The 3 partitions are GPT and are of type

FreeBSD-Boot
FreeBSD-ZFS
FreeBSD-SWAP

I do not use GRUB, but you need to make a chainloader to the FreeBSD-Boot partition

If the GhostBSD drive has 3 partitions, it must be EFI partition FreeBSD-ZFS SWAP You need to launch /EFI/BOOT/BOOTX64.EFI user@host ~% gpart show => 40 3907029088 ada0 GPT (1.8T) 40 532480 1 efi (260M) 532520 3897387008 2 freebsd-zfs (1.8T) 3897919528 9099264 3 freebsd-swap (4.3G) 3907018792 10336 ...

I am not sure it's going to work since the environment variable PRINTER is not defined

To rename, you need to be root and run the next commands

It should be /usr/local/bin/lpr, this mean that XSane was using /usr/bin/lpr from LPD/LPR instead /usr/local/bin/lpr from CUPS

Renaming /usr/bin/lpr to /usr/bin/lpr.bsd should make XSane work

If you enable LPD/LPR, you need to disable CUPS, also need to make sure that when using lpr it is the /usr/bin/lpr GhostBSD use OpenRC, I recently solve my problem about SSH not running when the PC boot Para que el servicio de SSH inicie al arrancar GhostBSD, ejecutamos el siguiente comando como roo...

Did you logged out and in after modifying ~/.xsession?

With GhostBSD reinstalled, just configure your printer and set as default destination (in CUPS) If the option "Copy" of XSane doesn't work out of the box, then create the environment variable PRINTER, edit your ~/.xsession and add the next line export PRINTER=HP_LaserJet_200_color_M251nw F...

As I said, you are using CUPS, because is what GhostBSD configure by default

If you are using GhostBSD with it's standard config, then GhostBSD it's using CUPS, you should not enable LPD/LPR. Be careful, because a collision with lpr LPD/LPR ==> /usr/bin/lpr CUPS ==> /usr/local/bin/lpr Try setting the environment variable PRINTER; to list the printers available in CUPS, use l...

That means Xsane invokes lpr without specifying a destination printer (-P PrinterName), expecting lpr to use the user's configuration lpr selects the destination printer in the following order: If the -P PrinterName option was specified If PRINTER environment variable exist, it's value is used as th...
