Recently bought this motherboard GIGABYTE B360M D2V and Intel. But printer HP LaserJet 1100 connected to the old motherboard via LPT, and in the new it is not. There is cable LPT - USB. When connecting the printer via this cable the printer is installed is added to "Devices and printers" but does not print! What to do and h...

Actually a subject, the language is unimportant as OS

Based on the article Control a lamp via the Internet collect something like that. But faced with a problem the solution of which I can't find for several days. I really hope for a hint or an idea... the Situation is this: With LPT I took only 2 pins: D0 (2) and GND (3). Connected through the resistor for 300 Ohms, to optoco...

Recently decided to make a lock for that door on the actuator. The program is written (when you enter the code on the door, and checking it moves the logical unit to one of the conclusions of the LPT port, and a relay which in turn closes and opens the load), through which he triggers (goes to "open" position). But there is...

Zdrastvuyte. Gathered a CNC machine, on an old laptop with LPT mach3 set up, everything works. Step-dir CNC controller I built for LPT-port on the basis of the l297 and powerful polevikov - works fine. Because the LPT is not everywhere, you want to change the controller. Instead of l297 want to use a microcontroller that w...

Hello! Microelectronics I do not know from a word absolutely , and it's hard to know where to start... Actually, the idea is this: standing somewhere in the room the motion sensor, as I understand it, when it works - there is an open circuit, this signal I want to get on the computer. Now the question is how this data is tr...

You need to connect the old printer, but it has no USB connector, and on the computer, respectively, LPT (((, adapter to order is not an option now, maybe someone knows how to solder?

You must implement the management of the lpt port from a web page. To control the lpt port using pyParallel library. For web Django. As I see it (Maybe there is a more "correct" solution?): On the page of 8 buttons, each responsible for its own pin port. When you press one of the buttons is the number of the pressed butt...

Is it possible to implement this scheme, and if so, tell me where to dig? There is a device, it is possible to send data to the printer (usb or lpt). Need to data is sent not to the printer and to the computer for subsequent processing. As you know, there are 2 problemsThe problem of connection, for example a simple usb cab...

Good time of day. Tell me, how to control lpt ports in Windows using python? Under "manage" I mean to see(to address) of precisely those lpt ports which are connected to any devices. Thank you.
