In situations where the windows desktop is not loaded - like citrix, custom shells for industrial use, etc - printing is really slow.
It looks like the spooler sends the spooled jobs to the printer one by one; we did some tests on a label printer (we let our program print 50 labels) and saw the following:
Without the windows desktop:
The program prints a label to the spooler, the label is printed, and after that, the program sends the next label to the printer.
It took about 3 minutes to print the labels, and the program was also busy during this time.
Same machine, same program, but with the windows desktop loaded:
The program prints all labels to the spooler. Before the first label is fysically printed, all 50 labels are spooled. The thruput at the printer is more than twice as fast.
The program spooled the jobs in less than 10 seconds, and the printer took about 1.5 minutes to prit the labels.
I have seen this behaviour with a lot of installations.
Can anyone explain why printing is so slow when the desktop isn't loaded, and has anyone a work around how to speed up the printing process without loading the desktop?
Can anyone ex
