7 Introduction This sec tion con tains in for ma tion about the ba - sic fea tures, com mand syn tax and ter mi nol ogy of the EPL2 programming language for Ze bra's desk top print ers with flash mem ory ar chi tec - ture. These printers incorporate common pro - gram ming code sets and ar chi tec tural fea tures. The pri mary op er at ing mode for the printer is EPL2, a page de scrip tion lan guage. EPL2 is an ideal lan guage for your la bel ing and bar code re quire ments. It is de signed to as sem ble all the el e ments of the la bel prior to print ing to speed print ing. EPL2 is ver sa tile and ca pa ble of print - ing graphics, a wide range me dia and bar codes. Some di rect ther mal printer mod els also in clude a leg acy printer com pat i bil ity mode, Line Mode. Line Mode sup ports our early model EPL pro gram ming lan guage - ELP1. A sep a rate man ual is pro vided for Line Mode print ing (p/n ). See the printer s Soft ware and Doc u men ta tion CD for pro gram mer s manual that ap ply to your printer or visit our web site at: Rev.E 1-1

8 Command Conventions The man ual uses the fol low ing ty po graphic con ven tions to de scribe com mands. Ex am ple A De scrip tion Commands (Case Sensitive) p 1,p 2,p 3 Re quired pa ram e ters [p 1, p 2, p 3 ] Op tional pa ram e ters {Choice 1 Choice 2} Indicates a mandatory choice be - tween two or more items. You must in clude one of the items un - less all of the items are also en - closed in square brack ets. This text should be on one line NAME The line-con tin u a tion char ac ter ( ) in di cates that code is con tin - ued from one line to the next and should be typed all on one line. Line feed char ac ter. The name of a form or graphic in dou ble quote marks. DATA The text or bar code data in dou - ble quote marks. The (\) char ac ter des ig nates that the char ac ter fol low ing is a lit eral and will en code into the data field. Re fer to the fol low ing ex am - ples: To Print En ter into Data Field \" Company \"Company\" \ \\ \code\ \\code\\ PROMPT An ASCII text field that will be trans mit ted to the host (via the se - rial in ter face) each time this com - mand is ex e cuted. Attention!! All com mands and al pha char ac ter com mand parameters are case sen si tive! Rev.E

9 Basic Command Syntax Figure 1-1 Basic Command Syntax Each com mand con sists of one or two ASCII (case sensitive) alpha characters to identify the spe cific com mand de sired. Some com mands require one or more additional parameters to supply the printer with sufficient information to com plete the com mand. Re fer to Fig ure 1- for the ba sic com mand syn tax. Command Name WRITE TEXT A p,p,p,p,p,p,p,"data" Command Parameters Command Specific Data Each com mand line must be ter mi nated with a Line Feed (LF) char ac ter (Dec. 10). Most PC based sys tems send CR/LF when the En ter key is pressed. The Car riage Re turn (CR) character is ig nored by the printer and can not be used in place of LF. Command Editor One method to cre ate com mand files is through an ASCII based text ed i tor. In the DOS en vi ron - ment, MS-DOS EDIT or BRIEF are good choices. In the Win dows en vi ron ment, TextPad for Win dows is a good choice and is available for down load of a free eval u a tion copy at: To ex e cute the file, use the ed i tor s print com - mand or from the DOS prompt, use the COPY com mand to send the file di rectly to the printer. An ex am ple of the use of the COPY com mand is: COPY FILE NAME.EXT LPT1 or COPY FILE NAME.EXT COM1 For more in for ma tion on the use of the COPY com mand, re fer to your DOS soft ware man ual. Con fig ure the COM port to match the printer s se rial port set ting (typ i cally set to de faults). See the Y com mand in sec tion 2 for de tails Rev.E 1-3

10 Placing Elements in the Print Image Sample Format Im age el e ments are lo cated in the im age print buffer on a X-Y grid ex pressed in dots. The X value rep re sents the width and the Y value rep - re sents the height of the grid. The point of or i gin (the start ing point) for a non-ro tated ob ject is the up per left cor ner. As an ob ject ro tates, the point of or i gin ro tates with the ob ject. These im age buffer prop er ties are de picted graph i cally in the fol low ing il lus tra tion. Point of Origin for Text Object x axis (0,0) y axis Text "q" dots Text Point of Origin for Text Object Rotated 90 Point of Origin for BarCode Object Text "Q" dots Direction Of Feed Point of Origin for Text Object Rotated 270 The min i mum non print ing mar gin on all edges of the la bel is 1mm. Print ing closer than 1mm to the top or bot tom edge of the la bel may cause the printer to ad vance un wanted la bels or cause the printer to go into er ror con di tion Rev.E

