What version of FoxPro are you using?

In older versions ??? sends the character expression directly to the printer
without incrementing the printer column or row; it was most often used to
send control codes for bolding, line spacing, or other such non-printing
control information. You then end up with the program being customized for
one model of printer.

When the user changes printer, you have to modify the program to accomodate
the new printer. Much better would be to learn the use of FoxPro's built-in
report writer.

HTH,
Randy

hi,

thanks so far.
I use vfp9 sp2
I need to print to a printer port under TerminalServer (windows server 2003
and SBS)
without printer drivers.
(There are no printer drivers available for that ticketprinter and the
layout is not important)

some ideas to your problem:
- install the generic printer driver. It is included in every windows setup, the
naming varies a little between different windows versions (and of course
language). Look for something like "Generic / Text Only"
With this driver, all output is sent directly to the printer without further
driver intervention. Then I would use ??, not ??? and not @ x,y. Use ? only if
you want the CR/LF at the beginning of the line.

- If you want a pure plain text printing, then use ??? instead of @ x,y SAY
because the latter could add some additional spaces or line feeds based on the
different x,y of the commands lines.

Since you can't talk to the printer directly,
@... say might not work as in Foxpro/DOS.

Convert them into ??? or use a report writer.
