Using Logical Ports
Logical ports can be used to create a "virtual" printer. For example, to create a landscape printer, you
could define a logical printer as:
• 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 example of the use of logical printers is to print UNIX-format text files properly, by
converting UNIX-style LF (Line Feeds) to DOS-style LF/CR (Line Feed, Carriage Return) pairs. Each
Model PS110 and PS113 Print Server, with two and three parallel ports respectively, supports eight
logical printers.
Configuring Logical Printers on the Print Server
To define pre-string, post-string, and the physical output port of a logical printer:
1. Execute the PSCONFIG program.
2. Select the PS110/PS113 print server, and then select Change Configuration.
3. Select Logical Printer Configuration, and then set the items listed in table “Logical Printer
Configuration Entries” in each of the appropriate entry fields.
Logical Printer Configuration Entries
Entry Field Definition
Physical Port
Select the physical port for this logical printer (P1 to P2 for parallel ports). Logical printers are numbered L1
to L8 for the Model PS110 and Model PS113 print server.
String Before
Job
The printer control string (in hexadecimal notation) to be sent to the printer before each print job. The
maximum number of ASCII characters in the control string is 15. The examples are:
ASCII = [Esc]&10O
Hexadecimal = 1B266C304F
ASCII = [Esc]&110
Hexadecimal = 1B266C314F
String After
Job
The printer control string (in hexadecimal notation) to be sent to the printer after each print job. The
maximum number of ASCII characters in the control string is 15.
Convert LF to
CR+LF
If On is indicated in the entry field, LF (line feed) characters are changed to CR+LF (carriage return + line
feed). If Off, no conversion is done.
Configuring NetWare File Server to Connect to Logical Printers
The NetWare PCONSOLE must be used to create connections to logical ports and assign print queues
to the ports. When creating logical printers, be sure to select printer numbers greater than 7 from the
Configured Printer listing. When operating in a NetWare environment, all printer numbers greater than
7 are logical printers. Remember that selecting printer 8 corresponds to logical printer L1, selecting
printer 9 corresponds to logical printer L2, and so on up to printer 15, which corresponds to logical
printer L8.
Refer to table “RPRINTER Mode Printer Name Mapping” for printer name mapping.