11 Text (Fonts) The stan dard EPL2 printer has five (1-5) res i - dent mono-spaced dot fonts. Fonts A-Z and a-z (up per and lower case al pha char ac ters) are re - served for down loading soft fonts. First Character of Text String Reference Point 12 D o t s 8 Dots Character Width Total Character Width Inter-character Space (actually white dots) Con trol text height (in hor i zon tal dots) and width (in ver ti cal dots) with the hor i zon tal and ver ti cal mul ti pli ers.

The ref er ence point of the first char ac ter in a text string is not af fected by the font size mul ti plier val ues Rev.E 1-5

12 Total Character Width 8 Dots Character Width The stan dard Latin font (1-5) and soft font char - ac ters are dot mapped dif fer ently than the Asian font (8 & 9) char ac ters. The Asian char ac ter does not have a built-in inter-char ac ter gap. The Latin char ac ters in clude a sin gle dot bor der around each char ac ter.

14 Language Character Sets (Fonts 1-5) Asian Character Sets (Fonts 8 & 9) The Latin based lan guage and Greek char ac ter sup port is con trolled and en abled with the I com mand, see page The de fault lan - guage set is the Eng lish DOS codepage 437. Char ac ters, like the Euro sym bol, can be sub sti - tuted us ing the or com mand, see page The Page Mode EPL2 pro gram ming lan guage sup ports up to two (2) font sets of a sin gle Asian lan guage as well as the stan dard EPL2 Latin (Multilingual) fonts 1-5 and downloadable soft fonts (A-Z and a-z). Asian lan guage sup port is an op tional fea ture and re quires a spe cial ver sion of the printer (PCBA) to sup port the large Asian char ac ter sets. The flash based print ers sup port up to five different Asian language character (ideo gram) sets, see the A com mand on page 3-4 for de - tailed list of of fonts. For Asian lan guage firm ware up dates, pub li ca - tions and sup port op tions see: All fonts can be ex panded both hor i zon tally and ver ti cally. The Asian fonts can also be printed from top to bot tom or in the Latin char ac ter ori - en ta tion from left to right. The Asian print ers sup port the stan dard Latin fonts with the sin gle char ac ter map code page 437 for all five (5) fonts. The Asian char ac ters are 16 bit (or dou ble byte) mapped char ac ters. The printed Asian char ac - ter is de pend ent on the dou ble byte ASCII val - ues. The Latin (Eng lish, etc.) font sets are 8 bits per (or sin gle byte) ASCII char ac ter maps. Only One (1) Asian lan guage is sup ported by a printer. Each Asian lan guage (char ac ter set) is a separate printer firmware version. Asian print ers with flash firm ware can be re pro - grammed for a dif fer ent Asian lan guage, but we do not rec om mend this for nor mal use Rev.E

15 Chinese Character Set The printer automatically recognizes single byte characters and double byte characters. The sin gle byte font char ac ters are mapped to hex a dec i mal ad dress range 00 to 7F hex (0-127 dec i mal) for 203 dpi print ers and 00 to FF hex (0-255 dec i mal) for 300 dpi print ers. The dou ble byte font char ac ters are mapped to hex a dec i mal ad dress range A1A0 to F7FF hex. First byte, 161 (A1h) and sec ond byte 160 (A0h) to first byte, 247 (F7h) and sec ond byte, 255 (FFh) is the dec i mal, grouped byte range. Chinese Fonts 8 & 9 Double Byte Ideographic Characters The Chi nese ideographic font char ac ters are mapped to double byte hexadecimal address range A1A0 to F7FF hex. See the fol low ing pages for the codepage character mappings. Simplified dpi printers Simplified dpi printers Traditional dpi printers Rev.E 1-9

16 Japanese Character Sets Codepage Ref er ence Range The printer automatically recognizes single byte char ac ters and dou ble byte char ac ters in the Shift-JIS codepage. The sin gle byte font char ac - ters are mapped to hex a dec i mal ad dress range 00 to 7F hex (0-127 dec i mal) for 203 dpi print - ers and 00 to FF hex (0-255 dec i mal) for 300 dpi print ers. The dou ble byte font char ac ters are mapped to hexadecimal address ranges (see below).

