#! /usr/bin/env sh

# This script sets printer options in various different ways based on what seems to work.
# lpadmin makes changes in the PPD of the specified printer
# lpoptions creates a config file in /etc/cups/lpoptions. It's global for all printers.
# Sometimes it appears as if lpoptions settings take precedence over lpadmin (PPD) settings. GNOME Settings appears to set options via lpadmin (PPD).
# Papersize is globally configured for all printers via paperconfig - and it's also set via lpoptions AND lpadmin to hopefully cover all bases.
# Orientation modifies /etc/cups/printers.conf, which should be shared by all printers. When set via lpadmin or lpoptions it may not work, at least not according to GNOME Settings for a given printer.

Beskrivelse

Script, der sætter de printer-indstillinger (kaldet “Options” i Linux-printersystemet CUPS), der er forespurgt og fundet.

Kør scriptet “Vis printer-indstillinger” for at se, hvilke indstillingsmuligheder, den givne printer har. De konkrete muligheder og de navnene for værdierne kan nemlig variere fra printer til printer.

Hvis du ønsker at sætte indstillinger som orientering og duplex for en Princh-printer, skal dette i stedet gøres via Princh’s egen Princh Admin.
Vil kun virke, hvis der er en PPD-fil eller hvis printeren er sat op med IPP Everywhere.

Dette script er blevet testet og virker på Ubuntu 22.04.
