| 4 | lp \- line printer | |
| 5 | .SH SYNOPSIS | |
| 6 | .B "device lp0 at uba0 csr 0177514 vector lpintr" | |
| 7 | .SH DESCRIPTION | |
| 8 | .I Lp | |
| 9 | provides the interface to any of the standard | |
| 10 | DEC line printers on an LP-11 parallel interface. | |
| 11 | When it is opened or closed, a suitable number | |
| 12 | of page ejects is generated. | |
| 13 | Bytes written are printed. | |
| 14 | .PP | |
| 15 | The unit number of the printer is specified by the minor device | |
| 16 | after removing the low 3 bits, which act as per-device parameters. | |
| 17 | Currently only the lowest of the low three bits is interpreted: | |
| 18 | if it is set, the device is treated as having a 64-character set, | |
| 19 | rather than a full 96-character set. | |
| 20 | In the resulting half-ASCII mode, lower case letters are turned | |
| 21 | into upper case and certain characters are escaped according to | |
| 22 | the following table: | |

| 51 | The driver correctly interprets | |
| 52 | carriage returns, backspaces, tabs, and form feeds. | |
| 53 | Lines longer than the maximum page width are truncated. | |
| 54 | The default page width is 132 columns. | |
| 55 | This may be overridden by specifying, for example, ``flags 256'' . | |
