#! /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

Forudsætninger: Dette script køres efter scriptet “Printer - Installer Princh Cloud Printer”.

Har i endnu ikke en Princh-aftale, men ønsker at teste oplevelsen med det, stiller Princh dette test printer-ID til rådighed, som du kan indtaste som inputparameter til dette script: 990000

Vi tager udgangspunkt i Princh’s egen installationsguide - hvis man vil kigge nærmere på den, kan den findes her: https://2803061.fs1.hubspotusercontent-na1.net/hubfs/2803061/Setup%20and%20installation%20guides,%20tech%20reqs/Princh%20for%20Linux%20Installation%20Guide.pdf

Dette script er blevet testet og virker på Ubuntu 22.04.

Parametre

1. Navn: Det navn printeren får i print-dialogen på BorgerPCen. Navnet mi ikke indeholde Æ, Ø, Å, mellemrum, skråstreg eller apostroffer.

2. ID: Dette ID identificerer printeren fra Princhs side, og det skulle de kunne oplyse til dig. Det er et 6-cifret tal.

3. Beskrivelse / Placering: Beskrivelsen printeren får i print-dialogen på BorgerPCen. Den må ikke indeholder æ ø å. Indeholder den mellemrum skal den skrives med citationstegn omkring. F. eks. "Printer ved info-skranken"

4. Sæt som standardprinter: Sæt hak hvis den skal være standardprinteren.
