A wide format laser printer is a great way to get the flexibility of being able to print larger documents along with the speed and incredibly high quality that laser printers bring to the office.
These days, the most common size is 11 inches by 17 inches which is often called the tabloid size.
This is dramatically larger than most normal printers and is actually two letter sized pieces of paper side by side! This way, you can print your documents at full size instead of shrinking them down to fit on smaller paper.
This can also allow you to print banners and posters that will bring some cheer to the office as well.
Most wide format laser printers are only black and white.
If you want to print large documents in color, this will usually cost you dramatically more since a full color large format laser printer is very expensive.
A large ink jet may be a better choice if you just need to print out a few color prints every once in a while but still have the majority of your printing be black and white.
Be careful as the toner cartridges and paper for these larger printers can be a bit more expensive: The toner cartridges are usually 11 inches big and 11 by 17 inch paper costs a lot more than normal printer paper because it is comparatively much more rare and less commonly used in offices.
You can often buy a wide format laser more cheaply by buying it pre-owned.
