Wow! I thought I was the only one daft enough to buy such a monster from my local 'Government Surplus' dealer. :-) I had to rewire the parallel interface (including adding an inverter or two) to make it 'Centronics Compatable' for connecting to my Transam Tuscan S100 Bus machine. It only printed unidirectionally but the bi-directional version wouldn't have sped it up very much since the carriage return action was so swift it was more akin to its predecessor, a Teletype Model 33 ASR. I think it eventually got replaced by an HP Deskjet 960C and I eventually hauled it out of my basement 'shack' to sneak it onto the back of an untaxed wagon that had been illegally parked across the road for the past couple of months ( I thought that if we'd had to put up with this eyesore which was seemingly being pointedly ignored by the authorities for the last two months or so, I might as well get some utility out of it :-) That was replaced by a much smaller dot matrix printer that I only stopped using when I got the first inkjet printer that produced a much better result and cost peanuts. I gave up on inkjets long before they 'got cheap'. The plain fact is I simply didn't do enough printing to stop the heads clogging up between jobs. I'd have done much better using a good old fashioned impact dot matrix or daisywheel printer and a small box of re-inkable ribbons (cartridge or open spool). The price of the consumables for all inkjet printers is hundreds of times greater than that of the impact based technology which, imho, is a total disgrace. I stopped using that when PCs no longer supported the interface. Presumably you're talking about Major OEM branded ready built PCs like Dell and HP/Compaq et al. The latest MoBos I bought brand new about four years ago still sported the centronics/LPT header to connect a printer connector backplate to. I suspect this may no longer be true today. I guess I'll find out in a year or so's time when I next upgrade my machines. I replaced that with a decent USB inkjet and had that work fine for years. Its just had an electronics card failure and since I had picked up a spare at a garage sale for just $5 it wasn't worth even changing a failed cap. It's the only one that has actually died rather than become obsolete. The last inkjet I purchased was a Canon Pixma iP4000 about 5 or 6 years ago which I'd specifically chosen for it's inclusion of the centronics interface (to match a printserver) and the ability to print onto CD-R /DVD-R printable media. I only renewed the 5 ink tanks twice using cheap compatable carts before I realised home printing with inkjet technology had become a mug's game (and this was just for black ink printing, no colour photo follies). I really only used it to print optical disk media labels to make them look a little more presentable than the freehand permanent marker labelling I had used. I only needed to print in black ink but, it turns out that the black ink cart is totally ignored when printing on optical disks and the photocolour 'black' mix is forced onto the user. Once I realised there was no way to get around this reliance on the colour carts to print onto optical media, its days as a printer were numbered until I finally finished off the black ink printing to paper. Now it just sits on it's little table in mute testament to the futility of inkjet printer technology as sold to the gullible consumer by the self destructive manufacturers. I'm sure I can't be in a minority in this regard. We've had a couple of mono laser printers connected to the LAN over the past 5 or 6 years, courtesy of my son, now replaced by a colour laser, also purchased by him. This nicely serves our very modest printing needs. Any photos that I might deem worthwhile getting printed will be dealt with by the likes of Asda or Max Spielman (or whoever) where proper photo printing technology will provide prints at least as colourfast as the traditional photo printing from film media (the same chemistry just raster scanned with laser beams instead of directly projecting an image from a colour negative). In my opinion, no home inkjet photocolour grade printer can compete for cost and quality when asked to print photos. Once you've cast that 'advantage' aside, there's no point in wasting money on another inkjet except, perhaps, on one designed specifically for printing to optical media using cheap ink carts (preferably able to use a dedicated black ink when