Morning,

I want to be able to print some text to the far left.

Example
1 x Bread                      £1.00        

But if my middle text is longer then it miss-aligns the £0.00

Example

1 x Bread                      £1.00        
1 x Newspaper                   £1.00

I need to have the £1.00 all align to the left no matter how many chars there are. I am using the Epson ESC commands to the printer directly via the serial port.

What command should I be using? Also does anyone know of any good examples on the www?

I am using vb.net

@  richard_gar :

How are you formating your output in your application. Are you using VBA ? Pl.put your print command /function which you are using in your APP.
Infact you will have to use rset function to right set the variable's value , before sending it to printer.

You format your line like this :

   Grossq = Space(10)
   Grsosss=Space(10)
   RSet Grossq = Format(txtGrossQty1.text, "########0.0")
   RSet Grosss = Format(txtGrosssales1.text, "########0.0")
   serialPort.Write(" GROSS                 " +Grossp+"   "+Grosss)

The above line will adjust your grossqty, and gross sales value from right alignment with proper spacing
of 10, now you can calcualate the lenght of your item description and can put max.space-calculated space between the item description and gross qty/gross sale

how is that going to work?

As if I have 10 spaces between them

it would like so:

1 x  bread          £1.00
1 x newspaper          £1.00

you see I have 10 spaces from bread and newspaper I need a way to make the £1.00 be at the far left of the receipt no matter how many chars there are before it.

The description of the product will never be more than 255 chars.

Is there a way to tell the £1.00 to print to the far left no matter how many chars there are in the description like so:

1 x bread             £1.00
1 x newspaper    £1.00

Do it like this :
   Grossq = Space(10) ' It will assign space 10 for Gross qty value/width
   Grsosss=Space(10)  'It will assign space 10 for Gross sales value/width

   RSet Grossq = Format(txtGrossQty1.text, "########0.0")
   RSet Grosss = Format(txtGrosssales1.text, "########0.0")

   serialPort.Write(trim(itemdescription)+space(100-trim(itemdescription))+Grossq

Assume your max item description length in your table is 100, increase/decrease this number  if req. to increase/decrease space between item description and gross qty.
