I just open the sharpening, click ok and then it's applied?
That is interesting. First the ppi / dpi In this case they are interchangeable. A guide to ppi https://resources.printhandbook.com/page...inting.php but save that for later.
Question. Does the 110mm x 90 mm include the 3 mm margin ? Is the initial crop in a 113:93 ratio or is your 110:90 correct ?
If the Printer uses 150 ppi then you should use 150 ppi and set that in the Image -> Print Size resolution. That ends up with an image size of 667 x 549 pixels for a printing size of 113mm x 93mm. Not photo quality but probably applicable to type of printing material. A plain card or an absorbent art paper is never photo quality.
To sharpen or not to sharpen is all a matter of preference. Going by the above probably no.
This is a 113mm 93mm @ 150 ppi crop and scale. The scale shows at 34% , which is about a low as I would like to go. Open it up in Gimp, check the Image -> Print Size for 150 ppi
