As it turns out, the compression functionality was not implemented in the printers I am using--the manufacturer is working on a firmware version that handles compressed objects (fonts or images). I attempted to do this with base64, appending the calculated the CRC value as per the manual, but wasn't able to get that to work. For anyone wanting to do Base64, I found in an older manual that you need to manually calculate CRC codes for each packet you send so I chose to go with the easier Hexadecimal route.
