Some quilters have used laser printers for Inklingo but I do not recommend it for a few reasons.
A laser printer uses toner, not ink, and it uses heat. If you put fabric and freezer paper into a laser printer it will probably ruin the printer because the plastic coating on the freezer paper will melt and create a mess that cannot be repaired.
If you decide to risk it, please be sure to follow the instructions to print test pages, so you know which colors of toner do not smear or show on the front. Toner is not the same as ink.
Luckily, you can probably pick up a Canon Inkjet on sale for less than $50. (You would want to spend more if you want to print photos.) You can have more than one printer connected to your computer at the same time. Inklingo uses a tiny amount of ink, so if Inklingo is your primary use for the Inkjet, the ink will last a long time.
