Есть вопрос! — HP 1020, CUPS и многостраничные документы Word 2003

Система - Ubuntu Server 10.04, печать через CUPS на HP 1020, hplip 3.10.9.
При печати многостраничных документов (более 10 листов) у системы сносит крышу. Печатает произвольные листы (например 1-5 потом 10-15 и т.д.) в количестве 3-5 экземпляров. В чем может быть проблема?

Up: проблемный порт USB.
Всем спасибо.
