Description: I picked this thermal printer up - Virtually brand new - From a radio rally for next to nothing, and I instantly started wondering whether I could connect it to my A1200D for printing off item lists for parts storage - The problem being that the printer has a single-sided 17 pin edge connector for the interface. About a week later the MDF stand on which the printer can be seen was finished, complete with adaptor assembly to a standard printer Centronix connector. What’s with the "Alarm reset" button? The idea is that, due to this printer being 7-bit only, if an 8-bit character was ever sent to the printer, the printer may start churning out false information. A small circuit consisting of 4 NAND gates detects when the /STROBE line and the 8th data line are active together, sets a latch circuit, and sounds the buzzer warning of a invalid character. The corresponding reset button resets the alarm. ...As hard as I try, I can't seem to even get an 8-bit character to be deliberately sent to the printer to test the alarm! All the characters appear to of already been substituted in the Amiga's OS for a similar character. Sigh :roll: . Btw, this printer is dated December 1984, thus predating the A1000 - And it’s still working! :crazy: Printer model: Able Systems OMNIPRINT OM20 Picture Stats: Views: 1117 Filesize: 272.66kB Height: 768 Width: 1024 Posted by: Hodgkinson at December 27, 2007, 05:48:19 PM Image Linking Codes

| Hodgkinson Posts:1080 | February 10, 2008, 09:01:40 PM Thanks for the comment ;-) I actually thought about adding an acrylic cover over the top of the set-up, but I figured that it would be more hassle than its worth as it would obstruct changing and loading the paper drum...Its a real faff to get the paper to go into the printer head assembly...You need to get the angle just right for it to feed through :-) Hodgkinson. EDIT: It's now got a acrylic cover over the electronics :-D |
