See if the printer has a little toggle switch for "auto linefeed" and turn it off. What brand printer? Does it use standard ESC P2 sequences like an Epson? Regardless, there should be a sequence for "doublestrike" or "bold". Or you might find a sequence for "reverse linefeed". Joe Fischer ###### From: lester5374@aol.com.Tony.C.

I had already given that some thought, but to do it, I would have to manually break the original file into multiple files. And since not every line os overprinted and the overprint is not always the same number of times for each finished line, I would have to break up the original file, then go back to each separate file and manually add line feed to "line up" the lines. WAY to much manually editing for my liking. I prefer the output of my Hewlett Packerd Laserjet 5p to the dot matrixes I still have around here, so if I can not find a way to use the laser, I'll just go back to the Dot printers (until they break for good!).

The HP uses PCL programing. There are Line Termination controls that "should" effect how the CR+LF codes in single and combination are interpreted. But in another place in the HP codes it says that the LF (linefeed) ASCII 10 is interpreted as CR (carriage return) ASCII 13. Since a laser places toner on the drum as it goes (I am assuming here), I was hoping someone else in the group could either confirm that "overprinting" is impossible, or they could give me a hint at how to control the printer to properly process the file. BTW, the print file contains 130 printable characters per line. If the line is actually supposed to advance, there is a CR and LF at the the end the line. If there is to be overprinting there is just a CR at the end of the line. ###### From: "Meph" Newsgroups: alt.ascii-art Subject: Re: overprinting ASCII on Laserjet?

Also check for bi-directional printing, and duplicate the line without a CR or linefeed (this may not apply to certain laser printers). The standard widths were 80 column and 132 columns, and some really wide ledger size. My Epson inkjet uses pretty much the same standard ESC 2P as the Epson line printers, and it prints ASCII fine. I tried to print ANSI color, but gave up, and I use NEOgrab to convert ASCII and ANSI screens to gif for printing now. But to do more than 25 lines, it would require breaking up the ASCII file into segments, and then glue them together after printing. Joe Fischer ###### From: lester5374@aol.com.Tony.C.

These are called line printers. Dot matrix fit this, daisy wheel did also, some inkjets may still do. Lasers (and most inkjets) are page printers. In these the entire page is rendered onto an large slab of RAM (like an video cards display RAM) and then tranfered at once to paper. Overprinting simply sets RAM bits, which are allready set. So you see no effect, despite them being set twice. Bits are 0 or 1, setting them twice does not make an 2 out of them. The nearist thing you can do is get an program that understands overstriking and converts it into escape sequences for bold printing. Like the GNU "less" file viewer does. BTW: printing the line twice with CR is the wrong way for most of these programs, they usually want ..., they also user to underline.

Have you ever looked at one of these files? Before Dot matrix all there was were line printers, so therefore you had to print a whole line at a time. So you print a line of 0's, then you overprint with a line of #'s, then you print a third time on the same line with X's. I understand that Laser printers are page printers and that each character is sent to the printer as a bunch of dots to fill up a space. We will assume we are using a mono spaced font (since it is required for these type of line posters) and that each character will partially fill in a rectangle of dots (hence the 300x300 dot resolution from Dot matrix that is also a part of Laser printing). So "overprinting" on a Laser printer is simple a matter of filling in the rectangle that will hold the three characters that occupy the same space. If you start with a 0 then put a # in the same space you should fill in more or the dots in our "rectangle", that when you add the X to the mix you fill in even more dots in our rectangle. I still think some combination of the use of the "Transparency" setting on the HP may solve this, but I have not been able to find a good example of how to use it in this situation, and my trial and error hasn't produced any usable results. I have seen too many print errors where text overwrote other text on my laser to just give this up as hopeless. I was sure that someone in this group would have already worked out how to print the old line printer posters on a laser printer. I can not believe I am the first to try this. The Dot Matrix printer will eventually become an oddity that is only used in special circumstances, so for posterity sake, these "works of computer art" will have to either be converted to a new format or a method worked out to output them to the general printer in use (which is now the laser).

Unless I am to assume the person thought they were smarter and created this file by hand?? In any case all I can think of at this moment is that either your printer needs to go to the shop because its misbehaving or that you should convert the file into a format that "can" be read by todays standards... What OS are you using, MS-DOS/win9x? If you know programming create a C file that will look for all the old characters and either delete them or replace them with something that makes sense... I would still think you could load this into a text editor and hunt for the funky boxes. If you told me what characters seem to be the bad ones I might have time to thrown together a 10 line C program that will fix your silly dilemma. If you can turn it into a postscript format. This is a standard that shouldn't disappear. And there are many converters from postscript to everything else for that matter... tell me what you think?

It should be trivial for someone who knows PostScript to write an ascii-to-ps converter. If your printer doesn't speak postscript, there's always ghostview. Yes, it does seem a bit like swatting a fly with a sledgehammer, but if that's what it takes.. No, I can't write postscript myself.

Possibly broken as designed, but definitely broken. P.S: are you printing directly to the LPTx: from an DOS box or are you printing from some file view/print program (Notepad?) via an Windows driver?

The first computer printers were Teletype ASR 2x and 3x(*) and Friden Flexowriters (I am talking here about the 1950s for mainframes and 1960s for PDPs). These devices all worked one character at a time. ASCII was originally the control code for such devices. That is why it contains such things as BS, you print a > line of 0's, then you overprint with a line of #'s, then you print a > third time on the > same line with X's. Actuall the only line-at-a-time printer I have ever seen (on an Pr1me 750) about 15 years ago) would make this impossible. It used one pin per char and "wriggled" the print assembly a few pixels back and fro, while steadily advancing the paper. Overstrike would have required reversing the paper movement (never an good thing to do). > I understand that Laser printers are page printers and that each > character is sent > to the printer as a bunch of dots to fill up a space.

What good would that do? I would try having an look at the PCL positioning escape sequences. Quasi force the rasteriser to work there where you want it to. I have not got any PCL manual, so I can not point out the actual sequence to use. > I have seen too many print errors where text overwrote other text on my > laser to > just give this up as hopeless. Most likely wrongly calculated positioning sequences. I have done that myself when writing PostScript drivers.
