Hi Petr and everyones,
a = _NEWIMAGE(640, 900, 32)
_DEST a
CLS , _RGB32(255, 255, 255) 'white background
COLOR _RGB32(0, 0, 0), _RGB32(255, 255, 255)
PRINT "Test"
_PRINTIMAGE a
That program prints a blank sheet.
As I mentioned, it only happens with a computer. I have tried on 3 computers connected to the same printer, and even with another printer, and it works fine, except with that computer. As I mentioned, it has Windows 7 SP1 64 bits. In another computer with windows 7 SP1 of 32 bits and another one with windows 10, they work perfectly.
It is not a program problem, but the _PRINTIMAGE command, which does not work on that computer.
