Hello,
I am trying to get the Next to print using the driver as described in the example, with the sample basic programs.

The printer is a HP LaserJet P1006 connected via USB through a Windows 10 PC running the WinPrintServer program (thank you)

F:\>WinPrintServer.exe
Print Server Started for 'HP LaserJet Direct'
waiting for connection
connection from 192.168.1.136
print job started

When I run the next program I can see the WinPrintServer connect as above, and I see the spool files in the 

C:\Windows\System32\spool\PRINTERS

Using Spectrum NEXT with v2.09 (though it was the same with 2.08) and the latest version of the driver.

Hi,

It looks like the driver is not closing the connection after the print job is complete so the WinPrintServer is waiting for more data. Are you calling "Close #3" or uninstalling the driver after printing? If so, comment that out and see if there is a difference.

Best Regards,

Chris

ah yup,  I see that now your right I had close #3 after the Lprint, things have improved with the Print Job completing 
However still no print unfortunately, though occasionally the printer does go through a start up as if its getting ready to print.. which is such a tease !

The one other issue with RAW printing from Windows is that there are two supported models either "RAW" or "XPS_PASS". Can you check your driver model and version and share that.

In the meantime, I will write a new Print server that uses GDI that would be guaranteed to work. Would you mind providing some testing support as I only have limited printers on hand and of course they all work, so if you would not mind that would be great.

Would be happy to help test  out, will let you know the driver version etc 

it would appear to be RAW as the default data type 

Hi,

If you get a chance, can you please test the new RawPrintServer.  To test it, I wrote this as a quick .NET App, hopefully you can run it, it is packaged as a self-contained app so you should not need any additional dependencies. If this works, I will add support for specifying alternate fonts, custom margins etc.
