Job not found in spooler when printint to a network printer (IPP)

Hi,

I am trying to get the job instance from a printer by
calling enumJobs in my printer driver plugin. In my
testing environment, if the printer is installed as a
local printer, job instance can be retrieved from
enumJobs through the printer handle. However, if the
printer is installed as a network IPP printer, printer
information returned from GetPrinter shows no job
(PRINTER_INFO_2.cJobs is 0) in the queue.

I think if a printer is installed as an IPP printer, the
job is sent directly to the printer without passing
through spooler. But I am not sure. If not, is there any
way to get the job information of the printing job? Could
anyone here clear up my mind?

Thanks,

Roy

It really depends on where in your plug-in you are calling EnumJobs and
also if this is a rendering plug-in or a UI plug-in. In most cases,
server-side rendering is what takes place in the case of network printers.
So you need to be in the right machine context in order to get the job
data. Maybe you can try calling it from the app level and see if that
works. Refer to the below KB article for more info on this.