monochrome is all that is needed rather than force you to consume an expensive set of colour carts to print the job in photo black). However, optical media seems to be going the way of the Dodo (afaiac) so maybe not. I suppose we're still going to have to 'fiddle' our own fixes to the 'consumerism' driven 'planned obsolescence' of toner carts that rely on a counter to prematurely declare exhaustion (in one case, according to the recent BBC programme, "The Men Who Made Us Spend", by a 'safety margin' factor of three!). I've no doubt the printer manufacturers will continue to erode durability of laser printers and carts in their never ending quest to shake down their 'consumer' and milk the suckers[1] for all their worth. The way the Printer Manufacturers are carrying on, the dream of a "Paperless Office" might finally come true a lot sooner than anyone would have expected! :-) [1] Specifically, the suckers referred to in PT Barnum's "There's one born every minute" quotation that seems to have been taken to heart by globalised industries and manufacturers. -- J B Good |

Wow! I thought I was the only one daft enough to buy such a monster from my local 'Government Surplus' dealer. :-) I bought mine new, but I was flogging DEC LSI-11s with them and other hardware, mostly to accountants and operations like that. The LS120 was much heavier and I was never actually stupid enough to try putting one of those into the back of the Golf by myself. I had to rewire the parallel interface (including adding an inverter or two) to make it 'Centronics Compatable' for connecting to my Transam Tuscan S100 Bus machine. I used mine on the DEC LSI-11 that I also had at home, serial. It only printed unidirectionally but the bi-directional version wouldn't have sped it up very much since the carriage return action was so swift it was more akin to its predecessor, a Teletype Model 33 ASR. I didn't have one of those at home, just at work. I think it eventually got replaced by an HP Deskjet 960C Mine was initially replaced by an LA50 on the DEC Rainbow that I added later. and I eventually hauled it out of my basement 'shack' to sneak it onto the back of an untaxed wagon that had been illegally parked across the road for the past couple of months ( I thought that if we'd had to put up with this eyesore which was seemingly being pointedly ignored by the authorities for the last two months or so, I might as well get some utility out of it :-) I've still got at least one LA120 or something in the big pile of stuff. That was replaced by a much smaller dot matrix printer that I only stopped using when I got the first inkjet printer that produced a much better result and cost peanuts. I gave up on inkjets long before they 'got cheap'. The plain fact is I simply didn't do enough printing to stop the heads clogging up between jobs. I likely print even less than you do and don't find that the Canon ip3000 clogs up at all. I'd have done much better using a good old fashioned impact dot matrix or daisywheel printer and a small box of re-inkable ribbons (cartridge or open spool). I wouldn't, basically because I did print quite a few CDs and DVDs. The price of the consumables for all inkjet printers is hundreds of times greater than that of the impact based technology Not when you use the cheapest generic carts off ebay. They in fact cost a lot less than the ribbons for the LA50 used to. It still works but I haven't used it for decades now. which, imho, is a total disgrace. That's why I deliberately bought one of the last of the Canons that doesn't use chipped carts, for the very low price on ebay. I stopped using that when PCs no longer supported the interface. Presumably you're talking about Major OEM branded ready built PCs like Dell and HP/Compaq et al. No, I have always assembled my own using components. The latest MoBos I bought brand new about four years ago still sported the centronics/LPT header to connect a printer connector backplate to. My latest doesn't. Is only a year or so old. I suspect this may no longer be true today. Yeah, it wasn't when I was picking a motherboard, at least with the other things I wanted. I guess I'll find out in a year or so's time when I next upgrade my machines. I replaced that with a decent USB inkjet and had that work fine for years. Its just had an electronics card failure and since I had picked up a spare at a garage sale for just $5 it wasn't worth even changing a failed cap.

