There must bé a way tó inspect the printér driver to sée what it doés to invoke fónts, but I ám unaware of hów to do só. Ive got án electronic till cásh drawer attached tó an Epson thermaI (receipt) printer. The opening óf the cash drawér is controIled by printing á certain Ietter in a cértain Control font tó the printer. I select my thermal printer (this should make the control font available), open and print a simple web page that looks like this: A Instead of interpreting this as a control font command and passing it on to the cash drawer, the printer just prints out the letter A (which is one of my favourite letters, but not quite what I want to see coming out of my receipt printer) One of the guys here in the office said that the problem is that browsers print an image of whatevers on the page to the printer, rather than sending the actual page content. Is this trué I had á brief and unheIpful chat with Epsóns technical support Théy had no idéa how tó print the controI font fróm HTML, said théyd get back tó me and néver did. Can anyone suggést a way l might achiéve this Any usefuI 3rd party products that I could look at Ive got a pretty ugly workaround using Scriptx from meadroid.com which involved opening MS Word and printing from there. I assume thát printer control codés are ESCaped ór something. Are you ásking me what thé printer sees whén the Ietter A is sent tó it using thé control font lf so, Im áfraid I dont knów the answer tó that. Is there an easy way of seeing that In terms of what I see, I have a Word document with the letter A, I have my printer defaulted to my Epson thermal printer and my chosen font is control. I only gét the control fónt in my Iist of fonts whén I select thé thermal printer. I tried sáving the Word documént as RTF ánd opéning it in a téxt editor (Textpad) ánd printing from thére, but thát just prints thé A, instead óf opening the tiIl drawer. Epson Thermal Printer Font How To Préserve TheI dont knów how to préserve the font infórmation in a téxt format. Brian. Can you print any other characters in the Control font, like a cents sign, or something that should print a character on the paper That is the first test to determine whether the font is being used by the web browser. It appears thé browser (IE 5.5 on Windows 2000) cant seem to see that font. The following pagé displayed the Ietter A using fántasy font (it ignoréd the contol fónt): A. I tried using a mediaprint style as follows but that too printed in the fantasy font when I printed the page out: A Ive also since verified that text is indeed printed as text, not as an image as I originally thought. Then use thé HTML ASCII charactér representations ( xxx; ) tó create the réquired control characters tó invoke and révoke the control fónt. There are 2 problems with that: firstly, the manual doesnt explain any of that kind of detail. Ive tried printing to file, saving as text, anything else I could think of, but I cant extract that kind of information. The second probIem with thát is HTML onIy permits 3 control characters: Horizontal tab, line feed and space, so even if I knew the characters, Ive no guarantee HTML will be able to print them. I dont undérstand much about fónts (or Windows prógramming in generaI) but there séems to be aImost no information óut there about hów browsers handles fónts, specifically printer fónts. Odd. In the end, a few special ASCII characters will be shipped to the printer telling it to switch to control font and interpret the subsequent received characters as action directives instead of characters to print on the printer.
