The IBM 4245 is a line printer. The Printer Output Unit for the 4245 Models 012 and 020 attaches to the 370 channel interface (byte multiplexer, block multiplexer, or selector channel) for attachment to 4361, 4381, 308X, 3090, S/38 (5381 and 5382) and 9370 processors. Request an RPQ for channel attachment of the 4341. The 4245 Models D12 and D20 attach to the 3174 and 3274 Models 41 and 61 controllers, the 9370 Workstation Controller, and 4361 processor Workstation Adapter and Display/Printer Adapter. The Models T12 and T20 attach via the Twinax interface to AS/400, S/36, S/38, and S/88. Print speed is 1,200 lines per minute (lpm) for Models 012, D12, and T12 with a standard 48-character set printband. Models 020, D20, and T20 are 2,000 lpm with a standard 48-character set printband.
