[Phpprintipp] Printing to Epson SX440W network printer

[address@hidden]

Dear list,
I'd like to print (even if it's just text files) from a PHP script to a 
standalone network printer (Epson Stylus SX440W EPSON14E42A) configured 
with static IP address 192.168.0.13.

I'm using XAMPP webserver on localhost (localhost is 192.168.0.40).

I placed BasicIPP.php CupsPrintIPP.php ExtendedPrintIPP.php 
http_class.php PrintIPP.php in the "printipp" directory.

This is the code:

require_once('printipp/PrintIPP.php');
$ipp = new PrintIPP();
$ipp->setHost("192.168.0.13");
$ipp->setPrinterURI("ipp://192.168.0.13:631/printer");
$ipp->setData("testdata.txt");
$ipp->printJob();

Tested printer uri:

ipp://192.168.0.13:631/epson

ipp://192.168.0.13:631/printer/epson

ipp://192.168.0.13:631/printer/ipp

ipp://192.168.0.13:631/ipp

ipp://192.168.0.13:631/printers/EPSON1AE42A_(Epson_Stylus_SX440)

/printers/EPSON1AE42A

/printers/epson

...

I always get "Warning: server responds http/1.1 404 not found"

Can I make this work somehow?

Thanks
