Re: CUPS

      ...
Das ist ja auch nicht falsch. ...aber was macht der CUPS-Server zu dem

	Interpretation:

	Job meldet sich mit Nr. 72855 und wird gespoolt
	"DEBUG: lpd_command returning 0\nD"..., 1023) = 238
	Was passiert hier, antwortet das lp-Kommando des Clients nicht,
warum?
	Dann wird nach und nach gespoolt, beim normalen Job taucht nur 
	einmal eine % Angabe auf,
	hier gleich mehrmals, irgendwann ist er dann fertig
