Hi Chris, not had time to try Windows Printer Server yet, but can confirm on trying wfiprn.drv, the LED screen on my HP Envy 5547 displays "printing" so it appears to be connecting by nothing happens. I wrote a simple BASIC loop that simply keeps repeating the LPRINT "HELLO" command to see what happens and the Printer LED just constantly displays "printing" until I stop the program. I'm not a technical person, but it seems to me that the driver is connecting to the Printer, but for some reason the actual printing does not happen. The printer's status report says "Port 9100 enabled" It also says "WiFi Direct Off" . I have an SD card with a recent beta Next distro which I tried, just to see. On this the printer displays the printing message continuously with just a single LPRINT statement. I also tried your server software without a printer cable attached and got the message "HP Smart" ..."connecting" but it did not connect. I also changed my default printer to the actual printer name HP Envy ... and got the same result.
