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!
For example, if you printed 3,000 pages in January, 3,300 in February and 2,800 in March, the average is 3,000 plus 3,300 plus 2,800, divided by 3, or 3,033 pages per month. Multiply this figure by your per-page cost to determine the average monthly cost of laser printing.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.
