Hi Chris. When I run nextprintserver.exe, either by double clicking on it in Windows 11 or running it from a MSDOS window the program runs showing my attached printer in the box and there are also the pdf printing options slectable as normal in Windows. It also shows the Consolas font  and I can select others. However, I  have " Waiting for connection message" at the bottom of the running screen. I have checked the Next is connected to my router and the internet using NXTEL sucessfully.  I do not have your wi-fi printer driver running assuming that this is for direct communication to my printer and not required to use the nextprintserver software. Is that correct? If so, what part of the process am I missing to make nextprintserver connect to my printer. (Other info - My printer works with all my windows software. I am using an HP Envy 5546 printer, which does not work with your direct to printer wi-fi driver - it connects, but although the printer screen says "printing" it does not print anything, so I was hoping I would have success with nextprintserver. Thank you for your thoughts. Paul
