Printer Acquisition Strategies CPIS 210 John Beckett
Why Print? • Documentary evidence • For yourself • For customer • Working paper • More convenient than something electronic
Why Not Print? • Costs money • Reveals information • One more piece of technology that can malfunction
Types of Needs • Kiosk • Gas pump • High-volume transaction • Cash register • Low-volume transaction • Registration book list • Batch • Bills for a mailing
Printing Technologies • Impact • Can make mechanical copies • Thermal • Simplest, most reliable for transactions • Ink-jet • Low-volume transactions • Laser • High-volume
Printer Communication • Direct connection to PC • May be shared on network • Direct connection to the network • Perhaps with a spooler/manager/controller • Could be WiFi • BlueTooth • FireWire • Not used much (yet)
Spooling Control • Can the person who made the mistake, cancel the job? • Where’s the data? • In the PC • In a spooler/buffer/controller somewhere • In the printer’s buffer memory
Controlling Cost • As with any technology: Reduce variation in sources and models • Reduces spare parts inventory • Reduces supplies inventory • Move to preview/print cycle • A printout more than a few pages shouldn’t happen until inspected in the spooler
Who Pays? • If the person making the “print” decision isn’t the same person making the “spend money” decision, you have a mis-match • If printouts are consistently ignored, make printing optional • Consider electronic distribution
