Issue in Printing Data for USB Printer(HP1112 - PCL3) with LPC1769

[girishgujar]

Dear Sir,

             We are working on - USB Printer (HP1112) with LPC-1769 (Using USB Hostlite  sample code  mcb1700.code_.bundle.lpc1769.lpcxpresso\USBHostLite). 

As far as enumeration part for usb printer, we have successfully added it.

Also we are able to read all descriptors for Printers,

Device,Configuration,Interface,Endpoint (Both Bulk In & Bulk Out).

But we are facing issue in data transmission to Printer. ( Logic for Printing Dummy data, after enumeration)

Also we wants to use Bulk transfer mode for data Printing.

Kindly Guide us..

Kindly revert if any information is required

Thanks & Regards,

How can it be a Print Nightmare if only one out of twenty-five printers is affected?

Wouldn't that bring down all of our network printers here are on the print server, or at the very least all of the same model as the one that's broken?

The issue must be server-side, but no upgrades had been installed on the server when the problem began.
