SImilar issues here;
Brand new printer, arrived today.
Used the software provided with it.
While it offers the filename when I try to print it says 'unrecognised file type' and drops out to the main menu.
I used the USB drive provided, then I tried another one, then I gave it a full format and retried. Same result every time. 'Unrecognised filetype'
It's the only file on a freshly formatted USB drive, I have tried saving it directly, saving it to HD and copying it over, no benefit.
Evidence at this point is that the printer is incompatible with its own software. I'll try the beta version.
