According to our information, the difference is that wireless is available on the 135w model and not on the 135 wg.

Yes, it also copies and scans (that's why it's called a multifunction printer). There are three toner options, the 105A, 106A and 107A. The only one sold on Digitec is this one: HP 106A (BK)

I was sent this printer to Switzerland with an EU plug instead of a CH mains plug. None of my complaints were processed or answered. So I had to go to Media Markt to buy a suitable cable to get the printer working. So watch out for all Swiss customers. Do not order any devices from Galaxus!

Hello, Yes it can print and scan. These are the replacement cartridges: HP 105A laser original toner cartridge, black (yield approx. 1000), HP 106A laser original toner cartridge, black (yield approx. 1000), HP 107A laser original toner cartridge, black (yield approx. 1000).

Unfortunately, this printer has no colour. It has a scanner and a black cartridge for 500 sheets. The price of the cartridges ranges from 30 to about 40 francs and prints about 1,000 pages.
