the installation of color laser printer is growing every year. more and more people use laser printer to print photography and disappoint in poor printing quality or paper jam. what is problem happening when using laser printer for photographic printing?

paper thickness and color saturation:
basically, the color calibration of laser printer is based on common paper (80~100gsm). if increasing photo paper thickness (for example, the paper of photographic development system is over 180gsm), the color saturation will be reduced. how to avoid loss color saturation when increasing paper thickness?

printing speed:
slow down printing speed can take more time for toner transfer and increasing color saturation. in the market, there are many different types of different printing speed such as 4~5ppm (pages per minute), 16ppm and over 20ppm. fortunately, printing speed is possible to be controlled by selection icon of paper material. recommended speed is 106~160gsm.

thermal stress:
many people recommend glossy photo paper or premium paper for laser photographic printing. be careful! the heating temperature of fuser can rise up to 200 degree c during printing. the potential risk of thermal stress is possible to melt-down the coating material of paper surface or crack happening. particular, printing is operating at low speed. thickness again! the thickness of those products is over 80~100gsm.

paper polarity:
another methodology is how to change physical characteristic of paper surface to improve toner transfer. fortunately, toner is negative polarity of almost laser printers, it is possible to spray electrical positive charges on the paper surface and conduct more toner to paper surface to increase toner density and color saturation as well.

resolution:
due to toner is dry powder in natural, the paper has no connection with resolution. the image resolution is decided by printer engine and printing language. 600 x 600 dpi can offer remarkable picture image quality. 1200 x 1200 and 2400 x 2400 dpi will increase more grades of gray level and improve better cubic effect.

glossy:
keep in mind! toner is dry powder. whatever your paper is high glossy or brightness, the surface of photo paper is covered by toner after printing. if it can present glossy, that means the toner density is not enough and the color of printing quality is very light. actually, toner embraces wax inside and it can offer brightness after printer.

moisture:
moisture tends to make pulp fibre expansion, raising paper thickness and uneven roughness. coating skill perhaps is one of solutions to isolate moisture in air. apply synthetic paper to replace pulp paper is a good alternative to resist moisture completely.

testing:
the testing had done with hp clj 2500/2550/3700/4600/5500, epson aculaser 900/1100/1900/3000/4000/4100 and xerox dc12/6060.

low end printer:
such as hp clj 2550l, the price is around usd 400, 600 x 600 dpi printer engine with pcl 6. the companies of recycling cartridge & refilling toner can help you to cut 20% of consumables cost.
