212 Appendix
n For best printing results
•
Avoid printing in high humidity i.e., above 70% RH.
 High humidity may cause the envelope to curl and pick up excess toner.
 High humidity may also cause the envelope to seal.
•Avoid printing below 10°C (50°F) with less than 30% RH. 
Low temperature with low humidity may cause light printing.
•Print only one envelope at a time.
Envelope storage is very important. Store them away from moisture and 
humid air, where they can lay flat and their edges won’t be bent...

213 Appendix
The bidirectional parallel interface is based on the IEEE P1284-C standard.
If your computer has a bidirectional parallel port, the printer driver and 
printer can take advantage of faster data transfer.