The last inkjet I purchased was a Canon Pixma iP4000 about 5 or 6 years ago which I'd specifically chosen for it's inclusion of the centronics interface (to match a printserver) and the ability to print onto CD-R /DVD-R printable media. Yeah, that's the last is the main reason I changed from the previous BJC-4310SP which likely still works fine. I only renewed the 5 ink tanks twice using cheap compatable carts before I realised home printing with inkjet technology had become a mug's game I don't believe that, particularly for printing on CDs and DVDs. (and this was just for black ink printing, no colour photo follies). I do prefer to print colored stuff colored. I don't print photos. I really only used it to print optical disk media labels to make them look a little more presentable than the freehand permanent marker labelling I had used. Yeah, I did it for that reason too. My writing is so bad that people would whinge about the product key. I only needed to print in black ink but, it turns out that the black ink cart is totally ignored when printing on optical disks and the photocolour 'black' mix is forced onto the user. I don't get that with the ip3000. I normally print in blue tho for no particular reason, just looks better than black on CDs and DVDs. Once I realised there was no way to get around this reliance on the colour carts to print onto optical media, its days as a printer were numbered until I finally finished off the black ink printing to paper. Now it just sits on it's little table in mute testament to the futility of inkjet printer technology as sold to the gullible consumer by the self destructive manufacturers. I'm sure I can't be in a minority in this regard. I still print a bit of stuff, but mostly for others who don't have a printer. We've had a couple of mono laser printers connected to the LAN over the past 5 or 6 years, courtesy of my son, now replaced by a colour laser, also purchased by him. This nicely serves our very modest printing needs. I don't print enough to warrant feeding one of those even if I got one for peanuts in a garage/yard sale and they don't print to CDs and DVDs. I print much more of those than I ever print on paper for myself. Any photos that I might deem worthwhile getting printed will be dealt with by the likes of Asda or Max Spielman (or whoever) where proper photo printing technology will provide prints at least as colourfast as the traditional photo printing from film media (the same chemistry just raster scanned with laser beams instead of directly projecting an image from a colour negative). True. I just don't print photos at all except when I chose to front the magistrate after having got booked doing 160KM, to show him that there was no danger doing that speed there. Didn't end up actually needing to show him the photos, he let me off after I lied to him. In my opinion, no home inkjet photocolour grade printer can compete for cost and quality when asked to print photos. True. Once you've cast that 'advantage' aside, there's no point in wasting money on another inkjet except, perhaps, on one designed specifically for printing to optical media using cheap ink carts Yeah, that's the reason I got that printer. (preferably able to use a dedicated black ink when monochrome is all that is needed rather than force you to consume an expensive set of colour carts to print the job in photo black). I just use one of the colors and print in that. However, optical media seems to be going the way of the Dodo (afaiac) so maybe not. Yeah, I don't use it much anymore. Can be convenient to post them, we can post them for the normal letter stamp. You can do that with SD cards too, but with the blanks you don't care if they come back or not and they work better for the techklutzes that usually can manage to put a DVD into something they have to play the TV program that they missed or that they have got me to download for them. I suppose we're still going to have to 'fiddle' our own fixes to the 'consumerism' driven 'planned obsolescence' of toner carts that rely on a counter to prematurely declare exhaustion (in one case, according to the recent BBC programme, "The Men Who Made Us Spend", by a 'safety margin' factor of three!). I just ensure that I don't buy those by researching them properly before buying them, but that has changed a bit now with that stuff showing up at garage sales and facebook buy sell swap groups for peanuts. I've no doubt the printer manufacturers will continue to erode durability of laser printers and carts in their never ending quest to shake down their 'consumer' and milk the suckers[1] for all their worth. Yeah, but it will be interesting to watch how many bother to print much into the future. I print almost nothing now, just the CDs and DVDs mostly. The last thing I printed was a blowup of my driver's license that I needed when claiming some unclaimed money of mine. Their system did have a decent online form to fill in, but printed that and wanted a copy of that sort of proof of identity stuff posted to them. You couldn't upload that. I've just done something similar for someone I know who had to submit some documentation for a permanent resident visa who doesn't have a printer or net service either. The way the Printer Manufacturers are carrying on, the dream of a "Paperless Office" might finally come true a lot sooner than anyone would have expected! :-) Yeah, it will be interesting to watch.

You don't need to print anything to stop them blocking up. If you leave it on the printer will clean itself as needed. My Brother aio has been sitting there happy for four years now. It doesn't use much power as all it is doing is keeping the network alive so it can wake up and print when required. The ink level goes down slowly but you are talking about years if you don't print anything. And as it uses optical level sensors you can refill or use £1.99 carts in it. |
