printer control code

Dear Sir:

I have a vb program which print data to dot matrix printer STAR SP 300.
In programmer's menual there is table for control codes used for charactor setting.
How can I trigger 1/6 inches line feed using control codes in vb 5.0.

Example:

Control codes : <ESC> "z" "1"
Hexadecimal codes: 1B 7A 31
Function: set 1/6 inch line feed

In character code table <ESC> is 27,"z" is 122, "1" is 49.

But now how to carry out 'Set 1/6 inch line feed' function using Printer.print ????

I try:
Printer.print chr$(27) +chr$(122)+chr$(49)

print only three characters.

my best regards,
I need answer ASAP.

You simply don't do it this way.

Use the windows drivers for the printer and let it control the printer. IT will work correctly no matter what.

Also, 1/6" line spacing is the *DEFAULT* on almost all printers (as is 10CPI). You shouldn't have to set it no matter what.

Windows isolates your program from the printers internal characteristics. If you use the Printer.CurrentY parameter you can print text at any spacing you want. Windows will handle figuring out how to convert your commands to the commands for any specific printer. Your code will be printer independent.

This is a major departure from DOS.

Printer control parameters include:

Printer.CurrentX/Y
Printer.TextWidth()
Printer.TextHeight()
Printer.Bold
Printer.Underline
Printer.Italic

etc. As you send these commands in your program windows will handle the conversion.

Your answer is rejected.
I have to use control code to enabel a different funtion.
Not only "Set 1/6 inch line feed", but also:
1. initialize printer
2. clear printer buffer
3. tigger auto-cutter driver
...
....
Control code will be printer dependent.

By the way , do you have experience with STAR SP 300 series printer? The biggest problem is that I can not tigger the printer to cut the paper using control code. That is not done by printer driver, although I have set the printer in Auto-cutting model already.

What driver are you using?

Latest seems to be dated April 99, V3.4. If set to ticket mode it should cut every time it gets a formfeed.
