I am not at all an expert Linux user, but I do network and applications support for an office technology company.
One of our clients is a pharmacy which prints prescription labels through software called
RX30. This software sits on a Linux server, and after a recent firmware update on the Konica Minolta bizhub printer which we service for them, the machine began counting the black and white RX labels as color.
Unfortunately, we are not able to downgrade the firmware. I spoke with the support team at RX30, and they told me that they print via raw data dump over port 9100, and do not even use a driver.
My question is this: is there a place in the Linux OS where I can set a "default" for this hardware without installing a driver?
