Add and configure a print server for the Brother P-touch QL 500 label printer, so that it can be easily used via SSH. Do the following to make that work: - Configure the print server host. - Package printer-driver-ptouch to have a working driver for the label printer. - Configure CUPS. - Add a script "forcecommand-lpr-wrapper", which works together with the ForceCommand sshd_config option and wraps lpr to provide an easy interface to use the Brother QL 500 label printer via SSH. - Add a print user and configure SSH to have the "forcecommand-lpr-wrapper" script accessible without a password using the print user via SSH.
