| 231253 | 2004-04-22 10:46:00 | I have a new HP printer with an automatic paper sensor. Tonight for the first time I tried to print on black cardboard - the printer's LCD screen had the error message "Out Of Paper". Obviously the sensor can't see black. Before I try HP, has anyone struck this, and is there a work-around? | Shortstop (632) | ||

| 231255 | 2004-04-23 10:58:00 | I was thinking of green or gold. Incidentally,why can't you print white text on black card? | Shortstop (632) | ||
| 231256 | 2004-04-23 11:09:00 | Ink uses "summative" colouring, with all colours used = black. There is no combination of colours that will print white in an inkjet used for normal printing. To print white would equate to no ink, which would be invisible unless the background was printed a colour at the same time, naturally. You could print a black or coloured document with white writing as long as the black background was produced at the time of printing the white text. The text is simply an absence of ink. Basically, black media is unable to be used in many printers due to sensor detection, and unlikely to be printed correctly anyway due to ink technologies. |

| 231257 | 2004-04-24 03:15:00 | You could try putting a band of removable cellotape on the leading edge . It might reflect enough light for the sensor . Or a narrow strip of white paper held on with tape . (If you haven't got removable tape -- I found it at Warehouse Stationery -- ordinary tape might come off with not to much surface damage, or you might be able to trim off that edge) . Opaque inks are probably available . . . somewhere . :D |

| 231258 | 2004-04-24 09:01:00 | Thanks Godfather and Graham L - you've furthered my education. The tape would be on the non-printing side, but I should probably give up for something more profitable. On another tack - Godfather, the printer is USB - shows up as a Removable Disc, and doesn't support Hibernation. By turning off the printer I can get my laptop to Hibernate, but is there any other way? |

| 231259 | 2004-04-24 11:49:00 | If it shows up as a removeable disk, one can only suppose it has camera card reader slots built in . But you don't say what sort it is, and the crystal ball has failed to see it . You may need to refer to the printer documentation, as not all card readers support hibernation . If its a card reader . |

| 231260 | 2004-04-25 10:47:00 | Yes, GF. The printer has a card reader, but the documentation doesn't say anything about being a card reader inhibiting Hibernation. | Shortstop (632) | ||
| 231261 | 2004-04-25 19:00:00 | It may be a user setting? Some card readers offer optional continuous voltage support for some cards if enabled, and this would certainly stop hibernation. |
