Printing under UNIX

Under our AIX machines several remote printer queues are set up. You print for example with:

lpr -Ppsaa   <file>   # DEC lps20            in the RZ printer-room, PS and text
lpr -Ppshpad <file>   # HP Laserjet          in the RZ printer-room, PS and text
lpr -Ppsteka <file>   # Tektronix Phaser III in the RZ printer-room, PS Colour Paper  
lpr -Ppstekb <file>   # Tektronix Phaser II  in our office 4.183, PS Colour Transparencies
lpr -Pln03r_d <file>  # DEC LN03             in the Messhuette, PS and text
lpr -Pln03r_c <file>  # DEC LN03             KP1, PS and text
