To talk to the parallel port you can do the following (it assumes there is some device like a printer attached)


Open "LPT1:" For Output Access Write As #1
Print #1, Chr(27); Chr(107); Chr(3); 'font
Print #1, Chr(27); Chr(77); 'pitch 12
Print #1, Chr(27); Chr(120); Chr(1); 'letter quality
Print #1, Text1.Text
Close #1
