Backend hangs when more than one file is send for printing

[Mohit Kumar]

Hi All,

I have written a backend which converts any file to pdf file format. However I am facing a problem.

When I try to print a file when some other printing to the same backend is happening, the virtual printer seems to get hung.

Why is it that the jobs are not getting queued, and if they do, then what should I do to enable this?

Thanks,
Mohit
