I had a user that was receiving an error when printing to a network shared printer.
It was a Windows Server 2003 Print Server, latest PCL6 drivers. Desktop was running Windows 7 x32.
When a larger document was sent to the printer (sometimes as small as 20 pages, large as 70 pages), it would print the document, but only partially.
The job would stop and would print a page labeled “PCL XL error Subsystem: … ”
On the Windows Server, I edited the properties of the printer that was being shared out.
On the “Advanced Tab”, deselect the checkbox for “Enable Advanced Printing Features”.
Note: Depending on the printer driver, this may remove some features from the software driver.
