- Level One Printer Servers User Guide

TCP/IP
Logical Printer Configuration
Logical Printers can be used to create a “Virtual” printer. For example, to create a
Landscape printer, you could define a Logical Printer as follows:
Pre-string
Printer Control codes to switch the printer to Landscape mode
Post-string
Printer Control codes to reset the printer, restoring the default
settings.
Another logical printer could be used to print Unix-format text files for a DOS printer, by
converting Unix-style LF (Line Feeds) to DOS-style LF/CR (Line Feed, Carriage Return)
pairs.
The LevelOne Printer Server supports 8 Logical Printers. The names (L1..L8) cannot be
changed. Each Logical Printer has 4 settings as shown below.
Logical Printer Setup Data
Physical Port
LevelOne Printer Server parallel port (P1 to P3) to which
the printer is attached.
String Before Job
The printer control string (in hex) to be sent to the
printer before each print job.
String After Job
The printer control string (in hex) to be sent to the
printer after each print job.
Convert LF to
CR+LF
If ON, LF (line feed) characters are changed to CR+LF
(carriage return + line feed). If OFF, no conversion is
done.
The maximum size of printer control strings is 15 characters, and
they must be entered in HEX.
