I try to print to EPSON POS printer with the Printer object in VB.  The printer driver is loaded.

after I print the control command to the printer for drawer open, the font format in the next printer output is not correct?

Anyone has encountered this problem before?  Is there anything that I can try?

Thanks

Ben

Umm... You tell the drawer to open and the next font used is changed??? That's odd.

Sub Test1
Printer.fontname="16 cpi"
Printer.fontsize=18
Printer.Print "12345"  ' should be in large print
Printer.EndDoc
End Sub

Sub Test2
Printer.fontname="control"
Printer.Print "A"   ' open drawer
Printer.EndDoc
End Sub

Sub Main
     Test1    ' Print out OK
     Test2    ' Drawer Open OK
     Test1    ' Print out in default font(not in large prt)
End Sub

A pos printer does not understand the font 16 cpi,

you need to have a look at the tech side and find out what it likes, its not the same as a normal printer,

thats if you are on the right wave length as me

are we talking POINT OF SALES printer.

cheers

Hi Andy,
I am talking about POS printer.
As documented by EPSON, with the windows driver,
it does support 16 cpi.  I am using TMU200BP printer.

I got the large print output when i first run the Test1.  However, after I execute the Test2 procedure, I will have a normal font size printout from Test1.

How come?  I have read the documentation in MSDN.  It seems like it is the reset problem of the Printer object.  

I need help...
Thank you.

Can't you just reset the font after opening the drawer?

According to the MSDN, I can only reset the printer by quiting the program. :>

Maybe I am just a bit confused, but I meant: Can't you just add "Printer.fontsize=18" to the beginning of Test2?

I am just wondering ... could u use a

printer.newpage

instead of printer.enddoc this should not reset the printer settings. use printer.enddoc to end the entire bill transaction.

Hope that helps.
