printer_open() function gives me a warning couldn't connect to the printer []

Bismuth

Hi All!

I have a problem with my code. When i call the printer_open() function it gives me a warning couldn't connect to the printer []. I have a printer installed in my computer and it works fine but when I run my script that has a printer_open() function with the default parameter it gives me such warning. I am using iis web server, ms sql, and php 4.3.8 in windows 2000 server. In my php.ini i uncommented the extension=php_printer.dll and the i placed the php_printer.dll in the extension directory. What's the problem with this?
Anybody's help is highly appreciated...

We'll more than likely need to view the code before helping you.

<?
$fp=printer_open();
?>

Hi all!

I want to print the books issued on that particularly day and I'm using php to print to the printer. I initially put a code printer_open() in the first statement but it fails to open. Any idea on how am I going to fix this or any idea on what kind of functions do I used in order to print this book issued?

Your help is highly appreciated...

Bismuth.

Have you specified a default printer? Have you tried supplying the printer's name?

Have you specified a default printer? Have you tried supplying the printer's name?

Calling a printer_open() without parameter is considered as calling a default printer according to the php manual. I have a printer installed in my PC and I set it as a default printer. I tried supplying the printer's name but it's still the same warning I get "warning couldn't connect to the printer [my printer name]". I didn't know what I'm going to do. Is there something wrong with my OS(Windows 2000 Server) I'm using? In php.ini only extension=php_printer.dll i uncommented and all configuration are default except the [sessions] category. Is there any way of doing printing in php besides printer_open() function that we can select what kind of fonts we used and we can set the size of the fonts?

I already got it by supplying printer's name. Only an extra single character of printer's name makes a warning. But now my problem is I have a lot of printer_write() or even printer_draw_text() function in one printing function. When I call the printing function it prints page by page. Here's my code:

function printIssue() {
$handle=printer_open("EPSON LX-300");
$font=printer_create_font("Draft Condensed",25,6,PRINTER_FW_THIN,false,false,false,0);
printer_select_font($handle,$font);
printer_write($handle,"Library & Learning Resource Center");
printer_write($handle,$name);
printer_write($handle,$address);
printer_write($handle,$book_borrowed);
printer_delete_font($font);
printer_close($handle);
}

Why it prints "Library & Learning Resource Center" on one page and $name on the other page and so on...
When I call this function my 4 sheet of papers are printed 1 line each. I want to print this line by line and not page by page. Any idea?

From your description of what you did with php.ini I can't tell if you set the "printer.default_printer" option in that file; PHP will try to detect a printer if that's not specified, but may not succeed. (See [man]printer#configuration[/man] for more information.

printer_write($handle,"Library & Learning Resource Center
$name
$address
$book_borrowed");

Perhaps? Or maye use [man]printer_start_page/man?

Hi,

one of the user comments in the manual

http://php.us.themoes.org/manual/en/function.printer-draw-text.php

contains an example using printer-draw-text with all the page stuff and font selection.

Thanks a lot to everyone. It works fine using the printer_draw_text().
