The IllegalOperatorSequence error you are receiving is coming from your printer and not from Musicroom
or the Scorch file you are attempting to print. You may wish to check if you have the latest available driver
for your printer.
You should be able to download the latest driver from the printer manufacturer's web site:
After downloading the driver, follow the instructions on the manufacturer’s website to install it.
Please contact
help@musicroom.com or call

assistance or if you need us to reset the system to allow you to try printing again.
