Under workstations we also define the default printer with printer name and the Linux command to be executed.


Printer Command
MyPrinter lpr -P myPrinter




Using the -o option of the lpr command you can pass various options to the printer.

If you have a printer which is configured to normally print double-sided then you want to use this command:

Printer Command
MyPrinter lpr -P myPrinter -o sides=one-sided




The program will save this option but when reading it ends up like lpr -P myPrinter -o sides

The reason is that the default printer is saved as MyPrinter=lpr -P myPrinter -o sides=one-sided and after reading this line the program splits the string at the '=' sign into printer name (left side) and printer command (right side). As we have now two equal signs in the string '=one-sided' get's dropped.


Define a basic shell script containing the printer command.


# printer wrapper file for ledger
`lpr -P myPrinter -o sides=one-sided $1`
exit $?

Save the file as myprinter.sh, make sure that it is executable (chmod ugoa+x myprinter.sh) and define the filename as printer command in the system.


In a number of situations you may not be able to complete a transaction. Once you press Enter to submit data the file download dialog shows and you can only accept the download or cancel it.

This misbehaviour is normally due to incorrect data entry e.g. an invalid date was entered. Please download the file; then open it using either Notepad or any other editor. The file contains the exact error message e.g. "invalid date" . Then repeat the transaction and enter the data correctly.
