiple queues for the same device as different queues can have different defaults. After making these changes test printing from a simple app like Notepad first, then Edge, Office, Acrobat and Exact Macola. If all of them consistently default to one copy you can be confident the issue is resolved, if a specific app still shows two that app’s internal print settings are the place to focus next.
