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.
My last printer, an Epson, didn't even last 2 years. I now have a Canon S750 printer, about 3 years old. I don't print high volumes, maybe 300 A4 sheets per year, including some photos.I have been quite happy with it, but it has now stopped printing colour correctly.ith hp no problem you change the head and the cartridge. My first epson last for 7 years (i give it to a friend who use it really often...). now i have a laser printer BW and an hp deskjet that I refill, AND if it last 2 months whitout printing ,it runs. well when i decide to use it.
