Hi, This is the second time I am sending this request... I need to print barcode labels from my application (well, it could be more in line with an applet... it is miniscule, really)... Could I get some logic for printing the same, which could be also readable from a scanner ??? I visited some sites as guided out by the members of this group but they were all paid fonts. I cannot afford to spend that... I am getting 3,000 Rs. (75$) only for getting this printing job done... and the fonts cost at least 40 $... and my coding would still be required to be done extra. Thanx, Kapil -

Anyway, what I once did was pull one of the perl modules that does barcodes. There are loads of them. They have a function that takes a strings and returns a list of ones and zeros that represent the barcode. From here I used that list to make HTML output using two images, one 1x1 white pixel and a 1x1 black pixel. Print that and it worked fine. (Well, with my cuecat anyway :) With those perl modules they can also (using the GD library) spit out images in various formats that also show the barcode. If you want to be really tricky, you can even generate postscript to do it. Anyway, hope this helps, -- Martijn van Oosterhout <kleptog@svana.org> http://svana.org/kleptog/ > It would be nice if someone came up with a certification system that > actually separated those who can barely regurgitate what they crammed over > the last few weeks from those who command secret ninja networking powers.

I think you're a bit confused...this list is for general questions regarding PostgreSQL, not just general questions. www.google.com is good for general questions, and I didn't have much trouble finding a free barcode printing utility there last time I was looking for one. -- SPY My girlfriend asked me which one I like better. pub 1024/3CAE01D5 1994/11/03 Dustin Sallings <dustin@spy.net> | Key fingerprint = 87 02 57 08 02 D0 DA D6 C8 0F 3E 65 51 98 D8 BE L_______________________ I hope the answer won't upset her. ____________

Depending on your environment you can either use GNU barcode: http://www.gnu.org/directory/barcode.html or write your own routines. If you just need numbers there is an easy code named 2 of 5 interleaved. You can find a description of the various coding systems at: http://www.barcode-1.net/pub/russadam/info.html#Specs But I definitely recommend using code 128, because it can hold any type of character and has a check digit calculation included avoiding reading errors (in contrary to the above mentioned code). But implementation is more difficult. Hope this helps.

I see there is a GNU barcode (outputs ps/eps) and an "ean13" (outputs xbm). Both free, no special fonts. Don't know how well they'll fit your situation. GNU barcode seems pretty flexible... -- Eric G. Miller <egm2@jps.net>
