need help regarding text printing on linux

hey group,

We need your help regarding the text printing on Linux system.

We are developing thermal printer driver on Linux platform. For this we have to support all commands related to printer.

These commands include text related commands (bold, double height, double width, underline etc), barcode related commands and graphics commands.

Also, there are printer fonts for the text which will be selected by the user.

DVD for Archiving and Backup
I tried using DVD-R last year to make backups, but without much success. I posted here for help, and here is...

We need help for: 1. Text commands support and printing To send commands for changing height,changing width, old, italics and other text parameters.

2. Font creation and usage (Font control type also) * To create fonts and to send specific commands when the text is in "created printer fonts". * "FontControl type" font selection for particular characters are taken as commands not the text to be printed. eg.Suppose we write a character 'g' in text pad with FontControl type of font than in that case Cut receipt command is sent to the printer. How to interpret the text in font control is one of the further issue.

(Through rastering the text is being printed as seen with all the correct parameters (width, height etc.). Overall, "rastering" is working fine for any type of data ; text, image, doc etc.)

Howto implement AND in grep
No need for cat: grep str1 file.txt grep str2 grep str3... Either of the two scripts posted (by Michael Heiming and Peter Breuer) should give you a solution, but Michael's is not complete...

Following are the queries related:

1. What solution do you suggest for this?

2. How can we directly print text to the printer (without using CUPS printing system) with all the supported commands as well as Font selected?

3. Can we put this facility to directly read text not raster data (bypbutting the CUPS system) in the filter (rasterto*)?

3. How can we create fonts on linux so that any text based application can select the available font (fontcontrol type font also) and send command to print the text to the printer?

thanx shail
