Onyx PosterShop 25.0.2 + HP DesignJet Z9+ Pro 64" — "Invalid settings, no compatible print modes were found" on fast/1p print mode only

[LostInIllinois]

I'm an IT person, not a print or design person, so I'm hoping someone here can provide some help here. I've contacted Onyx for support, but they still haven't gotten back to me and I'm running into some serious deadlines. I've worked with Onyx PosterShop before when we had an HP DesignJet Z6810, but we've just upgraded to the Z9+ Pro and I'm hitting a brick wall.

Setup:

• Onyx PosterShop 25.0.2 (released February 13, 2026)
• HP DesignJet Z9+ Pro 64", firmware version LION_05_25_11.1
• Media: HP Universal Instant-dry Gloss Photo Paper
• Media types were downloaded from Onyx using the Download Manager along with the ICC profiles for each

The problem: I created two quicksets from scratch in Onyx for the Z9+ Pro, selecting all print modes strictly from Onyx's own dropdown menus — nothing typed in manually. One quickset uses "normal, 300dpi, 2p, 60ips, bidir" and prints successfully. The other uses "fast, 300dpi, 1p, 60ips, bidir" and fails every time with two error messages:

- In the Onyx RIP Queue console: 42: RESULT_ERROR_ELEMENT_NOT_FOUND

- In a Windows modal dialog box titled "Warning - HP DesignJet Z9 Pro 64": Invalid settings, no compatible print modes were found

Both quicksets were built independently from scratch, not by copying or duplicating each other, and both use "Default Printer ICC" as the output profile. To the best of my recollection they are otherwise configured identically, with the only difference being the print mode selection.

Important detail about when the errors occur: Neither error occurs during RIPping. The console shows the job RIPs successfully and reports "ready to print" — and only after that do both error messages appear. This seems to be a send-to-printer failure, not a RIP failure.

Onyx itself offers the fast/1p mode in its own dropdown menu as an available option for this printer — I didn't create or type this mode manually. Yet when Onyx tries to execute it, it fails with "no compatible print modes were found."

What I've already tried:

• Matching the printer's front panel Print Quality setting (Settings > Default Printing Configuration) to Fast
• Setting the printer's RGB source profile to None
• Setting the printer's CMYK source profile to US Web Coated (SWOP) v2
• Running the Download Manager to get the full Z9+ Pro profile pack from Onyx
• Contacted Onyx support multiple times including by phone without resolution — they suggested reinstalling from scratch, which I have already done twice without success

I freely admit I've possibly made things worse with the changes I've tried, but at this point I would accept printing a job even if the colors are completely horrible, because then I should be able to fix that.

What should I be looking at?

Im not super familiar with these but If it's anything like latex, you must make the printmode in the printer first.
Then you can simply import it to Onyx from the printer.

I've looked in every menu option on the printer itself, and I'm not seeing a way to create a new print mode. The print modes are defined in the media I downloaded from Onyx, but I'm not seeing a corresponding place in the Z9+ to match the print mode. Update: The only thing I can set is between normal, best, and fast; I'm not seeing an option to choose DPI or print pass settings, for example.

There's a lot more stuff about it in the user guide but it might simply not support 1pass at all.

Fast could very well be 2pass.

What's weird is I'm not seeing a 2 pass mode. It goes from 1 pass to 4 pass. But I tried to set up a 4 pass mode, and I'm getting the exact same error.
