Other Printing Methods
Your LevelOne Printer Server supports 2 other printing methods:
• DSI (Direct Socket Interface)
• PSfilter (Proprietary print method)
Printing Using DSI
Logical printers must be configured on the LevelOne Printer Server as explained in Chapter
7 - TCP/IP (DSI supports only 3 Logical Printers).
Socket numbers are defined as follows:
Logical Printer No. Socket No.
1 4010
2 4020
3 4030
Printing Using PSfilter
PSfilter is a proprietary print method provided with the LevelOne Printer Server as “C”
source code. It provides many print options. To use PSfilter, a C compiler and Socket
Library must exist on the host so that psfilter.c can be compiled to an executable file.
The PSfilter program is shipped in source code as psfilter.c. Detailed instructions for
installing, configuring, and using PSfilter are provided in the following files. These files,
along with PSfilter.c, are stored on the CD-ROM in the following directories:
PS\driver\lpti\lpsource (text format)
PS\driver\lpti\tar (tar format)
