8 University of Pisa Computer Science Department dr. Stefano Bistarelli: System Administration Printing - Linux Cosa è una coda? Per stampare occorre solo lpr, solo lpd, o entrambi? Per stampare in una stampante remota cosa occorre? Chi lancia lpd? Nel vostro pc è attivo? In quale script è lanciato lpd? lprlpd Stampante locale Coda remota cf*, df*

9 University of Pisa Computer Science Department dr. Stefano Bistarelli: System Administration Installazione di una stampante locale Volontario/I?

10 University of Pisa Computer Science Department dr. Stefano Bistarelli: System Administration Stampante locale Utilizzo tool grafico Visualizzazione configurazione su file \etc\printcap

11 University of Pisa Computer Science Department dr. Stefano Bistarelli: System Administration \etc\printcap Nomistampante (separati da |) Sd = spool directory 1 per ogni stampante che si vuole usare Contiene lock e status della stampante Lf = error log Anche lo stesso per tutte le stampanti Af = accounting Lp = device di stampa Controlla sia con diritti rw se lo uso non solo per scrivere ma anche per leggere status

12 University of Pisa Computer Science Department dr. Stefano Bistarelli: System Administration Installazione stampante remota 17 volontari

13 University of Pisa Computer Science Department dr. Stefano Bistarelli: System Administration Stampante remota Tool grafico Esame del printcap

14 University of Pisa Computer Science Department dr. Stefano Bistarelli: System Administration /etc/printcap Rm = remote server Rp = remote printer Rs = restrict remote users to those with local accounts

Stefano Bistarelli: System Administration \etc\printcap AfstrNULLname of accounting file IfstrNULLname of text filter which does accounting Lfstr/dev/consoleerror logging file name Lostrlockname of lock file Lpstr/dev/lpdevice name to open for output pc num 200 price per foot or page in hundredths of cents pl num 66 page length (in lines)

16 University of Pisa Computer Science Department dr. Stefano Bistarelli: System Administration \etc\printcap pw num 132 page width (in characters) px num 0 page width in pixels (horizontal) py num 0 page length in pixels (vertical) rg str NULL restricted group. Only members of group allowed access rm str NULL machine name for remote printer rp str ``lp'' remote printer name argument rs bool false restrict remote users to those with local accounts

17 University of Pisa Computer Science Department dr. Stefano Bistarelli: System Administration \etc\printcap rw bool false open the printer device for reading and writing sb bool false short banner (one line only) sc bool false suppress multiple copies sd str /var/spool/lpd spool directory st str status status file name tr str NULL trailer string to print when queue empties vf str NULL raster image filter
