Windows NT supports two types of print monitors: port monitors and language monitors. This chapter describes both monitor types, and provides design and implementation guidelines.
The Windows NT DDK supplies sample code for each type of monitor:
| Directory Name | Print Monitor Type and Comments |
| localmon | Port monitor. The resultant executable, localmon.exe, is the default port monitor shipped with Windows NT. |
| pjlmon | Language monitor for bidirectional printers that understand PJL. |
