Label Print Times Slow and/or delayed

We have had several customers report that when printing labels from the software, it can take up to 20 seconds for the labels to begin printing, and when they do there can be long pauses between individual labels being printed.
I.E. they need to print 10 labels, and after about 20 seconds 5 print out, then a pause of around 3-10 seconds 3 more print out, then another pause before the last two are printed.

Please let us know if you are also experiencing this so we can collect more data on what may be causing this.
