I happen to know a thing or two about printing, PDF, PostScript, PJL, Fonts and related stuff.

Also familiar with some bits and pieces of Linux, Unix, Samba and Solaris printing. Not to forget bash programming and Windows cmd.exe batch scripting. I also do consultancy in these topics.

If you want, I share some of this knowledge here and on Stackoverflow (SO). Just click to browse for all.

comment Making ls output like dir /b /s
@grawity: D'oh! You're right of course. (I do it right whenever I need to do it in a shell. Heaven knows why I did it wrong when typing it into the text edit field....) I'll correct my comments so it will not confuse other readers.

comment Generating PDF via command line in PDF Creator doesn't work, works in GUI
HTMLDOC (htmldoc.org) is another utility to directly convert HTML to PDF (or PostScript). Can be put to work on the commandline, with a GUI or as a web servicve.

comment Making ls output like dir /b /s
@grawity: you're right and wrong at the same time. $PWD or ${PWD} would return the content of an environment variable (the current directory). This is what you have in mind. pwd is a little commandline utility ('print working directory') which also outputs the current directory path. Using it as ${pwd} or as `pwd` would return the result of that command, which in this case has the same effect as using $PWD. So my version will definitely work, and your comment was not appropriate in this context.

comment ubuntu 9.10 cups server cupsd.conf
That's not correct. What you indeed do have to avoid is multiple Listen ... statements with overlapping sockets. What is completely "legal" with CUPS is having 2 (or more) separate Listen ... statements, one with Listen 127.0.0.1:631, another one with Listen 192.168.1.101:631. These do not overlap. What will always overlap is to use wildcard statements, such as Listen *:631 and also add specific ones such as Listen 192.168.1.101:631.

comment How do you type Unicode characters using hexadecimal codes?
you can also calculate with set /a in a command window ;-). To convert hex=4321 into decimal, just type set /a 4*16*16*16+3*16*16+2*16+1 and the result will show up as 17185

comment How do you type Unicode characters using hexadecimal codes?
@Arjan: you do not type hex chars with the "alt+nnn" method. You do only type decimal character codes. That's why you cannot type even straight "U+1234" strings (which do not contain any of your loathed "a-f" characters) into your numeric keypad as "alt+1234", but you need to convert hex==1234 into dec==4660 and then type "alt+4660" before you (MAY) get what you want. So your statement "using the Alt-trick does not work for hexdecimal codes" nails the problem exactly, but you missed to understand it yourself :-)

comment How do you type Unicode characters using hexadecimal codes?
@Will: the "alt+NN..." method expects decimal, not hex notation of the character position. Unicode uses hex. So if you want to type what Unicode represents as "U+23AF" you need to convert hex==23AF into decimal==9135, and then type "alt+9135". That's the only general method there is on offer. But: You wanted character may still not appear as expect in the text field or document, if your currently selected font does not have the "U+23AF" place filled (or if it is not a Unicode font in the first place!).

comment How can I type U+200B character?
@RobertPitt: if you want to use the "alt+NMO" method with numeric keypad, the "NMO" part must not be the identical string as the Unicode codepoint description. Unicode codepoints are given as hex values. The "alt+NMO" method needs decimal values. You MUST convert the Unicode "NMOP" into a decimal. Then use "alt+<decimal-of-NMOP>" on your numeric keypad. (Doesn't work for me with the examples Mehper had given, I don't have fonts. But works for all cases of "normal" characters, as well as characters which are displayed by my local charmap.exe.)

(After all, there are tons of OCR'd PDF documents out there. And OCR working with 99% accuracy is already regarded as "good". (But looking from the p.o.v. of a high school teacher, any text that has 10 spelling errors for each 1000 characters is earning one of the worst school grades you can imagine....)
