[PHP] Printing ASCII on Linux Server

2002-09-02 Thread Mingshuo Lin 

I am trying to printout some ASCII Text (using LPR,
script see below) to a IBM Proprinter compatible
dot-matrix printer, on a server running Linux.

Printing works fine, however 2 problems:

1. linefeed (\n) doesn't work

2. escape sequences to print BOLD, ITALIC, UNDERLINE,
NARROW don't work

Any help is appreciated!!

Thanks!

$print_string .= $narrow_on. narrow.
$narrow_off. $linefeed;



// 3. PRINT ON LINUX SERVER

$lp = popen(lpr -Plp1, w);
$bytes_written = fwrite($lp, $print_string);
pclose($lp);

Does printing work properly when printing from a file (made up from your 
code here), not from php? If not then its a print setup problem not a 
php problem. I'd check out your printing setup and if its a print setup 
problem then check for any bugs/upgrades.
