I think that Angelo is speaking about USB->Parallel adapters being used on computers that lack a physical parallel port. I believe that this question has come up before, and the answer was NO, it doesn't work. I recommended using a PCI parallel port card, but Angelo is working with a laptop. 73, Kyle K0KN Olathe, KS Allstar 2210-2219 --- Original Message --- I was wondering if anyone has tried a USB Printer interface with the PRLP interface with Asterisk??? Does ACID address the USB adapter??? 7 3 de Angelo
