lpn ist der erweiterte lp-Treiber fuer wega 3.2
|
||||
Mit mknod <lp> c 9 <min>
|
||||
sind die gewuenschten Eigenschaften und lp-namen zu installieren.
|
||||
Dabei sind Kombinationen moeglich:
|
||||
Fuer <min> gilt
|
||||
0x00 normal lp Parameter (66 Z, 128 Sp, 0)
|
||||
0x10 kein Seitenvorschub (0x0c) beim close
|
||||
0x20 keine Umschaltung auf raw-Mode bei ESC
|
||||
0x40 permanenter raw-Mode
|
||||
0x80 lp2 Parameter (90 Z, 160 Sp, 0)
|
||||
+3 (bei tty3 als Druckerkanal)
|
||||
Das Objekt lpn.o ist nach /usr/sys/dev/lp.o zu kopieren (moven) und mit
|
||||
ar rv LIB2 lp.o das alte lp.o zu ersetzen.
|
||||
Die beiden lp-Parameterfelder koennen mit setlp [-d /dev/lpx] angezeigt
|
||||
und veraendert werden.
|
||||
Zum Test fuer lx kann der Druckauftrag io3sys* dienen.