18 Bar Codes All bar codes sup ported by the EPL2 lan guage have associated industry specifications that the pro gram mer should be aware of and ad here to. The pro gram mer needs to con sider bar code fea tures and re quire ments when choos ing and us ing a bar code for dif fer ent ap pli ca tions. Some of the fea tures and re quire ments that need con sid er ation are listed be low: Data used by the ap pli ca tion are per the bar code specification (numbers only, alphanu - meric, alphanumeric and special characters, etc.). Min i mum and max i mum num ber of char ac - ters al lowed or re quired per bar code. Den sity or mag ni fi ca tion of a given bar code type. White area re quired around bar codes (the Quiet Zone ). The bar code must print within the im age buffer (print able area of the la bel).

19 QR Code Bar Code The QR Code bar code is only of fered with Jap - anese Character bar code printer configura - tions. Programming Sequences Affect Graphic Results Graphic el e ments can in ter act and the re sul tant image can be affected by other commands. Structure command sequences to reduce the chances of unexpected print results. The printer will process lines, text, boxes and most bar codes in command sequence. The printer then processes the printer control processes, counters, variable data, Postnet, and then graphics last Rev.E 1-13

23 Programming Mode Configuration Manually Setting Line Mode Flash based print ers are, by de fault, con fig ured for Page (EPL2) mode op er a tions. The op er a - tor must con vert the printer to Line Mode prior to the ini tial use of Line Mode. This is done via a hard ware se lect pro ce dure with the Feed but ton dur ing printer power-up. See the OEPL1 com - mand (page 3-101) for de tails on switch ing be - tween line and page modes via pro gram ming.

24 Media Detection Me dia de tec tion in EPL2 print ers is a com bi na - tion of pro gram ming and printer me dia sens ing. The Q (Set Form Length) and O (Op tion) com - mands pro gram the me dia de tec tion method. The user must con fig ure the printer for the me - dia type and the (pro grammed) form or la bel in use. The printer can de tect the be gin ning and end of the print able area on the me dia by one of three meth ods: Gap, Notch (hole), or Black line. The Gap method de tects the dif fer ence in op ti cal den sity of a la bel on a liner from the liner only with the Transmissive (Gap) sen sor. The Notch method uses the Transmissive sen sor to de tect a hole in the me dia (gap-less la bels or tag stock). The Black line method uses the Re flec tive sen - sor to de tect a preprinted black line on the me - dia back (for gap-less la bels or tag stock). Print ing on con tin u ous me dia re quires pro - gram ming to con trol me dia po si tion ing. EPL2 print ers also sup port a La bel Dis pense mode as a printer con fig u ra tion op tion (for most mod els). The print ers use a La bel Taken sen - sor to de tect the re moval of a la bel. One or more of these sen sors may re quire user adjustment or configuration for proper opera - tion. All EPL2 print ers have an AutoSense fea - ture to op ti mize la bel and la bel gap de tec tion by the transmissive (gap) sen sor. See the printer s user s man ual for printer spe cific sen sor ad just - ment con trol Rev.E

25 Command Reference Memory and Command Usage This sec tion con tains a com plete list ing of all com mands in al pha bet i cal or der. How of ten should a com mand be used to change a set ting, to make a la bel, or en able re - port ing? Were that com mand stores mem ory af fects these de ci sions. The printer stores con - figuration settings, fonts, graphics (logos) and la bel form files into printer mem ory. The Com - mand Ref er ence in cludes a Memory col umn with the fol low ing terms: Im age com mands are use to as sem ble the printed la bel im age in the print im age buffer. Form com mands are only used within forms. Session commands place the configuration set ting in tem po rary RAM mem ory. The set ting re verts to the printer de fault when the printer has power cy cled or is re set. Stored mem ory com mands will check for dif - fer ences with the ex ist ing com mand set ting prior to val i dat ing a mem ory write op er a tion. The printer's non-vol a tile "flash" mem ory has a lim ited num ber of write cy cles (100,000 plus). Writes to mem ory com mands are com mands that do not check to see if a set ting, file, font, char ac ter or graphic is al ready pres ent or if that con di tion is al ready set. These com mands are rarely used in forms ex cept as a printer ini tial iza - tion and function oriented configuration Rev.E 3-1
