Parallel Port to USB? was created by erkanmdr
Hi everyone!
I have a control board with LPT output. But I want it to run on laptops.
There are such products on the market:
They may be able to?
I'm waiting for your ideas. Thanks! (My Controller Card: 5 axis CNC Breakout Board Card MACH3/EMC2/KCAM4 )

Sorry, just does not work with Linuxcnc
Laptops are not a good idea anyway, because they have lots of power saving interrupts etc which affect latency.
USB does not cut it, because there are no guarantees of when the signal will get through.
(search the posts for full details of why not, several long and very detailed explanations)
The cable you show is to enable people to use old printers with a USB port.
I expect it has windoze drivers that will also not work with linux
In any case printing does not require any sort of real latency, the printer will just wait until the data is transmitted,
so USB is fine for that.
