As it was a dead-end device (no through port), it could only be used with interfaces such as memory cards which had a through port. Released in December 1984 at a price of £86.25 (£50 plus VAT), the Q-PI Interface performed well enough in its day as a parallel printer connection system, though these were quickly superceded by serial-parallel converter devices by other companies, as it was impossible to use a disk interface with the Q-Π due to the lack of through port. Oddly, the parallel port uses an IDC-34 way connector, rather than a standard 25 pin DB connector. We have not come across the correct lead to use this interface. The cable was an additional £11.50 on top of the price of the interface! No manual - simply use OPEN #3,par: PRINT #3, 'Hello World': CLOSE #3 It also adds the command DUMP_SCR to send a screen dump to a printer (presumably EPSON compatible). ---- {{qlwiki:q-pi-interface.jpg?direct&240x180 |CST Q-Pi Printer Interface}} Title: **CST Q-PI Printer Module**\\ Interface Type: Centronics Printer Interface\\ Connection: Sinclair QL Expansion Port\\ Through-Connector: NO\\ Manufacturer: [[qlwiki:CST]]\\ Year First Sold: 1984\\ Original Price: £86.25 \\ Reviews: QL User (December 1984/January 1985)\\ Download Manual: Unknown\\ qlwiki/cst_qpi_printer_module.txt Last modified: 2023/08/25 12:23by 127.0.0.1
