OnPaper: the direct print solution

OnPaper

Is the innovative printing strategy enabling mobile document printing on any printer supporting the PTP (Photo Transfer Protocol).

The principle

If the printer can be connected to a camera you can print your documents with OnPaper:

  • No driver is needed
  • No need to recognise the printer brand, model, type
  • No need to download drivers
  • No need cloud connection, we take care of your privacy

How it works

With OnPaper you should just know these few information:

  • Paper size (Letter, A4, A5, …)
  • The kind of printer: Black and white InkJet or Laser, Photographic printer

That’s all. Then you select the document from your mobile device and share it with OnPaper app. In a bunch of seconds you have the image of your document ready for printing.

Documents and images converted for printing are saved in the folder OnPaper under your Image Gallery for future reuse or deletion.

The Vintage 555 button debouncer

Buttons and tactile switches are frequently used in many projects involving micro controllers; one of the most frequent issue we met is related to unwanted multiple transitions when the button is pressed once.

Tactile switches, as well as push buttons are mechanical components subject to the problem of bouncing. When a button is connected to a digital GPIO input pin (i.e. an Arduino pin configured as INPUT) we ideally expect that when the button is pressed we get only one high digital signal; unfortunately this rarely happens. During the mechanical movement the physical material vibrates affecting the voltage and the transitions between the On/Off status are not so clear as we usually need. Micro controllers and FPGA are fast enough reading the microseconds oscillations when the button is pressed, resulting multiple readings while apparently we are pressing the button only once.
