Answer: The EP emulation key allows Horizon to receive images from Pegasys using the
Codonics print driver provided on the Pegasys. This key is required for non-DICOM printer
installations. Most Pegasys printer installations use this driver and therefore require this key.
If you are replacing an NP series or EP series printer with a Horizon SF, you will very likely need
this key.

Question: The Horizon is prompting for 8x10 CV Paper. Where can I get this?
Answer: This is not a valid media combination. Check the Codonics configuration screen (either
through DICOM or the driver, depending on your installation.) Make sure that both the media size
and the media type are set up correctly.
Additionally, through DICOM make sure the AE title is a-cvp or a4-cvp, as appropriate.
