Besides the obvious advantages of avoiding damage to your printers, the following become apparent.. 1.) You can print to both printers simultaneously. Many times I am printing a word dsocument on my laser, and a color graphics presentation on the HP deskjet. 2.) If you share any of your printers to other systems on a network, then you don't have to worry about remote users printing to the wrong printer. 3.) If you have an A/B switch, and forget to switch to the right printer, you will likely get garbage which could do strange things to the printer, or waste paper and ink/toner. 4.) Many printer drivers (particularly HP) want to communicate bi-directinally with the printer, using a switch will likely cause confusion for the driver. -- Russ Poffenberger Engineering Specialist Schlumberger Technologies ATE DOMAIN: [log in to unmask] 1601 Technology Drive San Jose, Ca. 95110 Voice: (408)437-5254 FAX: (408)437-5246 PCBUILD maintains hundreds of useful files for download visit our download web page at: http://nospin.com/pc/files.html
