With the XipPRINT hardware, compressed TIFF files could just be copied to the printer. Why is ipclLib recommended now?
The problem with just sending a TIFF file to the printer using a XipPRINT driver is that corrupt TIFF files can corrupt the print driver. It is much better to send via an ipclLIB application which verifies the TIFF file before sending. This does not mean decompress the file, but interrogate the headers to assure their validity.
