Server Side printing with PHP

Copy linkTweet thisAlerts:
Jul 26.2005

We currently have an internal web application to process production orders. We are in need of some ‘automated’ printing. When an order is created/processed, it will need to automatically print out a label to one of the printers in the warehouse. Sometimes each order will print 10-20 labels. The existing web application is MySQL and PHP based.

Does anyone know of a way to have the server automatically print labels without prompting the user?

I have looked into the [URL=http://us3.php.net/printer]php_printer.dll[/URL]… but have had no luck with the installation. The server is Windows 2000 running Apache web server.

Any help or thoughts would be appreciated.

What problems with installation are you having?

@JerryJrauthorJul 26.2005 — Thanks for the quick reply.

The original settings in the php.ini settings were:

extension_dir = ./ ; directory in which the loadable extensions

;extension=php_printer.dll

I changed them to:

extension_dir = c:phpextensions ; directory in which the loadable extensions

extension=php_printer.dll

I tried restarting apache, but failed. So I restarted the server and apache did not start once again. I then changed the settings back to the original and restarted once more and apache was back up.

That about puts me where I am at right now.

@CompGeek01Jul 26.2005 — Did you get any kind of error message when you tried to start up the server?

try changing the line extension_dir to:

extension_dir = c:/php/extensions/

@JerryJrauthorJul 26.2005 — Error message from yesterday was:

PHP Warning: Unable to load dynamic library 'c:phpextensions/php_printer.dll' - The specified module could not be found.

in Unknown on line 0

** Just found the error log **

I will try your settings from the previous post.

@CompGeek01Jul 26.2005 — Ok, with the error log this should work:

extension_dir = c:/php/extensions

make sure that the slashes are forward slashes and there is no trailing slash...it seems to make one for you/

@JerryJrauthorJul 26.2005 — Well that was a no go. Apache did not give an error message this time, and did not start once again. I made the changes back and restarted once again. The server came back up.

@CompGeek01Jul 26.2005 — Nothing in the error log at all? hm.

@JerryJrauthorJul 26.2005 — Yeah, nothing at all. And the web server was not responding from my browser. Its really odd. I did update the php_printer.dll file also. The exising file was 36kb and the new one is 48kb. Not sure if that could make a difference. I figured the one that was there was outdated.
