I have an HP LJ4 on an NT 4.0 network with Win 98 workstations. Frequently, but not always, the device will print the first page of a document, then just spits out endless pages with 2 or 3 lines of garbage. The document type doesn't seem to matter--Word 2000, pdf's, internet files. The documents will print on other HP models. It seems to happen more often when multiple documents are queued in the spooler. Any ideas?
