Amazon.com has lots, or a best buy. Maybe an office supply store. You could also try Craigslist.org if you don't mind buying used. Wal mart sells them if all else fails.
You can find the cheapest laser cartridge for your printer at amazon.com. They offer a wide variety of affordable ink and laser cartridges for every printer there is.
If you have an HP laser printer, I suggest you buy it directly from HP online store. I find it cheaper to get laser printer cartridges from them for my HP laser printer. If you have a different brand of laser printer, amazon is a good place to start if you're looking for a cheaper laser printer cartridge.
A good deal on a compact laser printer can be found on the Amazon website. They have a Brother HL2270DW Compact Laser Printer with Wireless Networking and Duplex listed for $109.99.
You might think that your search for the right laser printer cartridge is not going to show you many differences, but you will probably find that the brand of printer you have produces the best cartridges for that machine. This is normally because they know what works best on your specific printer.
The laser printer was invented in 1969 by Gary Starkweather at Xerox. The first commercial laser printer, the Xerox 9700, was released in 1977.
Choosing the best laser printer comes down to three things: print volume, running cost, and reliability. First, check how many pages you print monthly—entry models are fine for under ~500 pages, but heavier use needs a higher duty cycle. Second, compare toner cost per page, not just the printer price; cheap printers often have expensive cartridges. Third, look for features like duplex printing, Wi-Fi, and easy driver support. I’ve found Ricoh printers hit a sweet spot here. They’re built more like office machines than disposable gadgets—solid drums, long-life toner, and very stable networking. The upfront price might be slightly higher than bargain brands, but the cost per print and durability make them cheaper in the long run, especially if you want a “set it and forget it” printer that lasts years.
"I could not find any information online as far as the possibility of replacing the actual laser on a laser printer. You can go to the web site of the manufacturer of your printer, and see if they sell lasers as a replacement part."
It is not challenging to find a retail store that sells color laser printers from Brother. One can purchase a color laser printer of the brand Brother by going to Office Max.
If the vellum is rated for a laser printer, it shouldn't be a problem. You do NOT want to use inkjet paper in a laser printer, or vice-versa.
RIP.
Laser printers use a drum and toner in the printing process.
