If you and your colleagues need to print spreadsheets on legal-size paper, produce marketing material on premium glossy media, or occasionally print a sheet of labels or a company check, you'll want a printer with multiple drawers or trays. Increased capacity is also a must if your office prints a great deal. Waiting for paper refills or constantly reconfiguring the drawer for different-sized media is a drag. Many printers come with a simple one-sheet override tray for printing one-off envelopes, forms, or labels. Some medium- and high-volume models come with (or can be expanded to use) multiple paper input sources, such as two drawers in the front of the chassis and a tray that pulls out from the back. Higher-end machines support paper-input expansion through add-on drawers and bins. Input capacity is related to a printer's volume, which manufacturers usually gauge on a monthly basis. The two most common measurements are the duty cycle (the peak number of pages the printer is rated for churning out each month) and the maximum suggested print volume (also expressed in number of pages per month). Typically, these volume measurements are miles apart. When a machine's monthly duty cycle is, say, 50,000 pages, the suggested monthly volume is usually 10 percent of that or less. When buying a medium- or high-volume printer, it's best to let the suggested print volume be your guide. While a printer can run pegged out at its maximum duty cycle month in and month out, it will require less attention and last a lot longer if you hew closer to the suggested volume rating.
