I have run Alpha for 10 years without any printer problems. Recently upgraded to V7. My application includes some routines that print on an old Epson LX850 dot matrix. They print ok but the whole system slows up, screen blanks etc., and can't do anything else until the print run finishes. Never had this problem with A5V5 on XP. Can anyone help? I have a good Acer pc with plenty of memory.
