Ich habe die Änderungen genau aus deinem Post kopiert.
Also:
connect_grace=1
connect_retry=100
connect_interval=100
max_connect_interval=200
send_try=0
send_failure_action=retry
(Jeweils noch mit einem Doppelpunkt davor)

Mit den oben genannten Einträgen (einzeln habe ich sie bisher nicht
getestet, sondern nur so gesamt) hat er im Sekundentakt, ohne dass sich
die Zeitspanne vergrößert hat, versucht, den Druck abzusetzen, bis ich
dann, nach einer Stunde, den Drucker eingeschaltet habe und den Ausdruck
erhalten habe.

Hier mal die Ausgabe nach meinem Versuch mit dem ausgeschalteten Drucker:

Das habe ich nicht getestet.
Ich habe bei mir zwei Drucker angeschlossen.
/dev/usb/lp0 ist ein Tintenstrahldrucker, der keinen richtigen Schalter
besitzt und daher immer eingeschaltet (Standby) ist.
/dev/usb/lp1 ist der Laserdrucker, der beim Start des Servers
ausgeschaltet ist und nur bei Bedarf kurzzeitig eingeschaltet wird.

Ich hoffe, du kannst mit meinen Informationen etwas anfangen.
Ansonsten musst du mir sagen, was ich noch ausprobieren soll.

Sascha
