I know you don't like serial printers but I love em and to date have had no problems at all really. And the trouble is if you exclude them you're missing out on half of the printing hardware that's available out there - and I also bank on the fact that because you talk them down, that helps keep the price low as well ;-)
Take a look at the attached pics.
Rcpt1.jpg shows how nicely a normal receipt (2) and a gift card (1) print on a parallel printer (Epson thermal).
Rcpt2.jpg shows what's happening on a serial printer (CBM thermal). There has always been a small problem on a normal receipt (3) where indicated because of a missing LF before the underline above the total row but this has never caused a major problem and I've always just lived with it. However, the gift card and its accompanying receipt aren't printing at all. There's no formatting at all and the paper cut commands aren't present either.
Can you do anything?
Followed by some graphics of some receipts.
To which I replied
Let's see here, you are the 3rd email I have received today about a serial printer not doing something correctly. BTW, the total number of emails I have received about parallel printers messing up over the last 7 years still stands at zero.
I am glad that serial printers are working perfectly for you except of course you are sending me an email about a serial printer not working perfectly. (At this point Dale beats his head against his desk until it starts to bleed.)
So I guess you are correct in that a serial printer works just as fine as a parallel printer and that the dozens of emails and phone calls I get every week asking for help with serial printers are just an illusion on my part, they don't really exist, including this one. But I will answer this one anyway.
While I cannot think of anything more fun than fruitlessly spending hours, days, or weeks trying to untangle the knotted, vine encrusted problems that you are having with your serial printer my wife, family, and mental health professionals have all insisted that that I no longer attempt this. Plus my employer really wants me to come into work on a regular basis instead of devoting all my time to the arcane mysteries of serial printers. So I am left with only one solution to your problems which has a 100% success rate and will work instantly. GET A PARALLEL PRINTER!
See, problem solved.
Anything else I can help you with?
When will this nightmare end?
