We've just installed a new HP P3015x laserjet printer for printing our C5 envelopes. Unfortunately, it's not possible to enter the C5 size as a standard paper size in the printer. So we use "Any size" as the setting for the paper format.
This results in the printer printing the envelopes perfectly, but terribly slow, around 2 per minute. Is there any way to print this faster? We've tried messing with all kinds of settings but it didn't work for us.
Thanks in advance.
