Using Logical Printers The AXIS 540/640 has a powerful facility for altering the print data. to Customise your This means that your desired print format can be realised on any type
Printing of printer. The following actions may be invoked from the AXIS 540/640:
•The character set can be changed to suit the printer
•Strings can be added before and after the print data
•Strings within the print data can be substituted
•ASCII to PostScript conversion
•Hex Dump mode to assist with printing problems
If any of these actions are required a Logical Printer is used to change the print data before being sent to the printer port. There are eight logical printers that can be set up to filter the print data.
Edit the parameters in the AXIS 540/640 config file to configure a logical printer. Refer to Appendix A - The Test Button. The default logical printers settings are such that PR1 - PR4 cause no change to the flow of print data, while PR5 - PR8 add CR to LF control characters:

Logical Printer: A logical printer acts as a filter between the network and the physical printer. It appears to the user as a normal printer with additional characteristics. For example, a UNIX workstation may only send a line feed (LF) to a shared printer that requires both a carriage return (CR) and LF. The logical printer can solve this problem by adding a CR.
