Each of these printers prints single-sided pages, but by adding a "2" to the printer name you can get doubled-sided printing (eg "lumber2" or "paper2").
| Printers: | Lumber (Gates 485) | Palm (Gates 457) | Teak (Gates 285) | Paper (Gates B21) |
| Linux | lpr | lpr | lpr | -- |
| Solaris | lpr + lprm | -- | -- | -- |
| Ultrix | lpr + lprm | lpr + lprm | lpr + lprm | lpr + lprm |
| Xenon | -- | lpr + lprm | lpr + lprm | lpr + lprm |
| Sunburn | lpr + lprm(?) | lpr + lprm | lpr + lprm | lpr + lprm |
"lpr" means you can print; "lprm" means you can remove (your) entries from the print queue.
