There is a configuration file buried out of sight at C:\Users\xitron\AppData\Roaming\Xitron\HPPW
It might be useful to change some global settings there in some cases.
Here is what the file looks like when opened in a text editor:
[General]
FileOutputNumbered=0
FileOutputNamed=0
FileOutput=0
poolsizemb = 32
restcalls = 1
ipaddress = 192.168.1.1
The first 3 entries (FileOutput...) are for outputting a file instead of a print job and are discussed here.
Poolsizemb is our buffer or page pool and it's use is discussed here.
Restcalls are now handled inside the DFE. This should either either be at 1 or the entire line should be deleted. This is discussed here.
ipaddress is for setting the network address of the printer and is discussed here and here.
