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