We support the Goodcom GT-90 for wireless printing with Accept/Reject functionality, and would advise ordering directly from the manufacturer which takes between 5-10 days and ensures the best price for your printer.
When inquiring about your order please ask for the GC Any Order app to be pre-installed.
If you would prefer to speak to Goodcom directly rather than use the Alibaba link then I’ve put the details of their team below who are very helpful and will get you up and running no doubt:
Email: info@igoodcom.com
WhatsApp: WA Business: +86 157 1060 6383
Once you receive the printer, contact us via our Live Chat and we'll get the printer configured with your app remotely so you don't need to do any installation or setup other than connecting the printer to your Wi-Fi
Any questions let us know
