1 From the secondhand account, the reader gets more background information about what the Oregon Trail was. 2  From the firsthand account, the reader gets a better understanding why it was so dangerous.
Printers generally age more by the number of pages printed rather than by pure years. The rule of thumb has always been whatever the recommended volume is (for instance 5000 pages per month for a P3005) multiplied by say five or six years so about 300,000 pages would be the life expectancy of the printer.
Direct thermal printers use heat instead of ink and are typically smaller, quieter, faster, and more energy-efficient than dot-matrix printers. The GC420d is a standard level desktop printer that has a maximum print speed of 4 per second at 203 dpi (dots per inch) and can print labels up to 39 long. The 32-bit processor combined with 8 MB of SDRAM memory and 8 MB of flash memory offers faster first label printing with extensive media graphics storage.
