Q: When I print, I get a stair-step effect.
A: The reason for this is your host (likely a UNIX system) uses LF as the end-of-line character and the printer is expecting CR/LF.
In brief, add the "Unix to DOS" transform to the setup for this queue. This assumes you are using the Raw Print action. We have found it's very typical for printers marketing to work with Windows to not handle line feeds well.
The Text Print action would correct this problem automatically.
