Laser Printer Cost Advantages. Consider that an entry level business Color Laser printer can be bought for less than $250. If one uses the same cost comparison method, the cost is less than $0.16 per page.($231 street price divided by 1500 sheets = $0.154 per page).The savings become even greater when the costs of the printer and subsequent high capacity replacement toner cartridges are used and factored in over a 3 year period.tâs not uncommon for inkjet cost per page analyses to work out to be $0.25 to more than a $1 per page. Be sure to consider all of the costs when you attempt to compare printers! For a relatively low volume of 50 to 100 pages a month, the supply costs arenât too bad!
Divide the cost by the printerâs page count to get a cost per page figure. For a $100 toner cartridge and a page count of 10,000, $100 divided by 10,000 equals $0.01 or 1 cent per page.aintenance items tend to figure less in your long-term per-page printing costs, but are necessary for an accurate number. If the cost of paper is 1.2 cents per page, toner is 1 cent, and the printer drum is 0.27 cents, the total per-page cost is 2.47 cents. Step 6.
